核壳结构Cr-Zn@SiO2@MSAPO催化剂的制备及协同催化生物质热解气合成低碳烯烃研究

Preparation of Core-Shell Structure Cr-Zn@SiO2@MSAPO Catalyst and Study on Synthesis of Low Carbon Olefin from Biomass Pyrolysis Gas

环境污染和能源危机已经成为当今社会面临的两大挑战,而生物质热解气在解决上述两个问题方面有重要的应用价值。新型核壳结构Cr-Zn@SiO2@MSAPO催化剂利用其特殊的"氧缺陷"活性位点和限域催化效应,使合成气进行新型费托催化转化过程,实现合成气向低碳烯烃的高效转化。本实验基于生物质热解气与合成气组成成分的相似性,实现生物质深度催化热解所得热解气为原料,再经新型费托催化合成技术将热解气转化为重要的工业原料(低碳烯烃)。

Environmental pollution and energy crisis have become two major challenges facing the society, and biomass pyrolysis gas has important application value in solving the above two problems.The new core-shell structure cr-zn-@sio2-@msapo catalyst utilizes its special "oxygen defect" active site and limited catalytic effect to make the synthesis gas undergo the new fetter-catalyzed conversion process and realize the efficient conversion from the synthesis gas to the low carbon olefin.This experiment based on biomass pyrolysis gas and the composition of the syngas similarity, realize the depth of the biomass catalytic pyrolysis the pyrolysis gas as raw material, then through fischer-tropsch catalyst in synthesis of new technology will pyrolysis gas into the important industrial raw material(low carbon olefin).
