英文摘要Direct synthesis of liquefied petroleum gas (LPG) from syngas over hybrid catalysts consisting of methanol synthesis catalyst and Pd-modified zeolites such as Pd/SAPO-11, Pd/ZSM-5, Pd/beta, and Pd/Y was investigated in a fixed-bed reactor. Pore diameter of zeolites had great effect on LPG selectivity. The hybrid catalyst composed of methanol synthesis catalyst and Pd/Y demonstrated a good reactivity and more than 73% selectivity for LPG at 300 degrees C, 2.1 MPa, and the space velocity of 1 500 h(-1). N-2 adsorption-desorption, NH3 temperature-programmed desorption and temperature-programmed oxidation were carried out to study the properties of the catalysts before and after reaction. The results indicated that coke deposition was the main reason for the catalyst deactivation.
