PERFORMANCE OF ALKALI-TREATED HY ZEOLITE SUPPORTED Co-BASED CATALYST FOR FISCHER-TROPSCH SYNTHESIS

Abstract

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
