Direct Alcohol Electro-oxidation in an Intermediate Temperature Fuel Cell

Abstract: Anodic reactions in a direct alcohol fuel cell (DAFC) at intermediate temperature (250 oC) were investigated from the standpoint of achieving high performance. In order to evaluate the temperature effect on the electro-oxidation of small alcohols in the intermediate temperature region, a kinetic study on the electro-oxidation of methanol and ethanol on Pt/C was conducted using a single cell fabricated with CsH2PO4 proton conducting solid electrolyte. At 250 oC, the current density of ethanol electro-oxidation is comparable to that of methanol electro-oxidation in a low potential region (< 400 mV vs. RHE). In addition, the analysis of reaction products suggests that C-C bond cleavage in ethanol electro-oxidation can proceed at the intermediate temperature. Through the electrochemical measurements, characteristic features in the alcohol electro-oxidation at the intermediate temperature were discussed.

Production of alcohol fuel

Abstract: Alcohol fuel can be produced by: treating raw materials, fermenting, refining, molecular sieve adsorption dewatering, and waste liquid treating. A thermal coupling is used to connect dewatering and condense distilling procedures, i.e., gas alcohol from refining process is fed to molecular adsorption dewatering process after thermal coupling condensation and distillation. Heat energy released from cold condensation is used as heat energy for distillation. None of energy is needed any more. The raw materials may be corn, rice, wheat, Chenese sorghum, dry sweet potato, cassawa, sugarcane juice, sugarbeet juice, or green cyrup, etc.

Dissolving Oxygen in Diesel Fuel as a Way to Make Road Transport More Environmentally Friendly

Abstract: This paper on dissolving oxygen in diesel fuel is from the proceedings of 14th international Conference on Urban Transport and the Environment in the 21st Century, which was held in Malta in 2008. The authors reports on a recent development that uses an improved mechanism of spray to fuel diesel engines; the new spray consists of dissolving air, exhaust gases or oxygen in diesel fuel. This process has a volumetric character and at the appropriate kinetics it is strong enough to be accompanied by the effervescence (bubbling) of the liquid. This paper presents the results of tests demonstrating the impact of oxygen dissolved in diesel fuel on the combustion process in diesel engines. The tests were done in the piston head of an engine equipped with a toroidal combustion chamber and direct injection. The tests measured the main indicators of motor operation, the range of pressure values obtained in the combustion chamber and before the injector, emissions of HC, CO2, CO, NOx, and opacity. The test results show that this new mechanism of fuel spraying can reduce emissions, particularly toxic compounds and carbon dioxide. In addition, fuel disintegration is more efficient with this type of fuel spraying.

Development of the Premixing Injector in Burner System

Abstract: Today, global warming is the biggest issues due the increasing of emissions from diesel fuel in transportation and manufacturing sectors [1-. The solution for this issue is by using Biodiesel fuel as alternative fuel in both sectors. Malaysia government has introduced the Biodiesel (B5) in the diesel engine for transportations [3]. Biodiesel fuel (BDF) in alternative fuel and renewable energy but it has low quality of fuel and can reduce the performance compared to the diesel fuel (DF)[4-6].
