  • Preparation of an aviation fuel composition
    Patent number: 11773339
    Abstract: A method is disclosed for preparing an aviation fuel composition by subjecting a feedstock of biological and/or recycled origin to cracking in a cracking unit and to fractionation in a fractionation unit to obtain a kerosene fraction. The obtained kerosene fraction is subjected to hydrotreatment in a hydrotreatment unit to form a first jet fuel component. The formed first jet fuel component is mixed with a further jet fuel component to form a fuel composition having a wear scar diameter of 0.78 mm or less, as measured with BOCLE lubricity test method according to ASTM D5001. The feedstock contains one or more of tall oil pitch (TOP), a mixture of sludge palm oil, palm fatty acid distillate and animal fat (FATS), and used lubricant oil (ULO).

  • METHOD FOR PRODUCING RENEWABLE FUEL
    Publication number: 20230287281
    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 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.

  • Renewable base oil production engaging metathesis
    Patent number: 11643616
    Abstract: A process is disclosed for producing renewable products, such as a renewable base oil, from a feedstock of biological origin. The process includes subjecting a feedstock containing free fatty acids and fatty acid glycerides, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. An ester stream thereby obtained is then subjected to metathesis conditions in the presence of a renewable alkene to obtain a metathesis product. Separation of the metathesis product includes recovery of a fraction containing or consisting essentially of C16 fatty acid esters, which is subjected to ketonisation reaction conditions to produce long chain ketones, which after hydrotreatment meet requirements for a renewable base oil. Ketonisation reaction produces renewable alkene usable in metathesis reaction.

  • Method for producing renewable base oil and renewable fuel components
    Patent number: 11643606
    Abstract: The present disclosure relates to methods for producing renewable base oil and other valuable renewable fuel components from a feedstock of biological origin comprising free fatty acids and glycerides. The feedstock is first separated to two or more effluent streams containing a fatty acid fraction and glyceride fraction. The glycerides are hydrolyzed to free fatty acids and glycerol, and the fatty acids thus obtained are recycled to the separating. The fatty acids are then converted to the base oil by ketonisation, hydrodeoxygenation and hydroisomerisation. The glycerol is converted to propanols by selective hydrogenolysis.
