PDVB-DMF疏水改性的Fe2N催化剂费托合成反应性能研究
Study on performance of Fe2N catalyst modified by hydrophobic PDVB-DMF for Fischer-Tropsch synthesis
摘要
Abstract
Fe-based catalysts are commonly used in Fischer-Tropsch synthesis.However,the high partial-pressure water in the process can easily lead to the oxidation and deactivation of the active phase of the catalyst.Therefore,timely removal of the generated water from the catalyst surface is a key to prevent oxidation of the active phase and prolong the lifetime of the catalyst.In this work,hydrophobic agent-porous polydivinylbenzene was mixed with Fe2N catalyst.The hydrophobicity of polydivinylbenzene accelerated the water migration in local microenvironment.This strategy effectively balanced the adsorption and release of water on the catalyst surface,reduced the occupation of water on the active site,and promoted the efficient conversion of syngas.The CO conversion of Fe2N without porous hydrophobic agent was only 34.8%.The active phase was oxidized during the reaction.While CO conversion of Fe2N mixed with porous hydrophobic agent was as high as 80.2%,and no oxidation of active phase was observed after reaction.This work shows that hydrophobic polymers have excellent effects in optimizing catalyst microenvironment,improving reaction efficiency and product selectivity,and thus provides a new strategy for syngas conversion.关键词
