国内外已有将活性炭用作催化剂担体的大量报导,阐述了其中无机物对某些反应的催化作用。例如,Walker对无机物在碳气化反应中的催化作用作了全面的回顾,Mcke总结了无机物对碳-氧,碳-二氧化碳,碳-水,碳-氢等反应的催化行为。研究的温度范围在550℃以上,原料大都采用纯净的石墨或糖炭,反应后产品组成复杂。用活性炭作为催化剂担体,同时又将它作为还原剂用于惰性气体的低温脱氧是本文中探讨的问题。目前,国内外气体脱氧都需要采取加氢或高温的手段,在气量不大的装置上就显得复杂些。在我们过去的实验中曾发现钯有促进碳纤维烧蚀的现象,故认为在碳上担载金属氧化物有可能使之在较低温度下与氧反应以脱除气体中的氧。本文报导这方面的试验结果。众所周知,碳在高温下与氧反应生成二氧化碳和一氧化碳。当碳上载有某些金属化合物时,可以降低其反应温度,显然反应产品的组成也会随之而改变。为此,选择某些 A great deal of reports have been made on the use of activated carbon as a catalyst carrier at home and abroad, and the catalytic action of inorganic substances on certain reactions has been described. For example, Walker made a comprehensive review of the catalysis of inorganic compounds in carbon gasification. Mcke summarized the catalytic behavior of inorganic compounds on carbon-oxygen, carbon-carbon dioxide, carbon-water, and carbon-hydrogen reactions. The temperature range of the study is above 550 ° C, most of the raw materials are pure graphite or sugar and the product composition is complicated after the reaction. The use of activated carbon as a catalyst support, and at the same time as a reducing agent for inert gas deoxygenation is the issue discussed in this article. At present, both domestic and international gas deoxidation need to take the means of hydrogenation or high temperature, and it is more complicated on the device with less gas. It has been found in our previous experiments that palladium promotes carbon fiber ablation and therefore it is considered that carrying a metal oxide on carbon makes it possible to react with oxygen at a lower temperature to remove oxygen from the gas. This article reports the test results in this area. It is well known that carbon reacts with oxygen at high temperatures to produce carbon dioxide and carbon monoxide. When some metal compounds are supported on carbon, the reaction temperature can be lowered. Obviously, the composition of the reaction product also changes. To do this, choose some
