Abstract: In order to improve the regeneration performance of methyl nitrite (MN) and to reduce the production of by-product nitric acid, a high gravity-reactor was adopted to study the regeneration process of nitric oxide (NO) oxidative esterification synthesis of MN. The effects of operating conditions, including gas inlet mode, reaction temperature, molar ratios of CH3OH to NO, and NO to O2 on the yield of MN were investigated, and the appropriate process conditions were obtained. The results showed that MN yield reached more than 96% at atmosphere pressure when NO and O2 were fed into the reactor separately and mixed at the reaction temperature 30-50 ℃, molar ratio of CH3OH to NO 2-6, molar ratio of NO to O2 5-7. The pilot tests showed that the results of small scale trials have magnified guiding significance for the scale design and process operation of the MN regeneration. Key words: high gravity; methyl nitrite; reactor; regeneration

未来五年美国将引领全球新增乙烯产能

全球数据咨询公司（GlobalData）称，2018年至2022年期间，美国是全球新增乙烯产能最多的国家，将新增1×107 t/a的乙烯产能，排名第二的是中国，将新增8×106 t/a，排名第三的是伊朗，将新增6×106 t/a。

从目前已经宣布的计划而言，2022年前美国拟建的新增乙烯产能将占到全球新增乙烯产能的33%。美国将新建8个乙烯项目，其中，台塑公司位于美国德克萨斯州波因特康福特3号乙烯装置和埃克森美孚公司贝城2号乙烯装置的设计产能最大，均为2.3×106 t/a。

2022年，预计中国将占全球乙烯新增产能的27%，该国有18个拟建乙烯项目；预计伊朗将占全球乙烯新增产能的19%，该国有9个拟建乙烯项目；俄罗斯将占全球乙烯产能的7%，该国只有2个拟建乙烯项目；位于第5位的是马来西亚、越南、阿曼和委内瑞拉，各新增产能1×106 t/a，占2022年全球乙烯计划总产能的3%。
