METAL CATALYST FOR DEHYDROGENATION WITH CONTROLLED CRYSTAL CHARACTERISTICS OF ZINC OXIDE AND ALUMINA

摘要

PURPOSE: Provided is a metal catalyst for dehydrogenation in which crystal characteristics of zinc oxide and alumina are controlled and their specific composition rate is prepared during the heat treatment. The catalyst has highly selective production rate of olefin and stably dehydrogenates. CONSTITUTION: The metal catalyst for dehydrogenation is characterized in that a carrier that is represented by ZnxAl2Oy (x is 0.01-0.57, y is 3.01-3.57, specific surface area is 40-140m¬2/g) is supported with 0.1-2 wt.% of platinum. In the metal catalyst, Zn is contained in the metal catalyst in an amount of 1 to 35 wt.%, and the weight ratio of ZnAl2O4 to Al2O3 is 0.034 to 62.
