Studies of the process of processing natural and associated petroleum gases into high-quality synthetic oils have been carried out, technological parameters have been determined that make it possible to obtain synthesis products with a high content of hydrocarbons from engineering. The influence of the type of zeolite on the composition of the resulting products in single-reactor synthesis is investigated. The influence of temperature (240-250 °C) and pressure (1.0-2.0 MPa), as well as the hydrogenating additive Pt on the one-stage process of obtaining hydrocarbons for fuel and lubricating purposes was determined. A composite bifunctional zeolite-containing catalyst for the synthesis of fuel and lubricating hydrocarbons with a high content of branched hydrocarbons in the synthesis products has been developed. The performance of the catalyst for hydrocarbons C5+ - 146.4 kg/ (m3/ h) has been achieved.

Studies of a multifunctional catalyst for the stability of operation at a pilot catalytic plant by the flow method in a tubular reactor with a steam-water cooling circuit have been performed. The properties of laboratory samples of motor oil obtained on a multifunctional catalyst have been studied. It was found that the samples of motor oils are dark yellow transparent liquids with a characteristic odor and viscosity. A set of measures is proposed to refine the properties of laboratory samples of oils for use in internal combustion engines. The technological regulations and the scheme of production of a multifunctional catalyst have been developed. The production of the catalyst is carried out in a periodic way, consisting in mixing fine powders of the catalyst for the synthesis of hydrocarbons with zeolite with a binder and subsequent heat treatment of the catalyst granules in a certain mode. The technology of processing natural and associated petroleum gases into high-quality synthetic oils for use in internal combustion engines has been developed. The technological scheme of a modular unit for processing natural and associated petroleum gases into high-quality synthetic oils is proposed, the material balance of the main stages of the process is calculated.
