摘要
混氢天然气输氢技术是近年发达国家提出的氢气输送新方案。该技术利用现有的天然气管道设施,避免庞大的输氢管网建设投资,可望解决氢气规模化运输的难题。本文对混氢天然气技术的概念及其特点和关键技术问题进行介绍,并对相关技术包括氢气制备、管道改造、氢气分离、混氢天然气的使用进行综述。最后,对混氢天然气输氢的前景进行展望,并总结混氢天然气输氢需要解决的相关问题。
Using blended hydrogen natural gas to transport hydrogen is a novel technology proposed by developed countries in recent years.This technology utilizes existing natural gas pipeline facilities to avoid the large capital investment for the construction of hydrogen pipeline networks,and thus is expected to solve the problem of largescale hydrogen transportation.The concept,characteristics and key technical issues of blended hydrogen natural gas transportation were introduced.The related technologies,including hydrogen preparation,pipeline renovation,hydrogen separation and the use of blended hydrogen natural gas were summarized.Moreover,the potential of blended hydrogen natural gas transportation was prospected,and technical problems in blended hydrogen natural gas transportation were summarized.
