Abstract
Methods and systems for recovering dicyclopentadiene from pygas are provided. Methods can include heating pygas to generated heated pygas, recovering a C5 fraction from the heated pygas, and dimerizing cyclopentadiene from the C5 fraction to form dicyclopentadiene. Methods can further include recovering the C5 fraction from the pygas in a depentanizer column. Other methods can include heating pygas including dicyclopentadiene to form cyclopentadiene and hydrogenating cyclopentadiene in the pygas to form cyclopentane.
Claims12
A method of recovering dicyclopentadiene from pygas, the method comprising:
- (a) heating the pygas to generate heated pygas;
- (b) recovering a C5 fraction from the heated pygas;
- and
- (c) dimerizing cyclopentadiene from the C5 fraction to form dicyclopentadiene;
- wherein the heating comprises heating the pygas in a thermal reactor for about 1 to about 3 hours at a temperature of about 170° C. to about 190° C.;
- and
- wherein the heating further comprises heating the pygas at a pressure of about 13 to about 16 bar.
A method of producing cyclopentane from pygas comprising dicyclopentadiene, the method comprising:
- (a) heating the pygas to form cyclopentadiene in a thermal reactor for about 1 to about 3 hours at a temperature of about 170° C. to about 190° C. at a pressure of about 13 to about 16 bar;
- and
- (b) hydrogenating the cyclopentadiene to form cyclopentane.
