HYDROCARBON FEEDSTOCK HYDROPYROLYSIS PROCESS Russian patent published in 2005 - IPC

Abstract RU 2249611 C1

FIELD: petrochemical processes.

SUBSTANCE: hydropyrolysis of hydrocarbon feedstock is effected in tubular pyrolysis furnace in presence of steam and hydrogen. Hydrocarbon feedstock is, in particular, a mixture of gasoline and hydrogenated C₉₊-fraction of liquid pyrolysis products isolated as side-cut distillate from bottom residue obtained in fractionation of C₆-C₁₀₊-fraction of liquid pyrolysis products to produce benzene-toluene fraction, the two mixture components being taken at weight ratio (70-80):(20-30), respectively. Molar ratios hydrogen/hydrocarbon feed and hydrogen/C₉₊-fraction are (1-3):1 and (5.3-15.85):1, respectively.

EFFECT: increased yield of benzene-toluene fraction and benzene content in aromatic fraction of liquid pyrolysis products.
