Abstract
A method for pretreating and purifying crude bio-feedstocks intended for processes of transformation into biofuels is described, the method being characterized in that said the crude bio-feedstock is subjected, in the form of an aqueous emulsion to a heat treatment by passing it through a coil visbreaker furnace at a temperature greater than 100° C. and a pressure greater than 3 barg, possibly in an inert atmosphere, for a pre-established contact/residence time, the effluent exiting the reactor being subsequently subjected to at least a non-absorbent physical separation to separate the bio-feedstock from metal contaminants and phosphorus.
