Abstract

The strong and irreversible chemisorption of substrate or (and) reaction products („self-poisoning” of catalyst surface) has been found to account for an activity decrease and changes in catalytic selectivity in the reaction. The mechanism of 1,2-dichloroethane (1,2-DCE) decomposition has been discussed.

Abstract

Была исследована модификация каталитической активности и селективности в разложении 1,2-дихлорэтана (1,2-ДЦЭ), вводимого последовательными импульсами в микрореактор, соединенный с газовым хроматографом. Было найдено, что сильная необратимая — в исследованных экспериментальных условиях — хемосорбция субстрата или (и) реакционных продуктов («самоотравление» поверхности катализатора) вызывает понижение активности и измемения в каталитической селективности реакции. Обсуждается механизм разложения 1,2-ДХЭ.
