Disclosed herein is a process for upgrading a raffinate butene (C4 Raffinate) stream to propylene which can produce polymer grade propylene (PGP) by a metathesis process, without consuming fresh ethylene as a feedstock. By recycling ethylene byproduct in the metathesis equilibrium, propylene selectivity can be further improved without negatively impacting butene conversion. Additionally, upon PGP separation, this technology can provide an effluent acceptable for alkylate production by achieving a balanced butene conversion and heavies coproduction. The disclosed process is a relatively low temperature process which can be deployed as a drop-in option for conventional ethylene/butene metathesis unit and provide additional flexibility to existing operations to balance the supply and demand of C2-C4 light olefins.

Process for converting raffinate butenes to propylene

Methods of converting isobutylene to C5+ compounds. The methods may include contacting isobutylene with a skeletal isomerization catalyst to provide a mixture of Colefins, and then contacting the mixture of Colefins with a metathesis catalyst to convert the mixture of Colefins to a product mixture. The product mixture may include Colefins.

Methods for isobutylene conversion to C5+ compounds

A winterized paraffin inhibitor, which is capable of being used for preventing the deposition of paraffins in hydrocarbon streams and capable of withstanding freezing or crystallization at freezing or sub-freezing temperatures, may be formed by adding an oxyalkylated branched aliphatic compound having 12 or more carbons to a high molecular weight aliphatic polymer paraffin inhibitor, the oxyalkylated branched aliphatic compound having 12 or more carbons being produced by the oxyalkylation of the branched aliphatic compound having 12 or more carbon atoms in which the branched aliphatic compound having 12 or more carbon atoms is grafted with a polyether via a ring-opening reaction, wherein the polyether is a polymer of ethylene oxide, propylene oxide, butylene oxide, and combinations thereof.
