SINTESIS KATALIS PADAT SO4 2- / TiO2 DENGAN METODE IMPREGNASI DAN APLIKASINYA PADA METANOLISIS MINYAK JELANTAH

Abstract

This research relates to the utilization of cooking oil waste as a source of raw material for biofuel throughmethanolysis reaction using heterogeneous / solid SO42- / TiO2 catalysts. The long-term goal to be achieved is the masteryof biofuel production technology by utilizing waste or used cooking oil and using catalysts that are environmentallyfriendly and economical so that they can contribute to increasing national energy security. The research activity beginswith the synthesis of catalysts by impregnation method, then followed by chemical reactions methanolysis. The SO42- /TiO2 catalyst diffractogram shows that at position 2θ = 26â° there is a peak with the highest intensity. This indicates thatTiO2 is in the anatase phase. Besides that the success of synthesis can be seen in FTIR spectrum where sulfate ionscoordinated with Tiâ´âº metal cations are shown on the appearance of absorption peaks of 1250.96, 1150.96 and 1098.68cmˉ¹. Catalyst performance has been tested by identifying product composition using GC-MS and acid base titration. Thecomponents of product are classified as C9H14O2 short carbon chain fatty acids, C3H4 aliphatic compounds, and C18H36O2palmitic acid ethyl ester.
