CATALYST OF SELECTIVE HYDROGENATION AND METHODS OF ITS PRODUCTION AND APPLICATION Russian patent published in 2018 - IPC B01J21/04 B01J23/44 B01J23/50 B01J37/02 B01J37/06 B01J37/08 B01J37/24 B01J35/10 C07C5/08 C07C7/167 

FIELD: chemistry.

SUBSTANCE: composition is described, comprising an extruded inorganic support containing a metal or metalloid oxide, and, at least, one catalytically active metal of group 10. The extruded inorganic substrate has pores, a total pore volume and a pore size distribution. The pore size distribution profile has, at least, two peaks of pore diameters, each peak having a maximum. The first peak has the first maximum of pore diameters of more than 1000 nm to 6000 nm, and the second peak has the second maximum of pore diameters of less than about 120 nm; and about 15% or more of the total pore volume of the extruded inorganic substrate are within the range of the first peak of the pore diameters. The composition has a total pore volume of 0.1-0.6 cm³/g.

EFFECT: good activity and increased selectivity of the catalyst.
