一种烃裂化碱洗涤操作聚合反应的抑制剂
摘要：
本发明涉及一种抑制烃裂化工艺裂解气中醛、酮等羰基化合物、不饱和烯烃在碱洗过程中发生的聚合反应的抑制剂，该抑制剂由水溶性阻聚剂、水溶性抗氧剂、溶剂和水溶性分散剂组成；水溶性抗氧剂与水溶性阻聚剂摩尔比为1:2～20；水溶性阻聚剂与溶剂的摩尔比为1:1～100；分散剂与水溶性阻聚剂的摩尔比为1:1～20；水溶性分散剂选自CaCl2、CaF2、NaCl、NaF中的一种或几种的混合物；该抑制剂能有效抑制裂解气中醛、酮等羰基化合物、不饱和烯烃在碱洗过程中发生的聚合反应，并能溶解已经生成的聚合物。
摘要（英）：

The present invention relates to inhibitor which can inhibit the polyreaction of carbonyl compounds, such as aldehyde and ketone, and unsaturated olefin in the pyrolysis gas of the hydrocarbon cracking technique in the process of alkali cleaning. The inhibitor is composed of water-soluble polymerization inhibitor, water-soluble antioxidant, solvent and water-soluble dispersant; wherein, the molarratio of the water-soluble antioxidant and the water-soluble polymerization inhibitor is 1 : 2 to 20; the molar ratio of the water-soluble polymerization inhibitor and the solvent is 1 : 1 to 100; the molar ratio of the dispersant and the water-soluble polymerization inhibitor is 1 : 1 to 20; the water-soluble dispersant is selected from Ca Cl2, CaF2, NaCl or NaF or any combination thereof. The inhibitor can effectively inhibit the polyreaction of carbonyl compounds, such as aldehyde and ketone, and unsaturated olefin in the pyrolysis gas in the process of alkali cleaning, and can resolve theproduced polymers.
