  • Patent number: 11718800
    Abstract: The present disclosure relates to methods for preparing aviation fuel component from a feedstock containing fossil hydrotreating feed and a second feed containing esters of fatty acids and rosins, free fatty acids and resin acids. The method includes subjecting the feedstock to hydrotreatment reaction conditions to produce a hydrotreated stream, separating the hydrotreated stream to three fractions from which at least part the highest boiling fraction is subjected to hydrocracking reaction to produce a hydrocracked stream. At least part of the hydrocracked stream is admixed with at least part of the hydrotreated stream, and their admixture is processed further until desired conversion of the feedstock to the aviation fuel component is obtained.

  • Patent number: 11655422
    Abstract: 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).

  • Patent number: 11499104
    Abstract: 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.

  • Patent number: 11427782
    Abstract: A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material contains more than 20 ppm Cl. Exemplary methods include (a) providing the recycled or renewable organic material; (b) purifying the organic recycled or renewable organic material to obtain a purified recycled or renewable organic material, and (c) hydrotreating the purified recycled or renewable organic material in a presence of a hydrotreating catalyst at a temperature from 270 to 380° C. under pressure from 4 to 20 MPa and under continuous hydrogen flow; to obtain purified hydrotreated recycled or renewable organic material.
