Abstract
Catalytic endothermic reactions of exo-tetrahydrodicyclopentadiene (exo-THDCP) with different zeolites were investigated in a batch reactor to increase the heat of reaction. The heat of reaction with each zeolite was calculated by the NIST SUPERTRAPP program. The conversion and product distribution were also investigated because they affected the heat of reaction. The heat of reaction of HZSM-5 was larger than those of other zeolite due to its total acid density and pore structures. It showed the highest conversion and highest composition of low molecular weight products. Because dehydrogenation can increase endothermic heat, Pt/HZSM-5 (1 wt% Pt loaded) was used in the endothermic reaction. The metal sites led the dehydrogenation of saturated hydrocarbons and increase in olefins. To increase the heat of reaction, high conversion and high yield of low molecular weight hydrocarbons and olefins are necessary. 2013 Elsevier By. All rights reserved.
