Apart from more severe process conditions or major investments into plants, ever more active hydrotreating catalysts should be developed to meet the growing demand for cleaner fuels. Transition metal sulfides have been widely used as hydrotreating catalysts that are small crystallites of Mo sulfide promoted with Co or Ni supported on alumina. We have reported optimization of NiMo HDS catalysts prepared on Nb modified silica mesoporous supports by treating with thioglycolic acid (TGA) [1]. It was found that simultaneous impregnation by Ni, Mo and thioglycolic acid led to higher HDS activities than the sequential treatment of the calcined NiMo catalysts by TGA. This observation is due to formation of a complex of the Mo and/or Ni atoms with TGA.
