DOUBLE BOND HYDROISOMERIZATION OF BUTENES

A PROCESS IS DISCLOSED FOR THE PREFERENTIAL CONVERSION TO 2-BUTENE OF A C4 STREAM CONTAINING 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...

Summary:A PROCESS IS DISCLOSED FOR THE PREFERENTIAL CONVERSION TO 2-BUTENE OF A C4 STREAM CONTAINING 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 -BUTANE TO 2-BUTENE, THEREBY PRODUCING A HYDROISOMERIZATION EFFLUENT, SEPARATING THE HYDROISOMERIZATION EFFLUENT IN A FRACTIONATION COLUMN HAVING AN UPPER END AND A LOWER END TO FORM A 1-BUTENE MIXTURE AT THE UPPER END, A TOP EFFLUENT STREAM CONTAINING ISOBUTENE AND ISOBUTYLENE AND A BOTTOMS STREAM CONTAINING 2-BUTENE, AND HYDROISOMERIZING THE 1- BUTENE MIXTURE AT THE UPPER END OF THE COLUMN USING A SECOND HYDROISOMERIZATION CATALYST. A CORRESPONDING APPARATUS ALSO IS DISCLOSED.
