Abstract: Recently, non-edible oil based biodiesel fuels have more attractive among all researchers as well as government than edible sources based alternative fuels. The objective of this study is to compare the engine performance and emission results of biodiesel produced from Jatropha oil when applied in different proportions in multi cylinder diesel engine. Results revealed that biodiesel blends produce less CO (up to 52.6%) and lower HC (up to 48%) with an increase in emission of NO (up to 11.82%). Biodiesel also presented a slight increase in brake specific fuel consumption (up to 8.33%) which may be acceptable considering the reduction in exhaust emissions. The experimental results proved that biodiesel blends can be used in compression ignition engines, thereby providing a viable alternative to diesel.

Abstract: The use of aqueous suspension of nanoparticles of titanium dioxide for photocatalytic removal of pollutants is not suitable for industrial applications due to the inconvenient and expensive separation of nanoparticles of titanium dioxide for reuse. The nanosized titanium dioxide needs to be immobilized on the support for improving the efficiency and economics of the photocatalytic process. In the present paper, nanoparticles of titanium dioxide have been immobilized on the surface of the support using three different techniques. The immobilized films of titanium dioxide have been characterized using X-ray diffraction to ascertain any change in the phase composition and photocatalytic properties of the titanium dioxide after immobilization on the support. A photocatalytic test has been performed under similar reaction conditions tocompare the photocatalytic performance of the films of immobilized titanium dioxide prepared using different techniques.
