阅读说明：本技术 用于催化生产尿素的方法 (Process for the catalytic production of urea ) 是由 叶夫根尼·马欣亚 塔里克·埃尔豪阿里 克里斯托夫·格洛茨巴赫 尼尔斯·腾洪堡 沃尔特·莱特纳 于 2020-04-27 设计创作，主要内容包括：本发明涉及一种用于制备尿素的方法,所述方法包括：a)基于二氧化碳、氢气和氨制备甲酰胺,其中在催化反应中形成甲酸甲酯或甲酸铵作为中间体,以及b)通过在催化剂存在下使所述所得甲酰胺反应或使所述所得甲酰胺与氨反应来制备尿素,其中二氧化碳的来源是载有化学和/或物理结合的二氧化碳的液体,并且选自甲醇相或氨水溶液,所述液体是通过使用洗涤流体对合成气进行气体洗涤以去除CO-(2)而获得的。本发明的方法可以与氨合成结合,在这种情况下,在所述氨合成操作中只需要微小的修改。(The present invention relates to a process for the preparation of urea, said process comprising: a) preparing formamide on the basis of carbon dioxide, hydrogen and ammonia, wherein methyl formate or ammonium formate is formed as an intermediate in a catalytic reaction, and b) preparing urea by reacting the resulting formamide in the presence of a catalyst or reacting the resulting formamide with ammonia, wherein urea is oxidizedThe source of carbon is a liquid loaded with chemically and/or physically bound carbon dioxide and selected from a methanol phase or an aqueous ammonia solution, said liquid being obtained by gas scrubbing of syngas with a scrubbing fluid for removal of CO 2 And then obtaining the product. The process of the invention may be combined with ammonia synthesis, in which case only minor modifications are required in the ammonia synthesis operation.)
