Description
Summary:The expanding use of low-quality crude oil materials in refinery demands the creation of new-generation catalysts for the comprehensive hydrorefinery of hydrocarbon fraction. A technology was developed for the preparation of catalysts based on mesoporous titanium silicate Ti 0.03 Si 0.97 O 2 with NiO nanocrystals (4.1–4.7 nm) incorporated in pores. Two methods were suggested for preparation of composite catalytic systems: first, the NiO phase was formed directly in pores of titanium silicate from microemulsion; second, NiO crystallites were prepared by cryoprocessing of initial colloid and incorporated as microsuspension in Ti 0.03 Si 0.97 O 2 pores. In the latter case, the formation of new bonds was found between silicate and NiO, evidencing the formation of a material with new physicochemical properties. The reported results can be applied to the development of mesoporous catalysts for the hydrorefinery of oil fraction.
