Hydrodesulfurization of thiophene over bimetallic ni–mo sulfide catalysts prepared by different methods catalysts prepared by different methods

الملخص EN

-Bimetallic Ni–Mo sulfide Al2O3 catalysts were prepared by impregnation (IMPR), mechanical (MECH) and organic matrix combustion (OMXC) methods.

The prepared catalysts were characterized by nitrogen physisorption, X-ray diffraction, electron probe microanalysis, and Raman Spectroscopy.

The samples were sulfided and their activity in hydrodesulfurization (HDS) of thiophenes at a pressure of 1 atm and a temperature of 350ºC was tested.

It was found with Ni–Mo that the catalyst prepared by the OMXC method is more active (by upto 57%) as compared with the corresponding catalysts prepared by (MECH) and conventional impregnation methods.
