Preparation of Pd/Al-MCM-41 Catalyst and Its Hydroisomerization Properties for long chain alkane compounds

摘要

The mesoporous material Al-MCM-41 with various Si/Al ratios was synthesized rapidly by microwave under acidic conditions using cetylpyridinium bromide (CPBr) as template and tetraethylorthosilcate (TEOS) as silica source. The hydrogen forms of Al-MCM-41 were obtained via ion exchange. Pd/Al-MCM-41 catalysts were prepared by impregnation method. The catalytic activity and selectivity of as-synthesis catalysts for tridecane hydroisomerization were also evaluated.
