The Fischer-Tropsch production of organic molecules

The catalyst is typically iron, which is promoted by dre addition of copper, Si02 and an alkali oxide, usually K2O. The catalyst can be prepared by 

The weight fraction can be calculated by multiplying each remaining fraction by wi, where wi is the molecular weight of the monomer, then for the nth species 

Data from die results of an industrial reactor study produced the result a — 0.606 + 0.012  

The effect of increasing pressure is to move the average hydrocarbon content towards the heavier species, but increasing temperature seems to favour the production of lighter species. The final proportions are also determined by the state of the catalyst, and the physical anangement of tire reactor. The formation of the oxygenated compounds could also involve reactions between the H2O content of tire gas in the form of adsorbed OH radicals and hydrocarbon radicals since the production of these molecules is also well beyond the thermodynamic expectation.
