Fischer-Tropsch synthesis is a polymerization reaction which produces various
products such as paraffin, olefins, alcohols, and aldehydes. The purpose of this study was to
determine the performance of Fe and Co bimetallic catalysts with the support of HZSM-5 for
Fischer-Tropsch synthesis. This study consists of two stages. The first stage was started by
making a mesopore sized HZSM-5 catalyst through desilication, then impregnated with
bimetallic Fe and Co which acted as a promoter. The impregnation method used was the incipient
wetness impregnation. In the impregnation, process variations were made in the ratio of Fe to
Co 1:9 and 2:8 metal loading was 10%. The Fe-Co catalyst / HZSM-5 was analyzed for
characterization and activity tests. The characteristic tests were BET, XRD, FTIR, and EDX.
The second stage was activity test of Fe-Co / HZSM-5 catalyst in the biofuel production process
from syngas through Fischer-Tropsch reaction: The best performance catalyst was used for the
biofuel production process. Fischer-Tropsch process was carried out in a fixed bed reactor, with
an operating temperature of 200, 225, 250C carried out for 100 hours in one run, then analysis
of product composition by GC-MS
