PROCESS FOR REMOVING POLYUNSATURATED HYDROCARBONS FROM C4 HYDROCARBON STREAMS IN THE PRESENCE OF MERCAPTANS, DISULFIDES AND C5 HYDROCARBONS

摘要

The present invention provides a two-stage process for removing polyunsaturated hydrocarbons from C4 hydrocarbon streams that, in addition to C4 hydrocarbons, also contain C5 hydrocarbons and mercaptans and/or disulfides.
