    Abstract: A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. The process involves hydrotreatment of the oxygenated feedstock in a first hydrotreating reactor (101) and a further hydrotreatment in a second hydrotreating reactor (102), where between the two reactors, the gaseous phase is removed. The specific process setup effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation.

    Abstract: This invention relates to a process for preparing isooctane from an input which contains isobutene and to a combination of a hydrocarbon mixture and a fuel component. According to the process, the hydrocarbon input is brought into contact with an acid catalyst in the presence of an oxygenate under conditions in which at least a part of the isobutene is dimerized to diisobutene, and the diisobutene which has been formed is recovered and hydrogenated to give isooctane. According to the invention, the isobutene is dimerized in a reaction zone in a system which contains at least one reaction zone and one distillation zone. The effluent from the reaction zone is conveyed to the distillation zone, where diisobutene is separated from the effluent, and a flow, which contains oxygenate or reaction product and which is circulated back to dimerization, is withdrawn from the distillation zone. The process according to the invention is used to achieve a more dimer-selective process, with a lower input of alcohol than in the prior art.
