Abstract
A hydrocarbon material may be processed by a method that includes separating the hydrocarbon material into at least a lesser boiling point fraction, a medium boiling point fraction, and a greater boiling point fraction. The method may further include steam cracking at least a portion of the lesser boiling point fraction, catalytically cracking at least a portion of the medium boiling point fraction, and hydrocracking at least a portion of the greater boiling point fraction.
Claims19
A method for processing hydrocarbon material, the method comprising:
- separating the hydrocarbon material into at least a lesser boiling point fraction, a medium boiling point fraction, and a greater boiling point fraction, wherein a cut point between the lesser boiling point fraction and the medium boiling point fraction is from 280° C. to 320° C., and wherein a cut point between the medium boiling point fraction and the greater boiling point fraction is from 520° C. to 560° C.;
- steam cracking at least a portion of the lesser boiling point fraction;
- catalytically cracking at least a portion of the medium boiling point fraction;
- and
- hydrocracking at least a portion of the greater boiling point fraction,
A method for processing hydrocarbon material, the method comprising:
- separating the hydrocarbon material into at least a lesser boiling point fraction, a medium boiling point fraction, and a greater boiling point fraction, wherein the lesser boiling point fraction has a final boiling point of from 280° C. to 320° C., wherein the medium boiling point fraction has an initial boiling point of from 280° C. to 320° C. and has a final boiling point of from 520° C. to 560° C., wherein the greater boiling point fraction has an initial boiling point of from 520° C. to 560° C., wherein a cut point between the lesser boiling point fraction and the medium boiling point fraction is from 280° C. to 320° C., and wherein a cut point between the medium boiling point fraction and the greater boiling point fraction is from 520° C. to 560° C.;
- steam cracking at least a portion of the lesser boiling point fraction;
- catalytically cracking at least a portion of the medium boiling point fraction;
- and
- hydrocracking at least a portion of the greater boiling point fraction.
