The production of biodiesel from palm oil using a solid catalyst waste Phapia undulate has been studied. The catalyst was prepared by calcination of the Phapia undulate shell at 900ºC for 2 hours. The catalyst was characterized byFTIR,XRDand XRF methods.Different reactionparameters wereemployed in order to obtain maximum yield of biodiesel. The Characterization of biodiesel includes the analysis ofviscosity, density, flashpoint, cetane number, and the content of FAME using GC. The optimum parameter for maximum yield of biodiesel are palm oil /methanol mole ratio 1:8, catalyst content 4% wt, reaction time 5 hour, with constant temperature of 60ºC and rate of mixing 700 rpm. © Research India Publications.
