Fabrication and catalytic tests of MCM-22/silicon carbide structured catalysts.
The structured catalyst of zeolite MCM-22/silicon carbide (SiC) was prepared for the first time through the in situ hydrothermal synthesis approach. The zeolite loading of the structured catalyst could be tuned by changing the synthesis time and applying alkali pre-treatment of SiC substrate. An additional silica layer formed on SiC substrate after the precalcination treatment facilitated the crystallization of MCM-22 zeolite on the SiC substrate. The MCM-22/SiC structured catalyst thus prepared exhibited good catalytic performance in the methane dehydroaromatization reaction.
