Abstract: A method of transitioning from a first catalyst to a second catalyst in a gas phase fluidized bed reactor comprising continuously feeding the first catalyst and a recycle stream comprising olefin monomer to the reactor; wherein the monomer contacts the first catalyst in the fluidized bed and polymerizes; wherein the reactor is operating in condensing mode (withdrawing a gaseous stream comprising unreacted monomer from the reactor, cooling the gaseous stream to condense a portion thereof, and contacting the cooled gaseous stream with fresh monomer to form the recycle stream); and wherein a liquid phase of the recycle stream evaporates within the fluidized bed; discontinuing the first catalyst to the reactor while continuing to feed the recycle stream; maintaining the condensing mode in reactor at >3 wt. % liquid phase in recycle stream while no fresh catalyst is introduced to reactor; and introducing the second catalyst to the reactor operating in condensing mode.

Abstract: Processes for removing carbon disulfide from product streams containing a sulfide compound are performed by contacting the product stream with an alkanolamine and converting the carbon disulfide to a higher boiling point product, thereby reducing or eliminating carbon disulfide from the product stream. Subsequent removal of the higher boiling point product via distillation can lead to a purified sulfide stream with high purity.

Abstract: The present disclosure generally relates to processes to produce a mercaptan and an asymmetrical sulfide utilize stacked bed catalyst systems containing CoMo and NiMo, and these processes demonstrate a synergistic reduction in the amount of ethylene, methyl mercaptan, ethyl mercaptan, and H2S in product mixtures. In aspects, the conversion of limiting reactants in the synthesis of asymmetrical sulfides unexpectedly remain high under increased flow rates through the catalyst bed, and under reduced temperatures and pressures. In further aspects, reactor systems configured for the independent synthesis of mercaptans and asymmetrical sulfides in a single fixed bed catalyst vessel are also disclosed as a simplification of existing reactor systems employing separate reactors for separate mercaptan and sulfide syntheses.
