摘　　要：考察了水热合成反应条件对全硅 MCM-4 1结构、结晶度的影响和产物的热稳定性 .研究发现 :改变合成母液的 p H会改变 MCM-4 1的孔径大小 ;在无氧条件下高温处理的最佳温度为 6 0 0℃左右 ;所合成的全硅 MCM-4 1具有很高的比表面积、均匀的孔径和较好的热稳定性 ,可用做制备加氢脱硫催化剂的载体 .The effects of various synthesis conditions on the pore structure and the crystallinity of the obtained MCM 41 were intensively investigated. Additionally, the thermal stability of the obtained MCM 41 was tested. It is indicated that the pore size of MCM 41 can be tuned by adjusting the pH of the synthesis mixture. Heat treatment of the as synthesized material in a N 2 flow, prior to calcination in air, is an essential step for developing quality mesostructures, and the optimal temperature is about 600 ℃. It seems that the synthesized siliceous MCM 41, with extremely high surface area(>1 000 m 2/g) and a uniform pore size and relatively high thermal stability, should be excellent supports in preparing hydrodesulfurization catalysts.
