IMPROVED PROCESS FOR MAKING FISCHER-TROPSCH OLEFINIC NAPHTHA AND HYDROGENATED DISTILLATES

摘要

A process is described by which an olefinic naphtha and a hydrogenated distillate fuel are made from a Fischer-Tropsch process. The olefinic naphtha is suitable for use in an ethylene cracker where the olefins enhance the formation of ethylene. The hydrogenated distillate fuel is used in jet and or diesel fuels. Optionally the olefinic naphtha has a low content of acids. This low acid content is obtained by operating the Fischer-Trospch unit at H<SUB>2</SUB>/CO ratios from 1.8 to 2.05 or treating the effluent from the Fischer-Trospch unit with a metal oxide to remove the acids.
