Abstract:

In recent years mesoporous molecular sieves have been widely used as catalyst supports for deep hydrodesulfurization（HDS）of oil products because of their ordered pore structure，narrow pore size distribution，large surface area，high thermal and hydrothermal stability. In this paper，the advance in application of mesoporous molecular sieves MCM，SBA，HMS，KIT，etc.，in deep hydrodesulfurization of oil products is reviewed. The effects of the different modified methods of mesoporous molecular sieves，including incorporation of metals and oxides，modification of acid，addition of phosphorus，and recombination of other supports，on the structure，morphology and dispersion of the catalyst and active phase，acidity of the catalyst，interaction of active phase with support，and the HDS catalytic activity are investigated. Furthermore，the advantages and existing problems of mesoporous molecular sieves as HDS catalyst supports are discussed，and future applied prospects are forecasted.
