Abstract

The results of studying the effect of temperature and pressure on conversion of methane and the catalyst lifetime during the catalytic decomposition of methane with the formation of hydrogen and nanofibrous carbon on a Ni–Cu catalyst are presented. The pressure varied in the range of 1–10 atm at the temperatures of 600 and 675°C. It was found that when increasing pressure, the total yield of hydrogen increases from the start of synthesis to the deactivation of the catalyst. This effect is manifested the stronger, the higher the temperature of process. It is shown that increasing pressure allows expanding the temperature range of the process without reducing the total yield of useful products.

甲烷催化分解过程中温度和压力对甲烷转化率和催化剂寿命的影响

摘要

提出了研究温度和压力对甲烷转化率和在Ni-Cu催化剂上形成氢和纳米纤维碳的甲烷催化分解过程中催化剂寿命的影响的结果。在600和675°C的温度下,压力在1-10 atm的范围内变化。发现当增加压力时,从合成开始到催化剂失活,氢的总产率增加。该作用表现为越强,过程温度越高。结果表明,增加压力可以扩大工艺的温度范围,而不会降低有用产品的总产量。
