Abstract
A demonstration examination was conducted to establish a technology for producing high quality biodiesel fuels consisting of olefin and paraffin from the waste food oils in the catalytic cracking method in which the newly developed catalyst is applied. A demonstration facility having a waste food oil processing capacity of 5L/h, and consisting of a catalytic reactor and fractionators was designed and constructed. Then the examination has led to an achievement of a biodiesel yield of approx.60% in weight and 67% in heat (calculated at 87% in heat when other components are included). Moreover, the quality of the biodiesel fuel complied with all regulations in the diesel fuel quality standards. A chassis dynamometer test in EC mode was conducted using a common rail engine vehicle. The fuel was a light oil blended with biodiesel fuel in content of 30%. The blended fuel was on a par with a commercially- available light oil in terms of fuel consumption rate, NOx emission and PM emission
