Abstract

The effect of the means used to synthesize bifunctional cobalt catalysts with HZSM-5 zeolite and a boehmite binder on the catalytic performance of Fischer–Tropsch (FT) synthesis is studied. The synthesized catalysts are characterized via BET, XRD, EDA, SEM, TEM, H₂ TPD, and NH₃ TPD. They are tested in hydrocarbon synthesis at a pressure of 2.0 MPa, a temperature of 240°C, and a gas hourly space velocity of 1000 h⁻¹. It is shown that the hydrocarbon and fractional composition of the FT synthesis products can be controlled, depending on the means of catalyst synthesis. A promising composite catalyst system for the single-stage synthesis of a low–pour-point diesel fuel has been proposed.

双功能费-托催化剂合成方法对合成燃料组成和性能的影响

摘要

研究了用HZSM-5沸石和勃姆石粘合剂合成双功能钴催化剂的方法对费托合成的催化性能的影响。合成的催化剂通过BET，XRD，EDA，SEM，TEM，H ₂ TPD和NH ₃ TPD进行表征。它们在2.0 MPa的压力，240°C的温度和1000 h ^-1的气体时空速度下进行了烃合成测试。结果表明，根据催化剂合成方法，可以控制FT合成产物的烃和馏分组成。已经提出了一种有前途的低催化剂柴油单级合成催化剂体系。
