Tailoring NiMo-Based Catalysts for Production of Low-Viscosity Sustainable Hydrocarbon Bases for Drilling Muds from Secondary Gas Oils

This article presents the prospect of using process deep hydrodesulfurization and hydrodearomatization secondary gas oils highly active NiMo catalysts to obtain hydrocarbon bases for drilling fluids. Catalysts were synthesized PMo heteropolyanions, citric acid, diethylene glycol on alumina carriers with different pore volumes. study showed that concentration impregnating solution affects composition morphology phase particles prepared catalyst, while textural characteristics carrier influence physicochemical properties catalytic activity NiMo/Al2O3 catalysts. The catalyst was a largest volume an effective diameter more than 7 nm exhibited highest activity. It demonstrated use such allows procurement fluids from mixtures at hydrogen pressure 15–20 MPa. has practical significance development sustainable economically efficient methods utilization low-quality petroleum produce high-margin environmentally friendly non-fuel products, as well contributes technologies raw materials.
