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,考察了不同季铵碱处理对Co/HY催化剂性能的影响。采用N2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,在季氨碱处理后的Co基催化剂作用下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。

Abstract: 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 catalysts 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.

Key words: HY zeolite, Fischer-Tropsch synthesis, cobalt-based catalyst
