摘要
“双碳”背景下天然气裂解制氢越来越受到重视,有望成为未来天然气达峰后继续发挥天然气产业基础设施优势、与新能源融合发展的重要方向。国内外对天然气裂解制氢的研究集中在固定床催化裂解制氢技术方向,但面临催化剂积炭失活、生产不连续和工程化放大困难等问题,难以实现工业化。一种新型熔融金属天然气裂解制氢技术有望能够解决这些难题,使规模化天然气催化裂解成为可能。总结了目前天然气催化裂解制氢的研究现状,从技术原理、经济性与竞争力、工程化挑战与技术难点等方面介绍了熔融金属天然气裂解制氢技术。分析认为,熔融金属天然气裂解制氢能从原理上解决裂解制氢催化剂积炭失活、生产不连续的难题,有望成为天然气零碳排放制氢的突破方向,发展前景广阔。
Under the“Dual Carbon”background,hydrogen production from natural gas cracking has been paid more and more attention,which is expected to become an important direction to continue to play the advantages of natural gas industry infrastructure and promote the integrated development of new energy after the peak of natural gas.The research on hydrogen production from natural gas cracking at home and abroad focuses on the technology direction of fixed bed catalytic cracking,but it is difficult to realize industrialization due to the problems of catalyst carbon deposition deactivation,discontinuous production and engineering amplification difficulties.A new technology of hydrogen production from molten metal natural gas cracking is expected to solve these problems and make large-scale natural gas catalytic cracking possible.The current research status of hydrogen production from natural gas catalytic cracking at home and abroad was summarized,the technology of hydrogen production from molten metal natural gas cracking in terms of technical principle,economy and competitiveness,engineering challenges and technical difficulties was introduced.The conclusion is that hydrogen production from molten metal natural gas cracking can solve the problems of catalyst carbon deposition deactivation and discontinuous production in principle,and is expected to become a breakthrough direction of hydrogen production from natural gas without carbon emission,with broad prospects for development.
