Abstract

The study investigates the effects of nickel introduction methods on the properties of a hybrid cobalt catalyst in a combination of Fischer–Tropsch synthesis and the hydroprocessing of the synthesized products. At 240°C, 2 MPa, and syngas WHSV 1000 h–1, the catalytic performances were compared, the products were analyzed for the hydrocarbon and fractional compositions, and the characteristics of the synthesized fuels were determined. Among the catalysts differing in nickel introduction method, the sample with a nickel-containing zeolite component prepared by ion exchange was found to have the highest hydrogenation activity, while the sample with a metal component generated by joint cobalt/nickel introduction [Co/SiO2 + Ni(i)/HZSM-5 + Al2O3] exhibited the highest isomerization activity.

摘要

该研究调查了费托合成和加氢处理合成产物中镍引入方法对混合钴催化剂性能的影响。在240°C,2 MPa和合成气WHSV 1000 h –1的条件下,比较了催化剂的催化性能,分析了产物的烃和分馏组成,并确定了合成燃料的特性。在镍引入方法不同的催化剂中,发现具有通过离子交换制备的含镍沸石组分的样品具有最高的氢化活性,而具有通过钴/镍联合引入产生的金属组分的样品[Co / SiO 2 + Ni(i)/ HZSM-5 + Al 2 O 3表现出最高的异构化活性。
