天然气制氢工艺现状及发展

Present Situation and Development of Hydrogen Production from Natural Gas

天然气制氢气常用于大规模的氢气供应场合,在天然气丰富的地区,天然气制氢是最好的选择。然而天然气水蒸汽重整制氢需吸收大量的热,制氢过程能耗高,燃料成本占生产成本的52%～68%,天然气价格仍是上涨的趋势,反应需要昂贵的耐高温不锈钢管作反应器。因此,开发和改进更为先进的天然气制氢新工艺技术是解决廉价氢源的方向。

Natural gas to hydrogen was commonly used in large- scale hydrogen supply occasions. In the gas- rich regions, natural gas to hydrogen high energy consumption during was the best choice. However, natural gas steam reforming needed to absorb a lot of heat the production, fuel costs accounted for 52% -68% of the production, increasing natural gas prices was the trend, and the response needed for expensive high temperature resistance stainless steel tube as the re- action device, therefore, the development and improvement of the more advanced new technol%,y for natural gas to hydro- gen was the direction to solve the low - cost source of hydrogen.
