Abstract:
1. A process for preparing a resid-containing hydrocarbon feedstock for use in a regenerative pyrolysis reactor, comprising: (a) feeding a resid-containing hydrocarbon feedstock to a thermal cracking unit; (b) thermally cracking at least 60 wt. % of said resid having a boiling point of at least 565° C. in said hydrocarbon feedstock to form a vapor phase containing cracked hydrocarbons, based upon the total weight of said hydrocarbon feedstock having a boiling point of at least 565° C.; (c) separating said vapor phase from remaining non-volatiles; and (d) converting the separated vapor phase in a regenerative pyrolysis reactor system into a pyrolysis product.
