Abstract
The Catalytic convertion of Jatropha oil to liquid fuel over various type has been studied. The active groups of Jatropha oil trigliseride giving occasion to polymerisation and polycondensation reaction. In this research, Jatropha oil was mixtured by water to neutralize or stabilize the active group of Jatropha oil by Hydrolysis Reaction to produce Fatty Acid and Glycerol . Feed ratio was variated to get optimum ratio. The reaction was conducted in a fixed bed reactor at atmosferic pressure and temperature 400-500oC over B2O3/Zeolite catalyst. The maximum gasoline fraction yield of 19% with gasoline selectivity of 40,6% was obtained with 20% B2O/Zeolite, at 500oC, and feed ratio 1:1 (weight water/oil).
