Abstract
The urgency of creating new efficient catalysts for the processes of deepening oil refining rises on the background of stricter requirements for the quality of motor fuels, as well as the deterioration of the quality of crude oil for processing, and an increase in the number of distillates of secondary processes involved in the production of commodity petroleum products. In this work, alumina-catalytic systems were synthesized using polyoxomolybdate compounds. The morphology, structure and phase composition of the synthesized catalytic systems were studied using the following analysis methods: scanning electron microscopy, microelement analysis, X-ray phase analysis, X-ray diffraction, electron spectroscopy. It has been established that the Mo / AI2O3 system is active in the process of thermal catalytic conversion of heavy residual raw materials.
Highlights
The world oil refining is currently characterized by a reduction in light and medium oil reserves, an increase in the share of extraction and processing of heavy oil and sour crude oil, environmental protection requirements for oil products quality are becoming tougher [1,2,3,4,5]
Increasing demand for motor fuels of improved quality is applied by the development and implementation of technologies aimed at the deep processing of oil residues and the maximum removal of sulfur-containing compounds
The morphology of both samples is a particle of spheroid shape
Summary
The world oil refining is currently characterized by a reduction in light and medium oil reserves, an increase in the share of extraction and processing of heavy oil and sour crude oil (total sulfur content is about 0.6-3.5% by mass), environmental protection requirements for oil products quality are becoming tougher [1,2,3,4,5]. These factors necessitate the restructuring and modernization of the oil refining industry, the construction of new facilities with an increase in refining depth and a reduction in fuel oil consumption, as well as the intensification of the production of high-quality motor fuels.
