摘要： A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material includes more than 1 ppm silicon as silicon compounds. Exemplary steps include (a) providing the recycled or renewable organic material; (b) heat treating the recycled or renewable organic material to form a heat treated recycled or renewable organic material, wherein the at least part of silicon compounds present in the recycled or renewable organic material are converted to volatile silicon compounds, and (c) evaporating volatile silicon compounds from the heat treated recycled or renewable organic material to obtain recycled or renewable organic material fraction containing less silicon than the recycled or renewable organic material provided in step (a).

摘要： 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.

摘要： A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material includes more than 1 ppm silicon as silicon compounds and/or more than 10 ppm phosphorous as phosphorous compounds. The method can include providing a feed of the lipid material; heat treating the organic material in presence of an adsorbent and the filtering organic material and hydrotreating the lipid material in a presence of a hydrotreating catalyst to obtain purified hydrotreated organic material having less than 20% organic material and/or less than 30% of the original phosphorous content of the organic material.
