  • Process for producing a saturated hydrocarbon component
    Publication number: 20070131579
    Abstract: The invention relates to a process for producing high-quality saturated base oil or a base oil component based on hydrocarbons. The process of the invention comprises two main steps, the oligomerization and deoxygenation. A biological starting material containing unsaturated carboxylic acids and/or esters of carboxylic acids is preferably used as the feedstock.

  • Process for the manufacture of hydrocarbons
    Publication number: 20070135669
    Abstract: A feedstock originating from renewable sources is converted to branched and saturated hydrocarbons without heteroatoms in the diesel fuel distillation range by skeletal isomerisation and deoxygenation carried out by hydrodeoxygenation or alternatively by combined decarboxylation and decarbonylation reactions, whereby the consumption of hydrogen is decreased.
