Characteristics of Distillation Residues from Liquid Pyrolysis Products

详细

Heavy ends obtained from thermomechanical distillation of water-tar emulsions of liquid pyrolysis products from a broad fraction of light hydrocarbons and the ethane fraction were studied. Their physicochemical parameters were determined. Various processing schemes for heavy ends were proposed. It was found that the properties of used diesel fuel (UDF) were closest to those of the products. The high densities of the products limited the use of heavy ends as UDF. This problem was solved by proposing a shift of the UDF and vat residue ratio to 4:1 to produce commercial UDF blends.
