AN APPARATUS FOR COPRODUCTION OF ISO TYPE ALDEHYDES AND ALCOHOLS FROM OLEFINS, AND A METHOD FOR COPRODUCTION USING THE APPARATUS

摘要

PURPOSE: An apparatus for coproduction of iso type aldehydes and alcohols from olefins is provided to improve the efficiency of manufacturing aldehydes by increasing the contacting surface of liquid olefin and mixed gas. CONSTITUTION: An apparatus for coproduction of iso type aldehydes and alcohols from olefins comprises a hydrogenation reactor, a first main distillation column, a hydrogenation reactor, a pore (fore) distillation column, a second main distillation column, a post distillation column, and pipes. Among the first main distillation column and the second main distillation column, only one column operates. The hydrogenation reactor is a loop type reactor or a double fixed layer type reactor including a spraying component, a highly activated nickel catalyst layer, a lowly activated copper catalyst layer, and a loop type reactor or a double fixed layer type reactor including the exit of a hydrogenation reactor.
