The present invention provides a process to prepare middle distillates and base oils from a Fischer-Tropsch product, by (a) subjecting the Fischer-Tropsch product to a hydroprocessing step in the presence of a catalyst comprising a molecular sieve with a pore size between 5 and 7 angstrom and a SiO/AlOratio of at least 25, preferably from 50 to 180 and a group VIII metal to obtain a mixture comprising one or more middle distillate fractions and a first residual fraction and a naphtha fraction; (b) separating the mixture as obtained in step (a) by means of atmospheric distillation into one or more middle distillate fractions, a first residual fraction and a naphtha fraction; (c) separating the first residual fraction by means of vacuum distillation into at least a distillate base oil fraction and a second residual fraction.

Process to prepare Fischer-Tropsch derived middle distillates and base oils

A liquid fuel composition for a spark ignition internal combustion engine comprising (a) gasoline blending components, (b) Fischer-Tropsch derived naphtha at a level of up to 50% v/v and (c) oxygenated hydrocarbon at a level less than 50% v/v. While the low octane number of Fischer-Tropsch derived naphtha would normally severely restrict its blendability in gasoline to low levels, it has now been found that Fischer-Tropsch derived naphtha can be included in, for example, ethanol-containing gasoline fuel compositions, in surprisingly and significantly high blend ratios of Fischer-Tropsch derived naphtha to ethanol.

Fuel composition

A catalyst system for dewaxing of a hydrocarbon feedstock comprising a mixture of a first dewaxing catalyst composition and a second dewaxing catalyst composition, wherein the first dewaxing catalyst composition is a ZSM-12 zeolite based catalyst composition and the second dewaxing catalyst composition is a EU-2 and/or ZSM-48 zeolite based catalyst composition, and wherein a concentration gradient of the mixture is achieved within a single catalyst bed, such that the concentration of the first dewaxing catalyst is decreasing and the concentration of the second dewaxing catalyst is increasing through the catalyst bed; and a process for dewaxing of a hydrocarbon feedstock comprising contacting the hydrocarbon feedstock with said catalyst system.

Catalyst system for dewaxing

A catalyst system for dewaxing of a hydrocarbon feedstock comprising at least two catalytic sections, the first section comprising a first dewaxing catalyst and a subsequent section comprising a second dewaxing catalyst, wherein the first dewaxing catalyst is a ZSM-12 zeolite based catalyst and the second dewaxing catalyst is a EU-2 and/or ZSM-48 zeolite based catalyst. The catalyst system displays enhanced performance when compared to systems containing either ony ZSM-12 based catalyst or EU-2/ZSM-48 based catalyst only.
