Abstract. The article examines the work of domestic technology for the selective purification of diesel fractions from n-paraffins by adsorption on zeolites in order to assess the maximum possible level of depression of the mixed fraction of heavy atmospheric gas oil and light vacuum gas oil (fraction 240-410^оС) during the industrial implementation of this technology at Slavyansk ECO LLC. The article reviews the actual data on the operation of the selective purification unit and provides an assessment of the process performance indicators achieved during the processing of the 240-410°C fraction. The efficiency of the selective purification process of the mixed fraction of heavy atmospheric gas oil and light vacuum gas oil from n-paraffins by adsorption on zeolites is considered.
