Abstract: There is provided a method for producing hydrocarbon compounds. The method comprising: producing a syngas by introducing a fuel stream comprising a reformable fuel into a reforming system (steam reformer, autothermal reformer, cold plasma reformer and/or internal-reforming fuel cell), and wherein the syngas comprises H2, CO and CO2, and has a ratio of [H2]/[CO] of about 1.4 to about 2.5; producing a decarbonated and dehydrated syngas from the syngas having a ratio of [CO2]/[CO+CO2] of no higher than 0.6; performing a Fischer-Tropsch synthesis on the decarbonated and dehydrated syngas in the presence of a cobalt- or iron-based Fischer-Tropsch catalyst, said Fischer-Tropsch catalyst comprising pellets of trilobe, cylindrical, hollow cylinder or spherical construction with diameter about 0.5 mm to about 3.0 mm and aspect ratio of 1 to 3.5, to produce a product stream comprising the hydrocarbon compounds; and recycling aqueous products and/or tail gas.
