METHOD OF PURIFYING OIL PRODUCTS AND SORBENTS FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC C10G29/00 C10G25/05 C10G27/12 

FIELD: chemistry.

SUBSTANCE: method of purifying light oil products is carried out by passing the prepared sorbent through a layer, the purification of light oil products is carried out in the liquid-vapour phase with the use of a sorbent-based zeolite of the structure ZSM-5 modified by peroxosolvate or sodium peroxocarbonate within the temperature range of T=50-100°C at a pressure of P=1-2 atm with a volumetric rate not higher than 100 h^-1, and the mixture of the components for the preparation of a sorbent has the following chemical composition: high siliceous zeolite of the structure ZSM-5 and sodium peroksoborat (Na₂SiO₄) in the ratio of 1÷1; high siliceous zeolite of the structure ZSM-5 and sodium peroxocarbonate (Na₂C₂O₆) in the ratio of 2÷1. The object of the present invention is to provide sorbents that promote a high degree of purification of light oil products.

EFFECT: simplification and continuity of the technological process.
