Title:
A manufacturing method of 1* Butene, 1, and 3* butadiene derivative
Document Type and Number:
Japanese Patent JP5911560
Kind Code:
B2
Abstract:
A process for preparing 1-butene and a 1,3-butadiene derivative, containing the steps of a) non-oxidatively catalytically dehydrogenating a feedstock gas stream containing n-butane, hydrogen, other low-boiling secondary constituents and high boilers, to form a product mixture containing unreacted n-butane, 1-butene, 2-butenes, 1,3-butadiene, hydrogen, other low-boiling secondary constituents and high boilers; b) removing hydrogen, other low boilers and high boilers, to give a product mixture containing n-butane, 1-butene, two 2-butenes and 1,3-butadiene; c) reacting some of the 1,3-butadiene obtained in the removing b), to form a derivative; d) removing the 1,3-butadiene derivative obtained in the reacting c); e) selectively hydrogenating the 1,3-butadiene not derivatized in the reacting c), to form 1-butene; and f) distillatively removing 1-butene from the hydrocarbon stream obtained in the hydrogenating e), to leave a residual stream.
