Abstract

The embodiment of the invention provides an ammonia cracking hydrogen production and hydrogenation comprehensive energy supply system, and relates to the technical field of ammonia energy utilization. The ammonia cracking hydrogen production and hydrogenation comprehensive energy supply system comprises an ammonia storage tank, an ammonia evaporator, an ammonia preheater, a self-heating ammonia cracking reactor, an air preheater, a superheater, a vaporizer, a fuel mixing tank and a co-production unit; the comprehensive energy supply system for hydrogen production and hydrogenation through ammonia cracking can realize comprehensive and efficient supply of various energy forms of hydrogen, electricity, heat and cold by scientifically and reasonably coupling electricity, heat and cold flows in process links such as ammonia evaporation, ammonia cracking, ammonia separation, hydrogenation and ammonia combustion based on a hydrogen carrier and an energy carrier.

Description

technical field [0001] The invention relates to the technical field of ammonia energy utilization, in particular to a comprehensive energy supply system for hydrogen production and hydrogenation by ammonia cracking. Background technique [0002] The development of hydrogen energy has received great attention because it can be applied to the decarbonization of difficult-to-electrify fields such as heavy industry and heavy-duty transportation, and it can help large-scale renewable energy consumption such as wind and rain. Vehicle hydrogenation is currently the most important way of hydrogen energy application. For the development of hydrogen energy, the low volumetric energy density of hydrogen and the high cost of storage and transportation are the main bottlenecks. [0003] As one of the compounds with the highest hydrogen mass fraction (about 17%), ammonia is easy to store and transport (ammonia can be liquefied when it is lower than about -33°C at normal pressure or highe...
