Disordered mesoporous KIT-1 and a support for hydrodesulfurization catalysts

摘要

MoO_3 and NiO were supported on KIT-1, a new disordered mesoporous molecular sieve, MoO_3 is homogeneously dispersed as a monolayer on the support, whereas NiO tends to form NiO tends to form small crystallites in the mesoporous channels. KIT-1 supported MoO_3 and / or NiO catalysts exhibit higher catalytic activities for thiophene hydrodesulfurization than similar MCM-41 and NaY zeolite supported catalysts, because the three-dimensional disordered network of short channels in KIT-1 reduces the risk of blockage in the catalysts and facilitates the transport of reactant and product molecules.
