Title:
ALUMINA SUPPORT
Document Type and Number:
WIPO Patent Application WO/2022/030515
Kind Code:
A1
Abstract:
Provided are: an alumina support which is used in a catalyst for gas phase reactions, makes catalytic reactions highly active, and reduces the yield of by-products; and a gas phase reaction catalyst having a metal compound supported on the alumina support. The alumina support used in a catalyst for gas phase reactions has a cylindrical form having at least one hollow through hole, and has a BET specific surface area of 140-280 m2/g, a pore volume (total pore volume) of 0.04-0.15 cm3/g for pores having a pore diameter of 15-20000 nm and a pore volume of 0.02 cm3/g or less for pores having a pore diameter of 1000-20000 nm, as measured by the mercury intrusion method, and a tapping bulk density of 620-780 g/L.
