Heat treatment with adsorption purification of organic material of biological origin

Abstract

The present disclosure provides a method of purifying an organic material of biological origin, which includes providing a feedstock containing organic material of biological origin; purifying the feedstock in a pre-treatment step including heating the feedstock in a presence of an adsorbent at a temperature of at least 150° C., to obtain a heat-treated feedstock; filtering the heat-treated feedstock to remove adsorbent and to obtain a purified feedstock; and optionally subjecting the purified feedstock to further processing, wherein the purifying is performed in a cone vessel having a first cross sectional area in an upper part of the vessel which decreases downwards to a second cross sectional area, which is smaller than the first cross sectional area.
