Title:
CATALYST WITH IMPROVED CONVERSION RATE AND SELECTIVITY FOR PREPARING OLEFIN AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2020/009318
Kind Code:
A1
Abstract:
The present invention provides a catalyst for preparing olefin, the catalyst having excellent conversion rate and selectivity, and a method for preparing the catalyst. The catalyst for preparing olefin, according to the present invention, comprises: a support including alumina and an auxiliary support ingredient; a main catalyst including an active metal oxide supported in the support; and a cocatalyst including an alkali metal and an oxide of a Group 6B transition metal.
