STUDI AWAL PADA PREPARASI KATALIS BERBASIS LEMPUNG BERPILAR UNTUK REAKSI ETANOL MENJADI GASOLINE (ETG)
Abstract: Research on
catalytic reaction of ethanol to gasoline (ETG) was investigated in this study.
The catalyst with a high acidity is required for the ETG reaction. Therefore,
this study focused on the catalyst preparation of ETG reaction by using natural
clays which prepared by the pillarization techniquewithseveral metal oxides,
such as:AI, Zr, Fe and Cr as the pillared. The prepared of pillared clay were
characterized by x-ray diffraction, specific surface area and pore distribution
(BET) measurements and catalytic
activity testing on the ETG reaction. It is observed that after the
pillarization; the surface area and basal spacing (d001) of the natural clays
were significantly increased. thus the
ptllarization process was successfully prepared on natural clay.
However,the acidity of theprepared ofpillared clay is still lower,probably due to the cations between
layers of the natural clay were not homogeneous, thus although the
pillarization process was happen but still not completely. Moreover, IR
measurement showed only the acid type of Lewis is increased after the
pillarization. Thistype is not favorable for the ETG reaction, and thus only
the lower hydrocarbon products (<Cl2) were observed after the ETG reaction,
even aromatics and cyclic hydrocarbon compounds wereobtained
