Abstract

The thermal decomposition of precursors of Li/MgO catalysts prepared from different Mg and Li compounds is reported. Dehydration and dehydroxylation is observed in both cases, in addition to decomposition of LiNO3, but not of Li2CO3. The properties of the solids are related to the melting and spreading of LiNO3 or Li2CO3 before or after Mg(OH)2 dehydroxylation.

Abstract

Описывают термическое разложение прекурсоров катализаторов Li/MgO, приготовленных их различных соединений Mg и Li. Помимо разложения LiNO3, а не Li2CO3, в обоих случаях наблюдается дегидратация и дегидроксилирование. Свойства твердых веществ коррелируют с плавлением и распределением LiNO3 или Li2CO3 на поверхности перед или после дегидроксилирования Mg(OH)2.
