Abstract


Catalysts NiMoP/γ-Al O -B O have been successfully synthesized by impregnation method. The 2 3 2 3
catalyst was developed to process of vegetable oil hydrodeoxygenation (HDO). The effect of the
addition of boron and phosphorus on the activity and selectivity was studied in this research . In
addition , the determination of appropriate operating conditions were also studied in order to obtain
products with good conversion and selectivity. The research was conducted on the preparation of the
hydrodeoxygenation catalyst , test the activity and selectivity of hydrodeoxygenation catalysts, and
catalysts characterization using BET , XRD and AAS . To determine the performance of the catalyst ,
the hydrodeoxygenation catalysts were tested their activity and selectivity which took place in a batch
reactor at a pressure of 20-60 bar and a temperature of 320-360 ° C. The composition of products were
analyzed by using a Gas Cromatography . From the implementation of HDO reaction of vegetable oil
with NiMoP( 0.6 % )/γ- Al O - B O (1.7 %) catalyst, the value of conversion obtained was 81.45 % at 60 2 3 2 3
o bar operating pressure conditions and temperature 360 C .
Keywords: vegetable oil , hidrodeoksigenasi , catalyst Nimo - γalumina
