Systems and methods for recovering cyclopentadiene and/or isoprene from a mixture comprising C.sub.5 hydrocarbons are disclosed. A C.sub.5 mixture comprising cyclopentadiene and/or isoprene is flowed into a dimerization unit to form dimers. The dimers are then separated from the unreacted C.sub.5 hydrocarbons. The separated dimers are monomerized to form a stream comprising cyclopentadiene and/or isoprene, which is subsequently separated to form a first product stream comprising primarily isoprene and a second product stream comprising primarily cyclopentadiene.

Systems and methods for producing dicyclopentadiene via thermal dimerization of cyclopentadiene. The feed stream comprising cyclopentadiene is flowed through four shell and tube heat exchangers in series. Each of the shell and tube heat exchangers comprise a shell and one or more tubes disposed in the shell. The feed stream is flowed in the tubes while the heat transfer medium is flowed in the shell to absorb the exothermic heat released by the dimerization of cyclopentadiene in the tubes. In this way, the temperature in the tubes is controlled at a level where the conversion rate of cyclopentadiene is above 99% and the occurrence of runaway reaction is substantially prevented.

Systems and methods for producing dicyclopentadiene from cyclopentadiene using reactive jet mixing are disclosed. A C.sub.5 hydrocarbon mixture that comprises cyclopentadiene (C.sub.5H.sub.6) is injected as a jet stream into C.sub.5 hydrocarbon liquid in a reactor tank. Under appropriate reaction conditions, cyclopentadiene is dimerized to form dicyclopentadiene.
