Selective Hydrogenation Catalyst of Ni-Mg/Al 2 O 3 for FCC Light Gasoline.

A catalyst is provided for the selective hydrogenation of dienes from fluid catalytic cracking gasoline. There are a small quantity of dienes in fluid catalytic cracking gasoline which can deteriorate the quality of fluid catalytic cracking gasoline, as well as make its further process inconvenient. These dienes must be reduced as impurity. In this paper, the nickel supported on alumina selective hydrogenation catalysts modified with magnesium promoter are prepared by impregnation method. The fluid catalytic cracking gasoline ( -1 , the volume ratio of hydrogenation and oil ( V H / V O ) is 10, and the reaction pressure is 1.5 MPa. The temperature of calcination is observed as well, and the optimal one is 1, 000°C [ABSTRACT FROM AUTHOR]
