Abstract
Fischer-Tropcsh synthesis is a catalyzed chemical reaction in which synthesis
gas, a mixture of carbon monoxide and hydrogen, is converted into liquid hydrocarbons
of various forms. The most common catalyst used in the synthesis are cobalt and iron. In
this project colloidal method approach is used to synthesize mono dispersed iron silica
based nanocatalyst. The iron loading was kept at 6 wt%. The nanocatalysts are then
characterized by using FESEM and TPR. There are several parameters are taken into
account in order to produce a uniform distribution iron on the silica support which are
aging time, temperature and ratio between surfactant and precursor.
