A method of making a hydrodesulfurization catalyst having nickel and molybdenum sulfides deposited on a support material containing mesoporous silica that is optionally modified with zirconium. The method of making the hydrodesulfurization catalyst involves a single-step calcination and reduction procedure. The utilization of the hydrodesulfurization catalyst in treating a hydrocarbon feedstock containing sulfur compounds (e.g. dibenzothiophene, 4,6-dimethyldibenzothiophene) to produce a desulfurized hydrocarbon stream is also provided.

Claimed herein is a method of applying amorphous Co—SiOx to activate PMS and produce SO.sub.4..sup.− due to the formation of Co(II)-O.sub.v, pairs via the substitution of Si by Co. The inherent Co significantly change the electronic structure of O and Si atoms in the Co—SiOx via final state effects and increase the conductivity in terms of more effective electron transfers. The claimed method using Co—SiOx functions as a more effective oxidative catalyst for the faster degradation of pollutants. The simplicity of the synthetic procedures indicates that the conductive Co—SiOx could be used for the activation of PMS and other electrochemical applications on a wider scale.

A layered catalyst reactor system and process for hydrotreatment of hydrocarbon feedstocks. The layered catalyst system reactors comprise vertical bed layers including a demetallization catalyst layer, multiple layers of supported hydrotreating catalyst layer, and multiple alternating layers of supported hydrocracking catalysts and self-supported hydrotreating catalysts. The arrangement of the catalyst layers mitigates the risk of temperature run-aways, with improvements in hydrotreatment performance.
