Abstract
According to one or more embodiments, petrochemical products may be formed from a hydrocarbon material by a method that includes separating crude oil into at least two or more fractions in an atmospheric distillation column, hydrotreating the atmospheric residue to form a hydrotreated atmospheric residue, combining steam with the hydrotreated atmospheric residue, and cracking at least a portion of the hydrotreated atmospheric residue in the presence of a first catalyst to produce a cracking reaction product.

A process for producing petrochemical products from a hydrocarbon material, the process comprising:
- separating crude oil into at least two or more fractions in an atmospheric distillation column, wherein one of the fractions is an atmospheric residue;
- hydrotreating the atmospheric residue to form a hydrotreated atmospheric residue;
- combining steam with the hydrotreated atmospheric residue such that the partial pressure of the hydrotreated atmospheric residue is reduced;
- and
- cracking at least a portion of the hydrotreated atmospheric residue in the presence of a first catalyst at a reaction temperature of from 500° C. to 700° C. to produce a cracking reaction product.
A process for producing a petrochemical product stream from a hydrocarbon material, the process comprising:
- separating a crude oil stream into at least two or more fractions in an atmospheric distillation column, wherein one of the fractions is an atmospheric residue stream;
- hydrotreating the atmospheric residue stream to form a hydrotreated atmospheric residue stream;
- combining steam with the hydrotreated atmospheric residue stream such that the partial pressure of the hydrocarbons in the hydrotreated atmospheric residue stream is reduced;
- and
- cracking at least a portion of the hydrotreated atmospheric residue stream in the presence of a first catalyst at a reaction temperature of from 500° C. to 700° C. to produce a cracking reaction product stream.
