Abstract
According to one more embodiments, petrochemical products may be produced from a hydrocarbon material by a process that may comprise separating the hydrocarbon material into at least a lesser boiling point fraction, a medium boiling point fraction, and a greater boiling point fraction. The process may further comprise cracking at least a portion of the lesser boiling point fraction and the medium boiling point fraction in a second reactor unit in the presence of a second catalyst at a reaction temperature of from 500° C. to 700° C. to produce a second cracking reaction product, wherein the lesser boiling point fraction enters the second reactor unit upstream of wherein the medium boiling point fraction enters the second reactor.
