Abstract
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. Thy 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-Tropsch unit at H/CO ratios from 1.8 to 2.05 or treating the effluent from the Fischer-Tropsch unit with a metal oxide to remove the acids.
