Abstract
A process and apparatus 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 about 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; (c) separating said vapor phase from remaining non-volatiles; and (d) converting the separated vapor phase in a regenerative pyrolysis reactor system.

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.
A vaporized hydrocarbon feedstock for a regenerative pyrolysis reactor system wherein said vaporized feedstock is derived from a process comprising:
- (a) thermally cracking at least 60 wt. % of resid having a boiling point of at least 565° C. in a resid-containing 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.;
- and
- (b) separating said vapor phase from remaining non-volatiles.
