Abstract
A method of treating non-petroleum or renewable feedstock containing lignins is carried out by introducing a lignin-containing feedstock 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 lignin-containing feedstock into a reactor product. The reactor product is cooled to form a cooled reactor product. At least one of gases, metals, and water are separated and removed from the cooled reactor product to form a final product. The final product has a lignin content that is reduced by 10% to 100% by weight of the initial lignin incorporated into the feedstock.
