Abstract:
In a market economy, gasoline hydrotreating at modern oil refineries is considered one of the most important technological processes. In conditions where the demand for high-quality gasoline on the world market is high, control of the gasoline hydrotreating process is a very pressing issue. As oil refineries strive to meet stricter environmental regulations, hydrotreating processes are becoming increasingly important. An automated control system has been developed for such a technological process. During hydrotreating, petroleum fractions selectively react with hydrogen in the catalyst presenc

Currently, one of the main important tasks at oil refineries is to increase their productivity and product quality. Hydrotreating of diesel fuel is important in the oil refining process. The main purpose of hydrotreating is to improve the quality of fuel and remove sulfur, nitrogen and oxygen compounds from it. The diesel fuel hydrotreating process has a significant impact on product quality. As an object of study, a chemical reactor has a nonlinear characteristic and has the property of a reverse chemical reaction during the hydrotreating of diesel fuel.

Hydrogenation processes of oil residue refining are widely studied by Russian and foreign scientific groups, but so far they have practically not been implemented at domestic refineries. Due to the increased requirements for the quality of petroleum products, including fuel oil, as well as an increase in the proportion of heavy fractions, there is an urgent issue of upgrading and increasing secondary processes for refining residual raw materials and increasing the proportion of light fractions.

A novel near-zero-emission process for obtaining clean middle-distillate fuels, primarily from coal and with some algal input, has been developed. This process involves the solvent extraction of coal, followed by two stages of hydrotreating and hydrogenation, and finally distillation, to produce fuels of very low sulfur and low aromatics content. Prototype fuels have been shown to provide performance comparable to petroleum-derived jet and diesel fuels in gas turbine and small diesel engines, as well as in the solid oxide fuel cell.
