本文介绍在常压的实验室装置中,用14种不同的碱金属化合物,浸渍在含碳试样中作为催化剂,对碳——二氧化碳反应催化效应的实验结果。实验表明,含有重量13%碳酸钾的焦炭、无烟煤和炭黑(含碳试样:K_2CO_3=10:1.5)在800—900℃温度范围内获得了满意的气化结果;同不含有碳酸钾的试样在相同的二氧化碳转化率下进行比较,可以分别降低气化温度约300,300,200℃。试验证明:碱金属碳酸盐,碱金属氢氧化物和碳酸钠同四氧化三铁的复合剂,都表现出相接近的催化活性。另外,含碳试样的氯化,未获得明显的对二氧化碳的反应性。
This article describes the experimental results of a catalytic effect on the carbon-carbon dioxide reaction by impregnating carbon-containing samples with 14 different alkali metal compounds as a catalyst in an atmospheric laboratory apparatus. Experiments show that 13% of potassium carbonate containing coke, anthracite and carbon black (carbonaceous sample: K_2CO_3 = 10: 1.5) in the 800-900 ℃ temperature range to obtain a satisfactory gasification results; with no potassium carbonate The samples were compared at the same carbon dioxide conversion to reduce the gasification temperature by about 300, 300 and 200 ° C, respectively. Experiments show that: alkali metal carbonate, alkali metal hydroxide and sodium carbonate and ferric oxide composites, have shown close catalytic activity. In addition, chlorination of carbon-containing samples did not give significant reactivity to carbon dioxide.
