A method for treating a lipid material containing phosphorous and/or metal compounds is described. The method includes providing the lipid material, preheating the lipid material, to obtain a preheated lipid material, heat treating the preheated lipid material in a heat treatment step, to obtain a heat treated lipid material, and optionally post treating the heat treated lipid material in a post treatment step.

Method for treating lipid materials

The present invention relates to a method for reducing deactivation of a hydrotreatment catalyst. The hydrotreatment catalyst is used as a main active catalyst for producing renewable hydrocarbons by hydrotreatment from a renewable feedstock which comprises at least an oxygen containing compound, at least one metal containing compound and at least one phosphorus containing compound as impurities. The method comprising adjusting the metal to phosphorus (M:P) weight ratio of the renewable feedstock to a value within the range from 0.70 to 1.26, measured as elemental metal and elemental phosphorus, subjecting the obtained feedstock to a temperature of from 190 to 400° C. under reducing conditions, thereby forming a solid precipitate comprising at least one metal and phosphorus containing compound, and contacting the obtained liquid renewable feedstock with the main active catalyst, in the presence of hydrogen.

A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. Hydrotreatment of the oxygenated feedstock occurs in a first hydrotreating bed arranged downstream of a polishing bed. A gaseous phase is removed and the liquid hydrotreated phase is fed to the polishing bed arranged upstream of the first hydrotreating bed together with fresh hydrogen. The process effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation, and the arrangement makes efficient use of fresh hydrogen for polishing, providing a polished hydrocarbon product rich in dissolved hydrogen. Part of the product can be used as hydrocarbon diluent in the downstream hydrotreating bed, and/or withdrawn between the polishing and hydrotreating bed and isomerised in an isomerisation reactor.

Method for producing renewable fuel

Present disclosure relates to a novel process for purification of lipid material for further use as such as, for example, a source of fuel of chemicals.

Apparatus and method for heat treating a feedstock comprising a lipid material

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 and a further hydrotreatment in a second hydrotreating reactor, 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.

The use of bio oil from at least one renewable source in a hydrotreatment process, in which process hydrocarbons are formed from said glyceride oil in a catalytic reaction, and the iron content of said bio oil is less than 1 w-ppm calculated as elemental iron. A bio oil intermediate including bio oil from at least one renewable source and the iron content of said bio oil is less than 1 w-ppm calculated as elemental iron.

Water treatment of lipid material

The present invention relates to hydrocarbons and particularly to the manufacture of hydrocarbon components suitable as aviation fuels or jet fuels and as blending stocks for aviation fuels. The process comprises the stages, wherein in the first stage an oil feed of biological origin and hydrogen gas are subjected to conditions sufficient to effect hydrodeoxygenation in the presence of a hydrodeoxygenation catalyst to yield n-paraffins; in the second stage the n-paraffins and hydrogen gas are subjected to conditions sufficient to effect isomerization in the presence of an isomerization catalyst to yield isoparaffins and separating fractions; and recycling the fraction boiling at a temperature above 200&#xb0; C. under atmospheric pressure obtained from the second stage to reisomerization, where isomerization is effected in the presence of an isomerization catalyst.
