Abstract

The use of renewable fuels is an alternative for the Indonesian government in addressing the problem of the energy conservation and environment. One of the keys to the success of the renewable fuel manufacturing process in the cracking method is the type and composition of the catalyst. This study conducted a performance test of Zn HZSM-5/-alumina (1:1) and (1:2) catalysts for stearin cracking. The reaction test was carried out at 350 to 450 ⁰C with an increase in temperature of 25 ⁰C. Stearin catalytic cracking was carried out in a fixed bed reactor that had been filled with catalysts. Stearin cracking results in a mixture of products in the vapor phase. The product was pushed and flowed through the condenser. In the condensation process a mixture of liquid and solid were produced. The liquid product was separated from the solid product, then its composition was analyzed using GC-MS. The results showed that the Zn-HZSM-5/-alumina catalyst (1:1) and (1:2) can be used for cracking stearin to produce biofuels. Catalyst of Zn-HZSM-5/-alumina (1:1) is better than Zn-HZSM-5/-alumina (1:2) in producing products. The highest liquid yield of 26.40 wt% is obtained when the cracking process is carried out at 450 ⁰C using a catalyst of Zn-HZSM-5/-alumina (1:1).
