Changing the properties of narrow fractions in the process of hydrotreating light coking gas oil

Currently, the main products of the delayed coking plant in the Russian Federation (after hydrotreating) are gasoline and diesel fuel summer. The paper presents the results of a study of the properties of narrow fractions of coking gas oil and hydrotreated coking gas oil, which showed the prospect of organizing production based on the coking process of more marginal aviation kerosene and winter diesel fuel. The separation of products into narrow 20 degree fractions was carried out on an automatic distillation unit AUTOMAXX 9100. The dependences of nitrogen, sulfur, aromatics, density, and low-temperature properties on the boiling temperatures of narrow fractions of the composition of light coking gas oil and hydrotreated light coking gas oil have been studied. Analysis of the properties of narrow fractions of hydrotreated light coking gas oil has shown the theoretical possibility of obtaining fractions of jet fuel and winter diesel fuel on its basis, instead of summer diesel fuel.
