A PROCESS FOR THE PREPARATION OF DETERGENT COMPOUNDS

摘要

THE INVENTION CONCERNS A PROCESS FOR THE PREPARATION OF DETERGENTS CONTAINING A RELATIVELY LOW AMOUNT OF ISOPARAFFINS, COMPRISING SEPARATING A HYDROCARBONACEOUS PRODUCT STREAM FROM A FISCHER-TROPSCH PROCESS USING A COBALT BASED CATALYST AND PRODUCING NORMALLY LIQUID AND NORMALLY SOLID HYDROCARBONS INTO A LIGHT FRACTION BOILING BELOW AN INTERMEDIATE FRACTION COMPRISING DETERGENT HYDROCARBONS, AN INTERMEDIATE BOILING FRACTION COMPRISING DETERGENT HYDROCARBONS , FOLLOWED BY CONVERSION OF THE DETERGENT HYDROCARBONS PRESENT IN THE INTERMEDIATE BOILING FRACTION INTO DETERGENTS, THE FISCHER-TROPSCH PROCESS BEING CARRIED OUT AT A RELATIVELY HIGH PRESSURE.
