文摘

Some CO2 in syngas can increase the conversion of FT process with an iron catalyst. Overall thermal efficiency for biomass to FT liquids was in a range of 41.3–45.5% A reformer to recycle off-gas improves the economics for maximum FT fuel production. Co-feeding of natural gas as 50% energy input reduces 30% costs of FT liquids. It is not economically feasible to produce FT biofuels at oil price of $60/barrel.
