Abstract

The process of thermoadsorption upgrading of the heavy oil residue - tar from the Pavlodar petrochemical plant with the purpose of reducing the content of metals and sulfur was carried out. Adsorbents based on zeolite modifi ed with nanosized vanadium and carbon additives have been tested for the process. Optimum parameters of the process were established: temperature 350-360 °C, duration 4 h. As a result of the demetallization and desulfurization process, the degree of vanadium and nickel recovery was 84-88%, and the sulfur content decreased from 2.9 to 1.9%.
