METHOD OF REMOVING TAR-FORMING COMPONENTS FROM PYROLYSIS GASOLINES

摘要

FIELD: petroleum processing. SUBSTANCE: invention relates to purification of hydrocarbon raw destructive processing products, in particular, unstable pyrolysis gasolines. The latter in gas phase are brought into contact with zeolite-containing alumino-silicate catalyst in reaction apparatus for further separation of formed oligomers from vapors in separation zone of the same apparatus at the same temperature at which gasoline vapors leave fractionation column. EFFECT: simplified process. 2 dwg
