2. introduction
This paper describes the main challenges
and opportunities in modeling and
optimization of supply biomass bioenergy
productions. It reviews the main routes of
energy from biomass for bioenergy from
terrestrial and aquatic products for
biofuels.
3. introduction
Global biofuels production is growing
steadily and will continue. Biofuels offer
greater energy security, reduced
greenhouse gas emissions and particulate
matter, rural development, better vehicle
performance and a reduction in oil
demand.
4. Why?
It is not a secret that fossil fuels
(hydrocarbons) are finishing and we only
hace resources for 20 years more, these are
causing pollution, greenhouse damage to
the ozone layer and therefore global
warming; this is the reason why new
alternatives are sought to meet these
energy demands.
5. Cause
In this paper we study the ability of
biomass to produce biofuels as these are
more environmentally friendly,
inexpensive and can be obtained from a
variety of sources; that is the reason for
studying several alternatives for the
production of these.
6. How?
We look for to optimize supply chains of
biomass for bioenergy, from aquatic and
terrestrial biomass, moving from the
laboratory to industrial plants behave like
looking at these substrate concentrations
to reproduce, high pressures and
temperatures than operate among
others.
7. Terrestrial raw materials
Many types of biomass are available, the
first group includes grains of corn, sugar
cane, soybeans, oilseeds, etc.. These raw
materials are high in sugar or fat, and
have a high yield after converted into
bioethanol or biodiesel.
8. Terrestrial raw materials
the use of these raw materials for the
production of biofuels could cause
problems in terms of food prices and
production.
The second group of materials are not
edible starch, agricultural waste and
forestry residues other crops
9. Aquatic raw materials
Aquatic Biomass includes a diverse group
of photosynthetic algae and
cyanobacteria ranging from (microalgae
and cyanobacteria) to large seaweeds
(macroalgae) Many macro algae, micro
algae and cyanobacteria serve to drive
the rapid growth of biomass. Certain
strains make extremely efficient use of
light and nutrients to grow.
12. methodologies used
biochemical technologies
The main biochemical conversion processes
include pretreatment, hydrolysis, biological or
chemical processing.
thermochemical technologies
used in addition to high temperature catalysts to
change the physical properties and chemical
structures of biomass resources. There are two
major pathways thermochemical reaction:
gasification and pyrolysis.
14. inference
These are endless advantages and
applications which have the production of
biofuels, since they reduce the
environmental impact considerably and
also help meet the demand for oil in the
world, as this is more cost-effective
renewable and more environmentally
friendly.
