A series of Co/HY-X catalysts for Fischer-Tropsch synthesis were prepared by melting method on HY zeolites treated with different quaternary ammonium bases.The effects of different ammonium-alkaline-treated HY zeolite on Fischer-Tropsch synthesis catalyst's performance were investigated.The catalysts were characterized by nitrogen physical adsorption-desorption,X-ray diffraction,Fourier transform infrared spectrum and ammonia temperature-programmed desorption,and the catalytic performance of the catalysts for Fischer-Tropsch synthesis was tested in a high-pressure fixed bed reactor.The results showed that the conversion rate of CO increased by about 30 percentage points on the catalyst treated with tetramethylammonium hydroxide,compared with that of Co-HY without treatment.
