Abstract: Systems and methods for processing a C4 and C5 stream are disclosed. A pygas stream can be separated in a depentanizer to produce a C4 and C5 stream and a C6 to C9+ stream. The C4 and C5 stream is further processed to recover C5 dienes including isoprene, pentadiene, cyclopentadiene, or combinations thereof. The C6 to C9+ stream is further processed to recover aromatics including benzene, toluene, xylene, ethylbenzene, or combinations thereof.

Abstract: Methods for catalytic cracking hydrocarbon mixture have been disclosed. A hydrocarbon mixture having an initial boiling temperature of 30° C. to 70° C. is catalytically cracked in the presence of a catalyst to produce one or more olefins and/or one or more aromatics. The catalytic cracking is conducted such that the amount of coke formed on the catalyst is at least 5 wt. % (based on total weight of spent catalyst). The catalyst from the catalytic cracking step is then regenerated to produce regenerated catalyst.

Abstract: 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.

Abstract: A system and method for processing pyrolysis gasoline is disclosed. The system and method involves separating a pyrolysis gasoline stream to produce a first stream comprising primarily un-hydrogenated C9+ compounds. The separating of the pyrolysis e gasoline occurs without hydrogenation being carried out on the pyrolysis gasoline before the separating.

Abstract: Methods for the selective hydrogenation of acetylenic compounds in a product stream that includes isoprene. A method of selectively hydrogenating an acetylenic hydrocarbon in the presence of isoprene may include obtaining a hydrocarbon mixture comprising an acetylenic hydrocarbon, isoprene, and butadiene or cyclopentadiene, or both. If cyclopentadiene is present, the hydrocarbon mixture may comprise greater than 2 wt. % cyclopentadiene. The method may further include contacting the hydrocarbon mixture and hydrogen (H2) with a hydrogenation catalyst under reaction conditions that are more selective to the hydrogenation of the acetylenic hydrocarbon than the isoprene.
