A study has examined the conversion efficiency of cobalt containing catalysts (Co catalysts) made from layered double hydroxides for synthesis of hydrocarbons from carbon monoxide and hydrogen, the so called Fischer-Tropsch synthesis. The proposed synthesis is the second and important step of production of synthetic motor fuels from nonpetroleum feedstock, natural or casing-head gas, coal, combustible shales, and biomass of varying origin. The process is increasingly drawing attention as cost of crude oil and petroleum in the world market has risen. The catalysts efficiently converts a mixture of carbon monoxide and hydrogen into the most valuable products-liquid and solid C 5+ paraffin. The heat treatment temperature and the method of preparation greatly impart in determining the catalyst's activity and selectivity. Findings suggests that the use of the synthetic hydroltalcites can better support catalyst's efficiency for proposed synthesis.
