煤制天然气工艺及甲烷化催化剂研究进展

Research progress in process of coal to natural gas and methanation catalysts

随着人们生活水平的不断提高以及世界工业的高速发展,作为一种高效清洁能源,天然气的需求越来越大,中国在较长时间内将会出现供不应求的局面。煤制天然气技术的大力发展不仅可有效缓解中国的能源危机,而且可有效地改善中国的环境状况。综述了煤制天然气的现状,包括国内外煤制天然气工艺技术的发展现状以及甲烷化催化剂研究现状。重点介绍了甲烷化催化剂的活性组分、助剂及载体方面的研究进展,提出了中国煤制天然气技术所面临的机遇与挑战。

As one kind of high efficient and clean energy,natural gas is increasingly required with the improvement of people′s living standard and the rapid development of world industry.Demand of natural gas will exceed supply for a long time in China.As a kind of coal clean utilization,vigorous development of coal to natural gas technology can not only effectively ease energy crisis,but also improve the environment situation in China.The current situation of coal to natural gas,including the development progress of coal to natural gas technology at home and abroad and research status of methanation catalysts was summarized.The progress of active sites,additives,carriers,and also the opportunity and challenge of coal to natural gas in China were introduced emphatically.
