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.

Fuel composition for a diesel engine

The invention relates to a new base stock material. Specifically the invention relates to a saturated hydrocarbon composition and particularly to a composition based on biological raw materials, to be used as a high-quality base oil or to be used as a component in the production of a base oil having a high viscosity index and good low temperature properties. The composition contains saturated hydrocarbons and has a narrow carbon number range.

Base oil

The invention relates to a process for producing a hydrocarbon component of biological origin. The process comprises at least two steps, the first one of which is a HDO step and the second one is an isomerization step operated using the counter-current flow principle. A biological raw material containing fatty acids and/or fatty acid esters serves as the feed stock.

Process for producing a hydrocarbon component of biological origin

The invention relates to a method for separating materials of two different phases from one another and an assembly for implementing the method. According to one embodiment of the invention, the second phase having the material in suspended or dispersed form is separated from the first phase by centrifugal force. At least one separator comprises a multiport cyclone into which the material flow is passed via an infeed nozzle having an annular cross section.
