Description
Известна очистка двуокиси углерода от горючих примесей (водорода и окиси углерода) окислением их на палладиевом катализаторе. Таким образом двуокись углерода очищают только от водорода и окиси углерода.Known purification of carbon dioxide from combustible impurities (hydrogen and carbon monoxide) by oxidizing them on a palladium catalyst. Thus, carbon dioxide is purified only from hydrogen and carbon monoxide.
С целью наиболее полной очистки двуокиси углерода, предложен способ, по которому горючие примеси удал ют из двуокиси углерода окислением их на палладиево-рутениевом катализаторе, что позвол ет очищать двуокись углерода также от метана и других углеводородов. Кроме того, палладиево-рутениевый катализатор, по сравнению с нлатиновым , дещевле, обладает больщой активностью , устойчив против сернистых соединений .For the purpose of the most complete purification of carbon dioxide, a method has been proposed by which combustible impurities are removed from carbon dioxide by oxidizing them with a palladium-ruthenium catalyst, which also allows purification of carbon dioxide from methane and other hydrocarbons. In addition, the palladium-ruthenium catalyst, in comparison with nlatinum, is much more active, resistant to sulfur compounds.
Пример. Предварительно нагретую доExample. Preheated to
85-200 С газовую смесь подают в реактор, где при температуре 85-300°С на палладиево-рутениевом катализаторе (носитель - окись алюмини ) происходит полное окисленне водорода, окиси углерода и метана до углекислоты и воды. Степень очистки почти. от всех горючих примесей: метана, окиси углерода и водорода.85-200 C gas mixture is fed to the reactor, where at a temperature of 85-300 ° C, the palladium-ruthenium catalyst (carrier - alumina) is fully oxidized with hydrogen, carbon monoxide and methane to carbon dioxide and water. The degree of purification is almost. from all combustible impurities: methane, carbon monoxide and hydrogen.
Предмет изобретени Subject invention
Способ очистки двуокиси углерода от горючих примесей (водорода, окиси углерода) путем окислени их на катализаторе на основе паллади , отличающийс тем, что, с целью наиболее полной очистки от метана и других углеводородов, в катализатор ввод т рутений.A method of purifying carbon dioxide from combustible impurities (hydrogen, carbon monoxide) by oxidizing them on a palladium-based catalyst, characterized in that ruthenium is introduced into the catalyst in order to achieve the most complete purification from methane and other hydrocarbons.
