como hydrodesulphurization catalyst supported over a binary zeolite (hzsm-5)-kit-6 siliceous nanomaterial

The elimination of sulfur compounds is important in producing green fuels according to environmental regulations. in this regard, a novel nanocatalyst has been prepared for hydrodesulphurization of dibenzothiophene.crystalline binary hzsm-5/kit-6 material was successfully synthesized. hzsm-5/kit-6 material has a hierarchically porous structure and a large nanoporous surface area. following impregnation with co and mo species, the obtained catalyst (como@hzsm-5/kit-6) shows high activity in the hydrodesulphurization of dibenzothiophene.the catalytic activity of the como@hzsm-5/kit-6 catalyst was evaluated at 400 ºc and atmospheric pressure. for this catalyst, the conversion of total sulfur was obtained as 98.18%.
