STUDY OF TOLUENE-CONTAINING RESIDUE FROM RECTIFICATION PROCESSING IN COKE PRODUCTION
The paper is devoted to research on processing of residue from rectification formed in the process of obtaining high-quality benzene from a mixture of benzene hydrocarbons captured from gaseous coking products. At the stage of rectification of crude coal benzene is formed residue containing high boiling relative to benzene aromatic hydrocarbons - toluene, xylene and others. The paper considers the possibility of rectification separation of this mixture to obtain marketable products.
