Abstract
Systems and methods for producing dicyclopentadiene from cyclopentadiene using reactive jet mixing are disclosed. A C5 hydrocarbon mixture that comprises cyclopentadiene (C5H6) is injected as a jet stream into C5 hydrocarbon liquid in a reactor tank. Under appropriate reaction conditions, cyclopentadiene is dimerized to form dicyclopentadiene.
Claims17
A method of producing dicyclopentadiene (C10H12), the method comprising:
- flowing a C5 hydrocarbon mixture stream that comprises cyclopentadiene (C5H6) to a tank;
- and
- injecting the C5 hydrocarbon mixture stream as a jet stream into a C5 hydrocarbon liquid in the tank at a velocity in a range from 1 m/s to 10 m/s and under reaction conditions sufficient to dimerize the cyclopentadiene to form dicyclopentadiene,
- wherein the injecting causes mixing of the C5 hydrocarbon mixture stream and the C5 hydrocarbon liquid,
- wherein the reaction conditions include a residence time of 180 to 1800 minutes, and
- wherein the jet stream is injected in a tank having a vertical height L and a diameter or width D such that a ratio of L to D is in a range of 0.5 to 1.5.
