Gasification is a process that converts carbon-based materials like coal into a gaseous fuel called synthesis gas (syngas) through a series of chemical reactions in a gasifier. Syngas is composed primarily of carbon monoxide and hydrogen. The gasification process involves partial oxidation using oxygen and steam, producing syngas and leaving mineral residues. Key reactions in gasification include dehydration, pyrolysis, combustion, and the gasification reaction where char reacts with carbon dioxide and steam to produce carbon monoxide and hydrogen. There are three main types of gasifiers: fixed-bed, entrained-flow, and fluidized-bed gasifiers.

Biomass gasification - types and principlesAyisha586983
Biomass gasification is a thermochemical process that converts solid biomass materials into a gas mixture called syngas (synthesis gas), which is primarily composed of hydrogen (H2), carbon monoxide (CO), and methane (CH4). This process involves partial oxidation of biomass in a controlled environment with a limited supply of oxygen or steam. Biomass gasification offers a versatile and sustainable method to produce renewable energy, chemicals, and fuels.
This is a report on the design of a plant to produce 20 million standard cubic feet per day (0.555 × 106 standard m3/day) of hydrogen (H2) of at least 95% purity from heavy fuel oil (HFO) with an upstream time of 7680 hours/year applying the process of partial oxidation of the heavy oil feedstock.
PRODUCTION OF ALTERNATIVE FUEL USING GASIFICATION BY SYNTHESIS OF FISCHER-TRO...IAEME Publication
The solid carbonaceous fuel is converted into combustible gas (energy) using limited amount of air it is called Gasification process the gases which evolve are known as “producer gas”. This is more suitable than the direct combustion of biomass gases. In this paper an updraft gasifier is construct and is used to carry out the experiment. updraft gasifier is one of the boiler. The waste material like coconut shells, sugarcane waste, and wood particles are used for the generation of producer gas. The sense of this paper is to study the effect of waste products (coconut shells, sugarcane waste, and wood particles) in form of biomass. The performance of the gasifier is evaluated in terms of zone temperature with different air velocity. By taking the different fuels and varying the air flow rate the temperature of the zones are analysed. The arrangement of tar is also seen in this apparatus. After analysis the maximum temperature give for coconut shell (waste) all three place as compare to other two .so coconut shell is the best suitable material for this gasifier.

Episode 3 : Production of Synthesis Gas by Steam Methane Reforming
History of Synthesis Gas
In 1780, Felice Fontana discovered that combustible gas develops if water vapor is passed over carbon at temperatures over 500 °C. This CO and H2 containing gas was called water gas and mainly used for lighting purposes in the19th century.
As of the beginning of the 20th century, H2/CO-mixtures were used for syntheses of hydrocarbons and then, as a consequence, also called synthesis gas.
Haber and Bosch discovered the synthesis of ammonia from H2 and N2 in 1910 and the first industrial ammonia synthesis plant was commissioned in 1913.
The production of liquid hydrocarbons and oxygenates from syngas conversion over iron catalysts was discovered in 1923 by Fischer and Tropsch.
Much of the syngas conversion processes were being developed in Germany during the first and second world wars at a time when natural resources were becoming scare and alternative routes for hydrogen production, ammonia synthesis, and transportation fuels were a necessity.
In 1943/44, this was applied for large-scale production of artificial fuels from synthesis gas in Germany.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

2. INTRODUCTION
Gasification is a technological process that can
convert any carbonaceous (carbon-based) raw
material such as coal into fuel gas, also known as
synthesis gas (syngas for short). Gasification
occurs in a gasifier, generally a high
temperature/pressure vessel where oxygen (or
air) and steam are directly contacted with the
coal or other feed material causing a series of
chemical reactions to occur that convert the feed
to syngas and ash/slag (mineral residues).
IGCC
3. FUNDAMENTALS OF GASIFICATION
Gasification is a partial oxidation process.The term partial
oxidation simply means that less oxygen is used in gasification
than would be required for combustion (i.e., burning or complete
oxidation) of the same amount of fuel.
Gasification typically uses only 25 to 40 percent of the
theoretical oxidant (either pure oxygen or air) to generate
enough heat to gasify the remaining unoxidized fuel, producing
syngas.
The major combustible products of gasification are carbon
monoxide (CO) and hydrogen (H2), with only a minor amount of
the carbon completely oxidized to carbon dioxide (CO2) and
water.
The heat released by partial oxidation provides most of the
energy needed to break up the chemical bonds in the feedstock,
to drive the other endothermic gasification reactions, and to
increase the temperature of the final gasification products.
IGCC
5. REACTIONS & TRANSFORMATIONS
. The chemistry of gasification is quite complex and is accomplished
through a series of physical transformations and chemical
reactions within the gasifier.
Dehydration – Any free water content of the feedstock
evaporates, leaving dry material and evolving water vapor which
may enter into later chemical reactions.
Pyrolysis –This occurs as the feedstock is exposed to rising
temperature in the gasifier. Devolatization and breaking of the
weaker chemical bonds occurs, releasing volatile gases such as
tar vapors, methane, and hydrogen, along with producing a high
molecular weight char which will undergo gasification reactions.
Combustion –The volatile products and some of the char react
with limited oxygen to form carbon dioxide (CO2), carbon
monoxide (CO), and in doing so, provide the heat needed for
subsequent gasification reactions.
IGCC
6. Gasification –The remaining char reacts with
CO2 and steam to produceCO and hydrogen (H2).
Water-gas-shift and Methanation –These are
separate reversible gas phase reactions taking place
simultaneously based on gasifier conditions.These
are minor reactions which play a small role within in
the gasifier. Depending on the desired product, the
syngas may undergo further water-gas-
shift and methanation processing downstream from
the gasifiers.
IGCC
7. In the low-oxygen, reducing environment of the gasifier,
most of the feedstock’s sulfur coverts to hydrogen sulfide
(H2S), with a small amount forming carbonyl sulfide (COS).
Nitrogen chemically bound in the feed generally converts
to gaseous nitrogen (N2), with some ammonia (NH3), and a
small amount forming hydrogen cyanide (HCN).Chlorine is
primary converted to hydrogen chloride (HCl). In general,
the quantities of sulfur, nitrogen, and chloride in the fuel
are sufficiently small that they have a negligible effect on
the main syngas components of H2 and CO.Trace elements
associated with both organic and inorganic components in
the feed, such as mercury, arsenic and other heavy metals,
appear in the various ash and slag fractions, as well as in
gaseous emissions, and need to be removed from the
syngas prior to further use.
IGCC
8. SYNGAS
Syngas is Composed primarily of the colorless,
odorless, highly flammable gases such as carbon
monoxide (CO) and hydrogen (H2).
Syngas has a variety of uses.
It act as an intermediate in the production
of synthetic natural gas.
It can be converted (or shifted) to hydrogen and
carbon dioxide (CO2) by adding steam and
reacting over a catalyst in a water-gas-shift
reactor.
IGCC
9. Furthermore, hydrogen made from coal or other
solid fuels can be used to refine oil, or to make
products such as ammonia and fertilizer. More
importantly, hydrogen enriched syngas can be used
to make gasoline and diesel fuel. Polygeneration
plants that produce multiple products are uniquely
possible with gasification technologies. Carbon
dioxide can be efficiently captured from syngas,
preventing its greenhouse gas emission to the
atmosphere and enabling its utilization (such as
for Enhanced Oil Recovery) or safe storage.
IGCC
10. SYNGAS COMPOSITION
The composition can vary significantly
depending on the feedstock and the gasification
process involved; however typically syngas is 30
to 60% carbon monoxide (CO), 25 to 30%
hydrogen (H2), 0 to 5% methane (CH4), 5 to 15%
carbon dioxide (CO2), plus a lesser or greater
amount of water vapor, smaller amounts of the
sulfur compounds hydrogen sulfide (H2S),
carbonyl sulfide (COS), and finally some
ammonia and other trace contaminants.
IGCC
11. The discussion of syngas composition is of
considerable importance considering the
varying requirements on composition and
impurities demanded according to final uses
of the syngas.The following table shows the
widely varying characteristics desirable for
the principal uses of syngas, including use as
fuel gas to fire boilers or turbines
in power cycles, use of syngas as feedstock
for production of synthetic fuels such
as gasoline, use as feedstock
for methanol synthesis, and use as feedstock
for production of hydrogen.
IGCC
12. Types of Gasifiers
Although there are various types of gasifers
(gasification reactors), different in design and
operational characteristics, there are three
main gasifier classifications into which most
of the commercially available gasifiers fall.
These categories are as follows:
Fixed-bed gasifiers (also referred as moving-
bed gasifiers)
Entrained-flow gasifiers
Fluidized-bed gasifiers
IGCC
14. The syngas can, after cleaning, be combusted in
a gas engine resulting in an electrical efficiency
in the range of 22–35%. Another option is to
combust the syngas in a gas turbine, which gives
an electrical efficiency of up to 40.The syngas
can also be further upgraded into methane in
a methanation process.This product is often
referred to as substitute or synthetic natural gas
(SNG).The SNG could be fed into the natural gas
grid and be used in conventional stationary gas
utilities, or alternatively, as fuel in the
transportation sector. As indicated, also liquid
transport biofuels can be produced from the
syngas, including, for example, Fischer–Tropsch
diesel and methanol.
