摘要： A process is disclosed for the preferential conversion to 2-butene of a stream containing C4 compounds including 1-butene and 2-butene. The process involves 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. A corresponding apparatus also is disclosed.

摘要： The C3 to C6 cut from a cracking process containing propylene, butane, 1-butene, 2-butene and acetylenic and diene components including butadiene are preferentially converted to propylene. The cut is simultaneously fractionated and catalytically hydrogenated to hydrogenate the acetylenic and diene components. The fractionation and subsequent separation recovers a C4 component comprising a mixture of isobutene, 1-butene and 2-butene. This C4 component is then further simultaneously fractionated and catalytically hydrogenated and hydroisomerized to hydrogenate remaining butadiene, remove isobutene overhead and convert 1-butene to 2-butene leaving a bottoms of 2-butene. The 2-butene is then injected with ethylene and catalytically metathesized to form propylene.

摘要： A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle.
