Process for preparing a polyethylene product in a loop reactor for polymerization

摘要

Abstract invention patent: "process to prepare a product of polyethylene in a loop reactor for polymerization.The present invention relates to a process for preparing polyolefin in a loop reactor for polymerization, in which the said reactor comprises: a plurality of loop pipes interconnected to define a flow path for an aqueous paste of polyolefin and one or more PE RNAs funnel provided in at least one horizontal part of said pipes interconnected.And the said process comprises the steps of: feeding of olefin monomer, diluent liquid, catalyst for polymerization.Optionally, hydrogen and optionally comonomer of olefin in the said loop reactor; and curing the said monomer olefin and optionally comonomer to produce said that folder aqueous polyolefin in reactor loop; when the speed of movement of the folder aquo SA polyolefin within at least a portion of said horizontal pipes interconnected with aOne or more legs funnel is reduced by at least 20% and at most 60% when compared to the speed of movement in the rest of the said loop reactor.
