介孔分子筛在长链正构烷烃异构化中的研究进展

介绍了长链正构烷烃异构化的催化剂,并着重探讨了介孔分子筛催化剂在这方面的研究进展。随着对介孔材料的不断研究,许多人从不同的合成路径和操作条件出发,合成出了多种不同组分及结构的介孔分子筛催化剂,并对有规则孔结构的介孔催化剂进行了改性,结果表明改性后的介孔催化剂对长链正构烷烃异构化具有较好的催化活性和选择性。其中一些研究成果在石油炼制和石油化学工业领域得到了广泛的应用。

Progress in Mesoporous Catalysts for Isomerization of High n-Alkanes

The catalysts for selective conversion of high n-alkanes into their branched isomers were introduced, particularly the mesoporous materials. With the development of mesoporous materials, many kinds of mesoporous materials with different components and structures were synthesized by different cooperative assembly pathway and at different synthesizing conditions. The ordered mesoporous catalysts were modified, and were testified with good activity and selectivity for selective conversion of high n-alkanes into their branched isomers. Some of the results have been applied in the oil refining and petrochemical industries.
