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).

Abstract: The invention is directed to a fuel composition for diesel engines. The fuel composition comprises 0.1-99% by weight of a component or a mixture of components produced from biological raw material originating from plants and/or animals and/or fish. The fuel composition comprises 0-20% of components containing oxygen. Both components are mixed with diesel components based on crude oil and/or fractions from Fischer-Tropsch process.

Abstract: A method is disclosed for preparing a renewable fuel blend. The method includes subjecting at least two feedstocks of different biological origins to catalytic cracking in a catalytic cracking unit and to hydrotreatment in a hydrotreatment unit to form a fuel blend having an aromatic hydrocarbon content from 26 to 42 wt-% and a paraffinic hydrocarbon content of less than 53 wt-%, as measured according to ASTM D2425-04 (2011). The fuel blend is formed by mixing the at least two feedstocks together before subjecting them to the catalytic cracking and hydrotreatment, or by obtaining a first fuel component and at least one further fuel component from the catalytic cracking and hydrotreatment of the at least two feedstocks, and mixing the first fuel component and the at least one further fuel component together.
