Biodiesel and diesel mixtures were tested in a makeshift bomb calorimeter to measure their energy outputs and see how biodiesel content affected energy levels. Five mixtures with varying biodiesel percentages were ignited in a crucible and the temperature changes measured. The results showed that energy output gradually decreased as the percentage of biodiesel in the mixtures increased, with pure diesel providing the most energy and mixtures with more biodiesel providing less, indicating that biodiesel has a lower energy output than conventional diesel.

2 changes in state
The document discusses the three main ways that the state of matter can change: evaporation, sublimation, and condensation. Evaporation occurs when a liquid turns to a gas above its boiling point, sublimation is when a solid turns directly to a gas, and condensation is when a gas turns to a liquid below its boiling point. It also defines heat of fusion as the energy needed to change from solid to liquid, and heat of vaporization as the energy needed to change from liquid to gas, noting that changing from solid to liquid requires less energy for water.
biodiesel production via acid catalyst and determination of Lower heating values
biodiesel production via acid catalyst and determination of Lower heating valuesNear East University
This document discusses biodiesel production via transesterification using an acid catalyst. It explains that transesterification is a chemical reaction where triglycerides are reacted with alcohol in the presence of a catalyst to produce alkyl esters. Acid-catalyzed transesterification can yield high amounts of biodiesel but results in harder separation of glycerin by-product. Lower heating values are also discussed as being important to indicate the energy density of fuels and varying with different biodiesel blend percentages.Analysis of Vapor Absorption Refrigeration Machine Performance with Different...
The document analyzes the performance of a single-effect vapor absorption refrigeration machine with different cooling water supply configurations. It examines three cases: 1) where cooling water enters the absorber first before the condenser, 2) where it enters the condenser first before the absorber, and 3) where it enters the absorber and condenser in parallel. The first configuration performs adequately without reaching crystallization limits, though its COP is not highest. The third configuration has the highest COP but requires almost double the cooling water, making it not economically feasible. The analysis found that reducing condenser temperature can increase COP but also increase crystallization risk. The first configuration provides an optimum balance and is the most economically feasible option.
Beer physics
1) The authors conducted an experiment to test whether the volume of carbon dioxide gas in beer varies directly with changes in temperature, as predicted by Charles' Gas Law.
2) They used a PASCO Gas Law Apparatus to measure the gas volume in samples of Henry Weinhard's beer at various temperatures between 30-100°F.
3) Their results supported the hypothesis, as the graph of temperature versus gas volume had a positive slope, indicating the two variables varied directly as temperature increased.

Heat
The document discusses the definitions and differences between temperature and heat. Temperature is a measure of how hot an object is using degrees Celsius, while heat is a form of energy transferred between objects due to a difference in temperature. Specific heat refers to the amount of heat needed to change an object's temperature by 1 degree per unit of mass, while heat capacity is the total amount of heat needed to change an object's temperature regardless of mass. Heat and temperature are related because gaining or losing heat causes an object's temperature to increase or decrease.
Coefficient of Performance Enhancement of Refrigeration Cycles
This document summarizes an experimental study that investigated enhancing the coefficient of performance (COP) of refrigeration cycles by using different condenser designs. Three condenser designs were tested in a refrigerator: the original design and two new designs (one with plain copper tubes and one with copper tubes welded to a stainless steel plate). Measurements of temperature, pressure, heat rejection, and COP were taken over time under varying evaporator loads. The results showed that the COP of the new designs increased by up to 20% compared to the original design when no load was applied. COP generally increased with higher evaporator loads. The plain copper tube design performed best, providing better heat transfer than the welded plate design.

This experiment determined the temperature profile of a vertical steel fin both experimentally and theoretically. A steel fin was placed on a heating element set to 365 K and allowed to reach steady state. Thermocouples measured the decreasing temperature profile from the base to tip of the fin. The experimental results varied slightly from the theoretical profile mainly due to errors in temperature measurements at the fin surface. Comparing the experimental and theoretical profiles showed good agreement between the two methods of analyzing the fin's temperature change.

Biomass gasification for hydrogen production
Biomass gasification can be used to produce hydrogen fuel through thermal conversion processes. Gasification involves heating biomass with limited oxygen to produce syngas containing hydrogen, carbon monoxide, and other gases. Several pathways exist to convert biomass to hydrogen through gasification. Research has demonstrated hydrogen yields of up to 60% by volume from biomass gasification using fluidized beds and catalysts. Economic analyses show biomass gasification can competitively produce hydrogen compared to natural gas reforming. With environmental and economic benefits, biomass gasification is a promising option for renewable hydrogen production.

Biodiesel is a renewable, biodegradable fuel manufactured domestically from vegetable oils, animal fats, or recycled restaurant grease. Biodiesel meets both the biomass-based diesel and overall advanced biofuel requirement of the Renewable Fuel Standard.
Biodiesel production via transesterification of palm oil
The document summarizes research into producing biodiesel via transesterification of palm oil using sodium hydroxide loaded onto alumina (NaOH/Al2O3) catalysts. NaOH/Al2O3 catalysts were prepared by impregnating alumina with sodium hydroxide solutions then calcining. The catalysts were characterized and found to have basic sites suitable for transesterification. Parameters like methanol to oil ratio, catalyst amount, temperature and time were varied to determine optimum conditions. With the optimum conditions, a 99% conversion of palm oil to biodiesel was achieved.
Bio w properties & production techniques z wallage
Zoe Wallage presents on biochar properties and production techniques. Biochar is produced through thermal decomposition of biomass via slow pyrolysis, fast pyrolysis, or gasification. These processes convert biomass into biochar, bio-oil and syngas. Biochar properties depend on feedstock and production conditions like temperature and heating rate. A case study of UEA's biomass gasification CHP plant that produces electricity, heat and modest quantities of biochar as a byproduct is discussed, demonstrating biochar production from an existing energy system. The presentation concludes that biochar yield and quality varies significantly based on production method and biomass type.

1. The document analyzes combustion and heat release characteristics of a diesel engine fueled with blends of soybean biodiesel and diesel. Soybean oil was converted to biodiesel via transesterification, producing soybean methyl ester (SOME) biodiesel.
2. Combustion tests were conducted with SOME blends (5%, 10%, 15%) using pistons with different geometries - torodial, shallow torodial, and deep torodial. The shallow torodial piston showed the best combustion characteristics, with up to 6% higher peak cylinder pressure compared to the other pistons.
3. In-cylinder pressure and heat release rate were measured. SOME blends

The use of biodiesel, the methyl esters of vegetable oils are becoming popular due to their
low environmental impact and potential as a green alternative fuel for diesel engine. With this objective,
the present work has focused on the performance and emission characteristics of diesel engine using
rice bran oil and its blends with diesel. In this investigation, the blends of varying proportions of rice
bran biodiesel with diesel (RB20, RB40, RB60, RB80 & RB100) were prepared, analyzed, and compared
the performance and exhaust emission with diesel using 5.2 kW Single cylinder, 4stroke diesel engine.
The performance and emission characteristics of blends are evaluated at variable loads and constant
rated speed of 1500 rpm and found that the performance of RB20 blend of rice bran oil gives result, that
is near to the diesel and also found that the emission CO, CO2, HC, smoke & NOX of this blend is less
than the diesel.

This document summarizes research on upgrading fast pyrolysis oil (bio-oil) derived from wood through an esterification process. Key points:
- Bio-oil was catalytically upgraded using n-butanol and Amberlyst-15 catalyst to convert acids in bio-oil to esters and remove oxygen. This improved properties like heating value and viscosity.
- Amberlyst-15 gave better results than homogeneous catalysts, avoiding a neutralization step. However, the catalyst deactivated over time due to deposition of carbonaceous material from bio-oil.
- Characterization found the catalyst surface blocked and weight loss at high temperatures, indicating deactivation. Future work will identify conditions to minimize de
