    Abstract: The present disclosure provides a process for producing hydrocarbons from a feedstock containing organic material of biological origin. The process includes: providing a feedstock containing organic material of biological origin; pre-treating the feedstock in one or more pre-treatment stages to obtain a purified feedstock; subjecting the purified feedstock to pre-hydrotreatment to obtain a stream of partly hydrotreated feed; subjecting the stream of partly hydrotreated feed to hydrotreatment to obtain a stream of hydrocarbons; distilling the stream of hydrocarbons to obtain at least two fractions, a first heavy bottom fraction which is removed from the process, and a second middle fraction, which is collected for further processing; and subjecting the collected middle fraction to isomerisation to obtain an isomerised stream of hydrocarbons.

    Abstract: A method is disclosed of producing hydrocarbons from a recycled or renewable organic material wherein the recycled or renewable organic material contains hydroxyaromatic hydrocarbon compounds. Exemplary methods include (a) providing recycled or renewable organic material; (b) optionally purifying the recycled or renewable organic material; (c) hydrotreating the recycled or renewable organic material in a presence of a hydrotreating catalyst, thereby forming a hydrocarbon stream and a phenol-containing effluent; (d) separating phenols from the phenol-containing effluent of step (c), thereby forming a phenol stream and a purified water stream; and (e) recycling the phenol stream obtained in step (d) to step (c) to increase the yield of hydrocarbons obtained from step (c); to obtain hydrocarbons containing less than 1 wt % oxygen.
