The Fischer–Tropsch process involves a series of chemical reactions that produce a variety of hydrocarbons, ideally having the formula (C n H 2n+2).The more useful reactions produce alkanes as follows: (2n + 1) H 2 + n CO → C n H 2n+2 + n H 2 O. where n is typically 10–20. The formation of methane (n = 1) is unwanted.Most of the alkanes produced tend to be straight-chain, suitable as .
