Abstract: Here is provided processes for producing at least one liquid transportation fuel component. In a first mode of running one of the processes, a hydrocarbon feed comprising nitrogen impurities is subjected to a hydroprocessing in reactor A in the presence of a hydrotreatment catalyst A to obtain a hydroprocessing effluent A, which is subjected, after degassing, to a catalytic hydroprocessing in reactor B to obtain a hydroteratment effluent B, which is fractionated, optionally after degassing, to obtain at least one liquid transportation fuel component, preferably at least an aviation fuel component. In the process, parameters indicative of deactivation of the hydrotreatment catalyst A are monitored and when these reach predetermined values, the process is switched to a second mode of running wherein the order of reactors A and B is changed so that a degassed hydroprocessing effluent B is fed to the reactor A.

Abstract: A process for producing at least one liquid transportation fuel component is provided. In the process, a paraffinic hydrocarbon feed is provided and subjected to hydroisomerisation to obtain a hydroisomerisation effluent; from which hydroisomerisation effluent a recycle stream is separated and subjected to hydrocracking to obtain a recycle effluent, the hydroisomerisation effluent and the recycle effluent being fed to fractionation, from which fractionation at least one liquid transportation fuel component is recovered.

Abstract: A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity. The process involves hydrotreatment of feedstock (104) in a first hydrotreating bed (105) arranged downstream of a polishing bed (102). After the first hydrotreating bed, the gaseous phase is removed and the liquid hydrotreated phase is fed to the polishing bed (102) arranged upstream of the first hydrotreating bed together with fresh hydrogen (120), which further reduces any nitrogen impurities in the polished hydrocarbon product. Nitrogen impurities are removed from this hydrocarbon product causing an improved cloud point after isomerisation. The specific arrangement makes efficient use of fresh hydrogen for polishing, providing a polished hydrocarbon product rich in dissolved hydrogen, where part of such product can be used as hydrocarbon diluent in the downstream hydrotreating bed, and/or withdrawn between the polishing and hydrotreating bed and isomerised in an isomerisation reactor.

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.
