Synthesis of Ni-Mo binary transition metal complex and application in hydrodesulfurization

The study showed the synthesis of nickel-molybdenum binary metal complex ni(en)3moo4 with high purity from the impregnating solution. the complex was characterized and confirmed by single-crystal xrd,ft-ir and tga. the binary transition metal complex was impregnated to γ-al2o3 to prepare hydrodesulfurization catalyst. the catalyst was characterized by low temperature n2 adsorption-desorption isotherms,xrd and hrtem. no molybdenum and nickel species were observed over the hydrodesulfurization catalyst surface,and the average slab length and layer number of the mos2 crystallites in the catalyst are 2.6 nm and 2.3,respectively. the results indicated the high dispersion of active metal species over support. the dbt conversion of the catalyst can reach 91.4%,and the overall pseudo-first order rate constant kdbt is 3.1×10-4 gcat -1 s-1. the result showed the catalyst possessed good catalytic activity and ni(en)3moo4 can make efficient precursor to produce hydrotreating catalyst. © 2017 chemical society of pakistan. all rights reserved.
