Pemanfaatan Sekam Padi sebagai Katalis Zeolit ZSM-5 Mesopori melalui Metode Sintesa Double dan Bebas Template untuk Konversi Metanol

Abstract

Rice husk is an abundantly available agricultural waste material containing maximum amount of siliceous
ash. Burning of rice husk in air produces rice husk ash containing 85-98 % silica. In this research, rice husk
ash and coal fly ash were used as raw materials for catalyst of ZSM-5 zeolite synthesis. Coal Fly ash was
added to adjust the source of alumina. ZSM-5 zeolite was synthesized through hydrothermal treatment using
double templates (TPAOH and PDDA) and free template. The as-synthesized ZSM-5 was then characterized
using FTIR, XRD, SEM-EDX, and BET. From the result of characterization, ZSM-5 has been success to be
synthesized from rice husk ash. After ZSM-5 was synthesized, the catalytic activities of ZSM-5 were tested to
convert methane to methanol. The result showed that catalytic activity of ZSM-5 double template on
methanol convertion was 7.08 % and free template was 10.54 %. It means, rice husk ash was potential to be
used as catalyst for the conversion of methane to methanol.
