Abstract

A method of treating non-petroleum or renewable feedstock is carried out by introducing a non-petroleum or renewable feedstock containing gums and/or resins into a reactor at a flow velocity of from 20 ft/sec to 100 ft/sec. The feedstock is heated within the reactor to a temperature of from 700° F. to 1100° F. to convert the feedstock to a reactor product. The reactor product is cooled to form a cooled reactor product. Gases, metals, and water from the cooled reactor product are separated and removed to form a final product. The final product has a gum or resin content that is reduced by 10 wt % to 100 wt % by weight of the initial gum and resin content of the feedstock.

Claims (47)

1 . A method of treating non-petroleum or renewable feedstock containing gums and/or resins, the method comprising:

introducing a non-petroleum or renewable feedstock containing gums and/or resins into a reactor at a flow velocity from 20 ft/sec to 100 ft/sec, the feedstock being heated within the reactor to a temperature from 700° F. to 1100° F. to convert the feedstock to a reactor product;

cooling the reactor product to form a cooled reactor product; and

separating and removing gases, metals, and water from the cooled reactor product to form a final product, the final product having a gum or resin content that is reduced by 10 wt % to 100 wt % by weight of the initial gum and resin content of the feedstock.

2 . The method of claim 1 , wherein:

the feedstock has an oxygen content of 8 wt % or more by total weight of the feedstock.

3 . The method of claim 1 , wherein:

the feedstock has a metal content of 0.1 ppm to 5000 ppm by total weight of the feedstock.

4 . The method of claim 1 , wherein:

the feedstock contains gums and/or resins in a total amount from 10 wt % or more by total weight of the feedstock.

5 . The method of claim 1 , wherein:

the feedstock contains gums and/or resins in a total amount from 10 wt % to 30 wt % by total weight of the feedstock.

6 . The method of claim 1 , wherein:

the final product has an oxygen content that is 60% or less of that of the feedstock.

7 . The method of claim 1 , further comprising:

hydroprocessing the final product to form a hydroprocessed product.

8 . The method of claim 7 , wherein:

the hydroprocessed product has from 0.1 wt % or less oxygen by weight of the hydroprocessed product.

9 . The method of claim 7 , further comprising:

fractionating the hydroprocessed product into fractions comprising a naphtha fraction, a sustainable aviation fuel fraction, and a renewable diesel fraction.

10 . The method of claim 1 , further comprising:

fractionating the final product into fractions comprising a naphtha fraction, a sustainable aviation fuel fraction, and a renewable diesel fraction.

11 . The method of claim 10 , wherein:

hydroprocessing at least one of the fractions.

12 . The method of claim 1 , further comprising:

the final product is hydroprocessed and fractionated to form a refined product comprising at least one of a naphtha fraction, a sustainable aviation fuel fraction, and a renewable diesel fraction.

13 . The method of claim 12 , wherein:

the refined product comprises sustainable aviation fuel fraction having a freeze point of −40° F. or less, as measured by ASTM D2386.

14 . The method of claim 12 , wherein:

the refined product comprises sustainable aviation fuel fraction having a freeze point of −40° F. or less, as measured by ASTM D2386, a flash point of at least 100° F., as measured by ASTM D93, and a boiling end point of at least 300° C., as measured by ASTM D86.

15 . A method of treating non-petroleum or renewable feedstock containing gums and/or resins, the method comprising:

introducing a non-petroleum or renewable feedstock comprising gums and/or resins in a total amount of 10 wt % or more by total weight of the feedstock into a reactor at a flow velocity from 20 ft/sec to 100 ft/sec, the feedstock being heated within the reactor to a temperature from 700° F. to 1100° F. to convert the feedstock to a reactor product, wherein the feedstock has an oxygen content from 8 wt % or more by total weight of the feedstock and a metal content from 0.1 ppm to 5000 ppm by total weight of the feedstock;

cooling the reactor product to form a cooled reactor product;

separating and removing gases, metals, and water from the cooled reactor product to form a final product, the final product having a gum or resin content that is reduced by 10 wt % to 100 wt % by weight of the initial gum and resin content of the feedstock; and

performing at least one of:

(A) hydroprocessing the final product to form a hydroprocessed product; and

(B) fractionating the final product into fractions comprising a naphtha fraction, a sustainable aviation fuel fraction, and a renewable diesel fraction.

16 . The method of claim 15 , wherein:

the feedstock contains gums and/or resins in a total amount from 10 wt % to 30 wt % by total weight of the feedstock.

17 . The method of claim 15 , wherein:

step (A) is performed, and further comprising fractionating the hydroprocessed product of step (A) into fractions comprising a naphtha fraction, a sustainable aviation fuel fraction, and a renewable diesel fraction.

18 . The method of claim 15 , wherein:

step (B) is performed, and further comprising hydroprocessing at least one of the fractions of step (B).

19 . The method of claim 15 , wherein:

both steps (A) and (B) are performed to form a refined product comprising sustainable aviation fuel fraction having a freeze point of −40° F. or less, as measured by ASTM D2386.

20 . The method of claim 19 , wherein:

the refined product comprises sustainable aviation fuel fraction having a freeze point of 40° F. or less, as measured by ASTM D2386, a flash point of at least 100° F., as measured by ASTM D93, and a boiling end point of at least 300° C., as measured by ASTM D86.
