摘要： In a process for producing phenol and cyclohexanone, a feed comprising cyclohexylbenzene is oxidized to produce an oxidation reaction product comprising cyclohexyl-1-phenyl-1-hydroperoxide. At least a portion of the oxidation reaction product is then cleaved to produce a cleavage reaction product comprising phenol, cyclohexanone, and at least one contaminant. At least a portion of the cleavage reaction product is contacted with an acidic material to convert at least a portion of the at least one contaminant to a converted contaminant and thereby produce a modified reaction product. The oxidation reaction product may have at least 50 wt% of cyclohexylbenzene, no greater than 80 wt% of cyclohexyl-1-phenyl-1-hydroperoxide, and 0.1 wt% to 10 wt% of another hydroperoxide.

摘要： A process for cracking a hydrocarbon feedstock containing salt and/or particulate matter, wherein said hydrocarbon feedstock containing salt and/or particulate matter is heated, then separated into a vapor phase and a liquid phase by flashing in a flash separation vessel, separating and cracking the vapor phase which comprises less than about 98% of the hydrocarbon feedstock containing salt and/or particulate matter, and recovering cracked product. The salt and/or particulate matter are removed in the liquid bottoms stream from the flash separation vessel. The liquid phase could then be sold as bunker C fuel oil or fed to a refinery catalytic cracker or coker unit without desalting.

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.
