Title:
CATALYTIC CONVERSION AND DEVICE FOR MANUFACTURING HEAVIER HYDROCARBON BY OLIGOMERIZATION OF OLEFINIC RAW MATERIAL
Document Type and Number:
Japanese Patent JPS59206485
Kind Code:
A
Abstract:
An improved continuous catalytic process is provided for oligomerizing lower olefins to heavier hydrocarbons wherein a continuous liquid olefinic feedstream is diluted with a liquid alkane stream. Such a process is improved by a technique which comprises cooling catalytically converted effluent, fractionating the effluent to obtain a condensed lower aliphatic recycle stream, a liquid C3-C4 product stream, a liquid product stream consisting essentially of C5<+> hydrocarbons and a gaseous C2<-> gaseous stream, by the sequential fractionation steps of: debutanizing the cooled effluent to obtain the liquid C5<+> hydrocarbon stream and a condensed lower aliphatic stream; de-ethanizing a portion of the lower aliphatic stream to recover gaseous offgas stream and a C3-C4 alkane product stream; and recycling at least a portion of the condensed aliphatic stream from the debutanizing step for dilution of the olefinic feedstream. An apparatus arrangement for conducting such an improved process is also disclosed.
