天然气化工副产氢的氢能应用及氢-氨融合发展分析OA北大核心CSTPCD

The conversion of by-product hydrogen form natural gas chemical industry from traditional chemical applications to hydrogen energy applications can achieve upgrading of by-product quality and is beneficial for the development of the hydrogen energy industry.The carbonyl synthesis gas and acetylene tail gas from natural gas chemical industry are separated and purified to produce high-quality hydrogen,which can be innovatively applied to hydrogen fuel cell vehicles.It was proposed that the by-product hydrogen could be upgraded to various high-quality hydrogen that meets the technical requirements of national standards to meet the application needs of industry,transportation,energy and construction hydrogen,and expand the application field of hydrogen energy.In response to the current difficulties of storage and transportation bottlenecks and cost constraints of hydrogen energy affecting its large-scale applications,it was proposed that natural gas chemical enterprises could also synthesize liquid ammonia from the by-product hydrogen to transform and apply it through hydrogen-ammonia fusion based on the characteristics of liquid ammonia as hydrogen storage medium and zero carbon fuel,as well as the obvious advantages of liquid ammonia compared to gas hydrogen and liquid hydrogen storage.What's more,the application scenarios and development prospects of liquid ammonia in traditional fuels,ammonia fuel cells and ammonia catalytic cracking for hydrogen production were analyzed.By-product hydrogen from natural gas chemical industry can break through traditional chemical applications and transform into hydrogen energy applications with good development prospects,playing a positive role in the field of new energy.
