Effects of ambient temperature condition on biodiesel properties derived from palm oil.

Abstract

Crude palm oil (CPO) is currently the most preferable feedstock to be converting into biodiesel via transesterification process in this region. Though the commercial projections for biodiesel have grown, there remains some concerns with respect to its resistance to degradation during storage that possibly will compromise the fuel quality. The purpose of this study is to investigate the influences of ambient temperature condition on properties of biodiesel characteristics and emission. The biodiesel samples were stored and monitored in glass container at the temperature 6??C, 25??C and 30??C, and blending of biodiesel was varied from 5vol% (B5) - 45vol% (B45). The changes of density, kinematic viscosity, flash point, water content, acid value, and as well as emission of C02 and CO were observed. The result show storage under ambient temperatures properties of CPO biodiesel were found to have higher value compare to the other temperature storage and also have significant effect on the CO emission.
