摘要: This invention is directed to processes of making polymer in the presence of a hydrofluorocarbon or perfluorocarbon and recovering the polymer. The processes provided enable polymerization processes to be practiced with minimal fouling in the reaction system, and to the recovery of the hydrofluorocarbon and other hydrocarbons such as hydrocarbons for reuse in the process or hydrocarbon by-products from the polymerization process. The invention is particularly beneficial in the production of ethylene based polymers using Ziegler Natta catalyst systems.

摘要: This invention is directed to a polymerization process that is carried out at relatively high productivity levels and with relatively low fouling. The process includes mixing together a catalyst system, at least one monomer and a hydrofluorocarbon to produce the polymer. The reaction is carried out such that little to no chlorine containing hydrocarbons are present.

摘要: In a process for converting methane to higher hydrocarbons including aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst in a reaction zone under conditions effective to convert said methane to aromatic hydrocarbons. A first portion of the catalyst is transferred from the reaction zone to a heating zone, where the first catalyst portion is heated by contacting the catalyst with hot combustion gases generated by burning a supplemental source of fuel. The heated first catalyst portion is then returned to the reaction zone.

摘要: A process for polymerizing one or more monomers is provided. In at least one specific embodiment, the process includes preparing a mixture comprising the one or more monomers, a catalyst system and a flourinated hydrocarbon, preferably a hydrofluorocarbon. A fluorinated hydrocarbon containing stream, a polymer product stream and a waste stream are recovered from the mixture. At least a portion of the waste stream is sent to a non-flare decomposition system to produce a destructed waste stream, and the destructed waste stream is released to atmosphere.
