摘要：

Hybrid catalysts in a double-layered bed reactor were used to produce light C-2-C-4 paraffin hydrocarbons. Combinations of Fischer-Tropsch (FT) and cracking catalysts in a double-layered bed reactor configuration were studied. SAPO-34 and Ni-based cracking catalysts (hybrid catalyst) were used to convert C-5(+) into CH4 and C-2-C-4 paraffin hydrocarbons. Activity tests in the double-layered bed reactor at 10 bar and 300 degrees C and using a H-2/CO feed gas ratio of 3.0 revealed that the hybrid catalyst showed lower C-5(+) and higher CH4 and C-2-C-4 selectivities than the FT catalyst alone. The Ni-based catalyst enabled additional CO conversion and CO2 methanation.
