Abstract Currently, cobalt and zeolites are used in Fischer-Tropsch synthesis (FTS) to produce gasoline-range hydrocarbons (GRHs) that constitute clean and environmentally friendly fuels. This technology has earned a great deal of attention from researchers across the world, as it provides a substitute for fuel derived from fossil crudes, which have hitherto been the sole source of the petrol and diesel required by the industry. However, owing to the depletion of the earth’s oil and coal reserves and the unfavourable environmental impact of conventional fuel production, an alternative source of fuel is needed. This article provides a critical review of the technological challenges involved in producing middle isoparaffins and olefins (gasoline hydrocarbons) by FTS. These involve combining cobalt-based catalysts and zeolites to form hybrid catalysts. In this review, we address most of these by setting out each method of creating cobalt and zeolite hybrid catalysts in turn, so that researchers can identify which applications are most effective for producing GRHs.

费托合成中的钴杂化催化剂

摘要 目前，钴和沸石用于费托合成 (FTS) 以生产构成清洁环保燃料的汽油级碳氢化合物 (GRH)。这项技术赢得了世界各地研究人员的极大关注，因为它提供了一种源自化石原油的燃料替代品，迄今为止，化石原油一直是该行业所需的汽油和柴油的唯一来源。然而，由于地球石油和煤炭储量的枯竭以及常规燃料生产对环境的不利影响，需要替代燃料来源。本文对通过 FTS 生产中间异链烷烃和烯烃（汽油烃）所涉及的技术挑战进行了批判性回顾。这些包括将钴基催化剂和沸石结合以形成混合催化剂。在这篇综述中，我们通过依次列出制造钴和沸石混合催化剂的每种方法来解决其中的大部分问题，以便研究人员可以确定哪些应用对生产 GRH 最有效。
