Catalytic endothermic reactions of exo-tetrahydrodicyclopentadiene with zeolites and improvement of heat of reactions
چکیده انگلیسی


• Heat of reaction from endothermic reaction of exo-tetrahydrodicyclopentadiene with zeolites was investigated.
• Conversion and product distribution affected heat of reaction.
• It is need to lead high conversion and high yield of low molecular weight hydrocarbons and olefins to increase heat of reaction.

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.
