摘　　要：以不同季铵碱处理后的HY分子筛为载体,通过熔融法制备了Co/HY-X系列催化剂,并用于费-托合成反应,考察不同季铵碱处理对Co/HY催化剂性能的影响。采用N_(2)吸附-脱附、X射线衍射、傅里叶变换红外光谱和氨程序升温脱附等手段对催化剂进行表征,并在高压固定床反应器上对催化剂的费-托合成催化性能进行测试。结果表明,与未经过季铵碱处理的Co/HY相比,在季铵碱处理的Co基催化剂作用下的CO转化率都有所提高,其中经过四甲基氢氧化铵处理的Co/HY催化剂性能最好,CO转化率提高了约30百分点。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.
