Abstract
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.
Claims35
A process for producing a hydrocarbon component of biological origin, comprising:
- providing a biological component to be hydrogenated;
- subjecting the biological component to be hydrogenated to prehydrogenation prior to the hydrodeoxygenation step;
- hydrodeoxygenating the biological component;
- and
- subjecting the hydrodeoxygenated biological component to isomerization, wherein
- the isomerization step operates using the counter-current flow principle, and wherein
- the biological component comprises fatty acids and/or fatty acid esters.
