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