1. A method of treating non-petroleum or renewable feedstock containing lignins, the method comprising:
introducing a lignin-containing feedstock into a reactor at a flow velocity of from 20 ft/sec to 100 ft/sec, the feedstock being heated within the reactor to a temperature of from 700° F. to 1100° F. to convert the lignin-containing feedstock into a reactor product;
cooling the reactor product to form a cooled reactor product; and
separating and removing at least one of gases, metals, and water from the cooled reactor product to form a final product, the final product having a lignin content that is reduced by 10% to 100% by weight of the initial lignin incorporated into the feedstock.
