Distribution between C2 and C3 in low temperature Fischer–Tropsch synthesis over a TiO2-supported cobalt catalyst

Experimental analysis and preliminary assessment of an integrated thermochemical process for production of low-molecular weight biofuels from municipal solid waste (MSW)

“…The synthesis of liquid hydrocarbons from syngas via FT is a well-known process already under use throughout the world in coal and natural gas-based (CtL, GtL) plants. However, the output of LMW hydrocarbons from this process is relatively small, at a few per cent of the total hydrocarbons output [63]. In fact the strategy selected by current commercial FT plants has been to maximise thermodynamically the production of C21+ fraction (wax) via low temperature FT synthesis, minimising the formation of undesired light products.…”

“…An increase in the H2:COx ratio strongly increases the reaction rate, as well as the paraffin selectivity. This will be a function of an increase in hydrogen surface coverage and the positive equilibrium effects that increases in H2 partial pressure have on the FT reaction which are known to cause higher methane and paraffins production [63], [64]. In addition, an increasing H2:CO molar ratio has been reported to improve the exothermic heat removal in the reactor and enhance the catalyst life and activity as carburisation (or coke formation) on the catalyst surface is minimized [80].…”
