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.
