摘要： A polymerization catalyst is formed by combining a metal halide compound, a solvent, an effective amount of water to reduce fines and increase particle size, and a transition metal compound to form a first catalyst component and mixing the first catalyst component with a precipitating agent. After mixing the first catalyst component and the precipitating agent, the mixture can be heated to a temperature higher than the mixing temperature to reduce polymer fines. In the alternative prepolymer can be deposited on the catalyst(s) in an amount effective to reduce polymer fines. Optionally the catalyst can be treated with a halide ion exchanging source. The catalyst can also be combined with an organometallic cocatalyst.

摘要： A process for desalting a crude oil comprises (1) injecting steam into the oil to form a steam-injected oil; (2) adding water to the steam-injected oil to form a mixture; (3) introducing the mixture to a desalter; (4) inducing the formation of aqueous phase and oil phase; and (5) separating the oil phase from the aqueous phase. Where there are two desalting stages for desalting crude oil, the process can be carried out in either the first stage or second stage, or both stages. The process can also be similarly employed in a multistage desalting process.
