A process for the preparation of detergents involving separating the hydrocarbonaceous product stream from a Fischer-Tropsch process producing normally liquid and normally solid hydrocarbons into a light fraction and one or more heavy fractions, hydrogenating at least part of the light fraction to convert unsaturated hydrocarbons and/or oxygenates into saturated hydrocarbons, distilling product thus obtained into at least one fraction comprising detergent hydrocarbons, dehydrogenating at least part of the detergent hydrocarbons to obtain a detergent hydrocarbon stream having mono-olefins and converting the mono-olefins into detergents. The invention further concerns a process for the preparation of detergents in which process a hydrogenated product, which is obtained according to the above process, is dehydrogenated to obtain a detergent hydrocarbon stream of mono-olefins, followed by conversion of the mono-olefins into detergents. Further, the invention relates to the combined production of detergents or detergent hydrocarbons and fuels from Fischer-Tropsch hydrocarbonaceous reaction product.

(canceled)
A process for the preparation of detergent hydrocarbons comprising separating a hydrocarbonaceous product stream of a Fischer-Tropsch process producing normally liquid and normally solid hydrocarbons into a light fraction comprising mainly C18-hydrocarbons, and one or more heavy fractions comprising the remaining hydrocarbons, hydrogenating the light fraction to convert unsaturated hydrocarbons and/or oxygenates into saturated hydrocarbons, distilling product thus obtained into at least one fraction comprising detergent hydrocarbons and optionally one or more reject streams and optionally dehydrogenating at least part of the detergent hydrocarbons to obtain a detergent hydrocarbon stream comprising mono-olefins.
A process for the preparation of detergents comprising dehydrogenating detergent hydrocarbons to obtain a detergent hydrocarbon stream comprising mono-olefins and converting the mono-olefins into detergents, wherein the detergent hydrocarbons are prepared by a process comprising separating the product stream of a Fischer-Tropsch process into a light fraction comprising mainly C18-hydrocarbons, and a heavy fraction comprising the remaining hydrocarbons, hydrogenating the light fraction to convert unsaturated hydrocarbons and/or oxygenates into saturated hydrocarbons, and, distilling product thus obtained into at least one fraction comprising detergent hydrocarbons.
