中文摘要：
在水热条件下合成了包覆型MCM-41-HY复合分子筛，采用XRD、N2气吸附和SEM等方法对其进行了表征．结果表明，MCM-11-HY复合分子筛和MCM-41与H型Y沸石（HY）的机械混合物明显不同，在复合分子筛MCM-41-HY中．中孔相MCM-41附晶生长在HY沸石上，将HY包覆起来，以二苯并噻吩为模型化合物，考察了该材料担载NiMo催化剂的加氧脱硫活性．结果表明，MCM-41-HY复合分了筛与MCM-41和HY的机械混合物担载NiMo催化剂的加氯脱硫（HDS）活性相当，但MCM-41-HY复合分子筛担载NiMo催化剂的裂化活性较低．其裂化活性不同的原因在于其载体孔道结构和酸性位的分布不同。
英文摘要：
MCM-41-HY composite molecular sieves were synthesized hydrothermally, and characterized by means of XRD, N2 adsorption and SEM. A comparison was made between the mechanical mixture of MCM-41 and HY, and the synthesized MCM-41-HY composite molecular sieves as the hydrodesulfurization（HDS） catalyst support. Both exhibit excellent activities in the HDS hydrodesulfurization of dibenzothiophene, but, the composite shows a much lower hydrocracking activity than the mechanical mixture. It is proposed that the lower hydrocracking activity of MCM-41-HY composite molecular sieves may be attributed to the bimodal structure in which HY zeolite is wrapped by the mesoporous MCM-41.
