Al2o3 Catalyst

The attractiveness of biodiesel as an alternative fuel compared to fossil fuels because it has many advantages such as the availability of abundant raw materials, more environmentally friendly, high combustion efficiency, low sulphur content, high cetane number and biodegradability. Making biodiesel from straight vegetable oil (VGO) has been done through the catalytic hydrogenation process. A VGO of callophylum inophyllum oil was treated via degumming and neutralisation to remove all impurities before hydroprocessing. Hydroprocessing was carried out in a 500ml autoclave at 30 – 50 MPa of initial hydrogen pressure, 300 – 400oC of reaction temperature and equipped with stirrer and cooling system. NiMo/Al2O3 catalyst was activated with CS2 mixture at 370oC prior to the reaction. Some physical and chemical properties of the catalytic hydroprocessing product have been investigated in accordance to ASTM standard. The measurement result of product varies according to the operation condition. The result showed that callophyllum inophyllum oil can be used as raw material for biodiesel production over NiMo/Al2O3. Sulfided NiMo/Al2O3 catalysts are preferred due to high diesel yield.

This study reports an ongoing effort to investigate the degradation rate of a low-speed Listeroid diesel engine running on filtered waste vegetable oil (WVO). It aims to measure the performance, wear rate, and emissions of the engine over the course of a 1,000 hour longevity test. In a consecutive arrangement, exhaust gas is used to heat the oil, reducing its viscosity close to that of diesel for the duration of the residence time in the fuel line. This reduces engine power loss, pumping losses, head losses, carbonization and coking, which ultimately increases longevity. When completed, the technical methods developed, data collected, lessons learned, and hardware used will all be incorporated into a manufacturable, stand-alone, cost-efficient, field conversion kit for the Listeroid engine. The results of this study will be beneficial in actualizing the widespread and practical use of WVO and straight vegetable oil (SVO) fuels in developing countries.
