SAPO‐34 is a crystalline microporous material, the characteristics of which are greatly influenced by synthetic parameters, especially the silica precursors and templates. In this study, the combination of templates and silica sources was optimized to obtain SAPO‐34 phases in the purest form. The physicochemical properties of the thus‐synthesized catalysts were characterized, and the Si environment in the SAPO‐34 framework was analyzed. The catalytic performance in biomass gasification was investigated in a fixed‐bed flow reactor. SAPO‐34 synthesized with triethylamine/morpholine/tetraethylammonium hydroxide templates exhibited the highest total acidity, the smallest particle size, and high surface area, and produced a large amount of light hydrocarbons in biomass gasification.

结合模板气化生物质合成Zeotype SAPO-34

SAPO-34是结晶微孔材料，其特性受合成参数（尤其是二氧化硅前体和模板）的影响很大。在本研究中，对模板和硅胶来源的组合进行了优化，以获得最纯净形式的SAPO-34相。表征了由此合成的催化剂的物理化学性质，并分析了SAPO-34骨架中的Si环境。在固定床流动反应器中研究了生物质气化的催化性能。用三乙胺/吗啉/四乙基氢氧化铵模板合成的SAPO-34表现出最高的总酸度，最小的粒径和高的表面积，并在生物质气化过程中产生了大量的轻烃。
