Al-modified mesocellular silica foam as a superior catalyst support for dibenzothiophene hydrodesulfurization

Al-containing mesostructured cellular silica foams (Al-MCFs) with different Si/Al ratios were used as supports for HDS catalysts. NiMo/Al-MCFs(20) had suitable acidity properties, good dispersions of Ni and Mo active phases, and the highest catalytic activity for HDS of DBT.
