| Descripción : | Si-Al, Si-Ti and Si-Mg supports were synthesized by sol-gel method and evaluated in the cumene reaction. Acid-base properties of the supports those were determined by using 2-propanol reaction into propene and acetone, which allow to know quantitatively the support properties. The supported catalysts were prepared with NiMo, NiW and CoMo by the incipient wetness method. In addition, the supported catalysts were evaluated for cumene cracking and its kinetic parameters were obtained by applying the Langmuir-Hinshelwood model. The activation energy was 27.75 kcal mol-1 and the heat of absorption calculated with the Van’t Hoff equation was 14.15 kcal mol-1. Si-Al supported NiMo catalyst were found more active in cumene cracking most probably due to its stronger acidity generated during the support preparation. Instituto Politecnico Nacional |
