阅读说明：本技术 制备亚乙基胺的方法 (Process for preparing ethyleneamines ) 是由 R·H·贝本塞 T·海德曼 B·贝克尔 E·科赫 H·鲁肯 J-P·梅尔德 于 2018-05-24 设计创作，主要内容包括：本发明涉及一种在液相中制备链烷醇胺和/或亚乙基胺的方法,包括使乙二醇和/或单乙醇胺与氨在包含一种或多种选自Sn和元素周期表第8、9、10和11族元素的活性金属的胺化催化剂存在下反应。所述制备链烷醇胺和/或亚乙基胺的方法的特征在于,胺化催化剂是通过催化剂前体的还原煅烧方法获得的。催化剂前体优选通过使常规或催化载体材料与一种或多种活性金属的可溶化合物以及任选地一种或多种催化剂添加剂元素的可溶化合物接触而制备。本发明进一步涉及一种制备胺化催化剂的方法,所述胺化催化剂包含一种或多种选自Sn和元素周期表第8、9、10和11族元素的活性金属,其中所述胺化催化剂通过催化剂前体的还原煅烧方法获得。所述制备胺化催化剂的方法的特征在于,在其中进行催化剂前体的还原煅烧方法的反应器连接至脱硝系统。本发明还涉及脱硝系统在胺化催化剂的制备中的用途。(The invention relates to a method for producing alkanolamines and/or ethyleneamines in the liquid phase, comprising reacting ethylene glycol and/or monoethanolamine with ammonia in the presence of an amination catalyst comprising one or more active metals selected from Sn and elements of groups 8, 9, 10 and 11 of the periodic Table of the elements. The method for producing alkanolamines and/or ethyleneamines is characterized in that the amination catalyst is obtained by a method of reductive calcination of a catalyst precursor. The catalyst precursor is preferably prepared by contacting a conventional or catalytic support material with soluble compounds of one or more active metals and optionally soluble compounds of one or more catalyst additive elements. The invention further relates to a process for preparing an amination catalyst comprising one or more active metals selected from Sn and elements of groups 8, 9, 10 and 11 of the periodic table of the elements, wherein the amination catalyst is obtained by a process of reductive calcination of a catalyst precursor. The method for preparing an amination catalyst is characterized in that a reactor in which a reductive calcination method of a catalyst precursor is performed is connected to a denitration system. The invention also relates to the use of the denitrification system in the preparation of amination catalysts.)
