Title:
ALUMINA HAVING A COMPLEX PORE STRUCTURE, AND CATALYST AND PROCESS FOR SELECTIVE HYDROGENATION OF CRACKING GASOLINE
Document Type and Number:
WIPO Patent Application WO/2008/019581
Kind Code:
A1
Abstract:
An alumina carrier having a complex pore structure, wherein the surface area
of the carrier is in the range of 40-60m2/g, the total pore volume is
in the range of 0.3-1.2ml/g, the pore volume of the pores whose diameter is less
than 30nm takes up 5-60% of the total pore volume, the pore volume of the pores whose
diameter is between 30-60nm takes up 20-75% of the total pore volume, the pore
volume of the pores whose diameter is greater than 60nm takes up 20-60% of the total
pore volume. A catalyst for selective hydrogenation of cracking gasoline, which
comprises (a) the alumina carrier, and (b) 0.01-1.2wt% of palladium present
in the form of metal or oxide, based on the weight of the alumina carrier.
