INTEGRATED PROCESSES FOR PRODUCING BUTENE-1

摘要

Integrated process for the production of butene-1 which comprises feeding a C4 hydrocarbon stream to a separation unit of butene-1 and recycling the remaining stream to the same unit after treatment in a bond isomerization section to convert the remaining butenes-2 into butene-1, a molecular sieve separation unit is inserted in the cycle operating with the hydrocarbons in a vapour phase, for the purge of the paraffins.
