STUDY OF DEHYDROGENATION OF LIQUEFIED PETROLEUM GASES USING METAL-CONTAINING CATALYSTS

In recent years, the constant rise in energy prices, limited global oil reserves and the deteriorating environmental situation around the world have made the active use of so-called renewable natural and energy resources urgent. This should be facilitated, in particular, by the following measures to reorient the raw material base for the production of petrochemical products from oil to oil and gas raw materials.

This review presents an analysis of known catalysts developed industrially for the dehydrogenation of light alkanes. Catalysts based on platinum, aluminochrome, iron oxide, molybdenum oxide and vanadium oxide were considered. For each of them, the corresponding properties, component composition, raw materials, areas of application, advantages and disadvantages are given. Various developments in the use of metal or metal oxide promoters to improve the conversion and selectivity of the dehydrogenation process were discussed.

The purpose of this scientific work was to study the physicochemical properties of supported metal oxide, monometallic and bimetallic catalysts in the propane dehydrogenation reaction, and to study the influence of reaction conditions on the yield of propylene.

Under industrial conditions, the achievable propane conversion ranges from 25 to 65%, and the propylene selectivity does not exceed 90%. The main idea is that these data provide the basis for the development of a new generation of dehydrogenation catalysts. The use of these catalysts would significantly improve the main parameters of the process, as well as solve the problem of reducing coke formation.
