Title:
ブテンの二重結合ヒドロ異性化法
Document Type and Number:
Japanese Patent JP5385606
Kind Code:
B2
Abstract:
An apparatus is described for the preferential conversion to 2-butene of a stream containing C4 compounds including 1-butene and 2-butene involving mixing the C4 stream with a first hydrogen stream to form a feed stream, hydroisomerizing the feed stream in the presence of a first hydroisomerization catalyst in order to convert at least a portion of the 1-butene to 2-butene, thereby producing a hydroisomerization effluent, passing the hydroisomerization effluent through a fractionation column to form a top stream comprising isobutane and isobutylene and a bottoms stream comprising 2-butene, withdrawing a recycle stream from said fractionation column at a location above the feed point at which the weight ratio of 1-butene to 2-butene is high, and combining the recycle stream with at least one of the C4 stream and the feed stream upstream from the hydroisomerization catalyst.
