Method for removing impurities from tetrahydrofuran

A process for removing one or more impurities from a tetrahydrofuran stream in a tetrahydrofuran polymerization process is provided. The process comprises the steps of: (a) providing a tetrahydrofuran input stream to a tetrahydrofuran polymerization process, the tetrahydrofuran input stream comprising one or more impurities; (b) contacting the tetrahydrofuran input stream with an adsorption medium, wherein the adsorption medium has an adsorption capacity for one or more impurities; (c) allowing adsorption of one or more impurities to the adsorption medium; (d) removing a tetrahydrofuran purified stream from the adsorption medium, the tetrahydrofuran purified stream comprising a lower concentration of impurities than in the input stream; (e) purifying the stream using tetrahydrofuran in the tetrahydrofuran polymerization process. 提供了一种用于在四氢呋喃聚合过程中从四氢呋喃流中去除一种或多种杂质的方法。该方法包括以下步骤：(a)向四氢呋喃聚合过程提供四氢呋喃输入流，该四氢呋喃输入流包含一种或多种杂质；(b)使该四氢呋喃输入流与吸附介质接触，其中该吸附介质对一种或多种杂质具有吸附能力；(c)允许一种或多种杂质吸附到吸附介质；(d)从吸附介质中去除四氢呋喃纯化流，该四氢呋喃纯化流包含浓度比输入
