本工作在1310～2020℃范国内,以碳管炉中甲烷的热解沉碳为对象,研究了温度,接触时间,s/v比等参数变化对沉积过程的影响,并从沉碳速度随温度的变化关系出发,讨论和提出了从沉碳速度直接计算活化能的新方法。当实验设计使甲烷热解沉碳过程能满足恒温流动体系稳态沉碳条件时, In this paper, the influence of temperature, contact time, s / v ratio and other parameters on the deposition process was studied for the carbon deposition in methane furnace at 1310 ~ 2020 ℃. Temperature and the relationship between the change, the discussion and proposed a new method of calculating activation energy directly from the carbon sink rate. When the experimental design makes the methanogenic pyrolysis and carbon sink process meet the steady state carbon sinking condition of the constant temperature flow system,
