Abstract
Co基催化剂因具有高活性和强链增长能力等优势,成为费托合成(FTS)反应适宜的催化剂.总结了Co基催化剂FTS反应机理,并对活性相结构以及助剂与催化性能的构效关系进行了分析.同时,围绕催化剂载体的作用,总结金属-载体相互作用促进FTS反应性能的研究进展,重点分析了金属Co与分子筛耦合直接合成液体燃料的研究进展,归纳了采用双功能催化剂体系制备液体燃料的反应路线及催化剂特征.
Cobalt-based catalyst is regarded as a suitable choice for Fischer-Tropsch synthesis(FTS)due to its high activity and strong C—C bond formation ability.FTS reaction mechanism of Co-based catalysts was summarised,and the structure of the active phase as well as the conformational relationship between additives and catalytic performance were analysed.For clarifying the role of catalyst supports,the promotion of FTS reaction via regulating metal-carrier interaction was also summarized.Specially,the direct synthesis of liquid fuel by coupling metal Co with zeolite catalyst was discussed,and the reaction route for liquid fuel and the character of as-used bifunctional catalyst were focused.
