TH50082A3 - Process for the refining of reactive paraffinic hydrocarbons Fischer-Tropsch - Google Patents

Abstract

DC60 (31/05/44) The process for distillation of paraffinic hydrocarbons consists of Material feeding Entered into paraffinic hydrocarbons obtained from the reaction. Fischer-Tropsch Which contains paraffin nick Light and / or moderate hydrocarbons into the distillation column. A distillation column has been carried out for production. Usable wax products The overhead currents, bottom currents and at least one side currents were removed from the distillation column, all of the resulting waxy products were waxy products.
