摘要：

The catalytic performance of Cu-ZnO/Pd-beta catalyst for syngas to LPG (Liquefied Petroleum Gas) has been investigated in this paper. The kind of zeolite, SiO2/Al2O3 ratio in Pd-beta, Pd-beta particle size, Pd content in Pd-beta, and reaction conditions, have been optimized. The results showed that the suitable reaction conditions for syngas to LPG over Cu-ZnO/Pd-beta are: 325-350 degrees C, 2.1-3.6 MPa, 4.5-9 g h/mol gas velocity (W/F), and 37-75 ratio of SiO2/Al2O3. At the optimal conditions, Cu-ZnO/Pd-beta could exhibit ail excellent catalytic performance for syngas to LPG: 72.2% CO conversion, 45.3% hydrocarbon yield and 78.0% LPG selectivity in hydrocarbons could be achieved.
