Problems solved by technology

[0004] For one of the main problems of the hydrogen economy, "hydrogen storage and transportation", the hydrogen storage rate of the metal hydride currently used is too low, the energy consumption of high-pressure tank hydrogen storage is too high, and there are also problems in safety. At the same time, the investment in its hydrogen charging infrastructure Huge, therefore, the present invention proposes a safe and economical transport method for hydrogen

Embodiment Construction

[0020] Such as Figure 1-2 As shown, the hydrogen obtained from coke oven gas separation is purified and separated, mixed with a certain proportion of nitrogen, and sent to the general ammonia synthesis device in the prior art, at 700 ° C and 500 atmospheric pressure, under the action of iron catalyst synthetic ammonia. Then liquid ammonia or ammonia water with a concentration of 30-50% is transported between different places through tank trucks or sealed and corrosion-resistant transportation pipelines. After arriving at the destination, the ammonia enters the hydrogen production unit of the hydrogen generation station. For example, through an ammonia decomposition reactor containing a ruthenium catalyst, when the heating device is heated to 700 ° C, nitrogen and hydrogen are decomposed, and the obtained mixed gas passes through the gas separation chamber, and after the nitrogen adsorption device is separated, the purity higher than 90% can be obtained. The hydrogen gas the...

Abstract

An ammonia-transporting method for hydrogen uses an ammonia production method to transform hydrogen into liquid ammonia or ammonia water, and the liquid ammonia or ammonia water is transported from production places to users; before arriving at end users, the liquid ammonia or ammonia water are transformed into hydrogen again. The transporting method has the advantages of high transporting efficiency, little energy consumption and safe and economical property.

Description

technical field [0001] The invention belongs to the fields of energy power engineering and chemical engineering, and relates to a method for transporting hydrogen energy in a hydrogen economy. Background technique [0002] In order to get rid of excessive dependence on oil and seek diversification of energy sources, a hydrogen energy economy is about to emerge. The advantage of developing a hydrogen economy is that it can use a large amount of domestic resources, including coal, natural gas, and nuclear energy, for production, and does not need to rely on imports like oil. [0003] But hydrogen does not exist alone, it must be separated from other substances, and the large cost of separating hydrogen is one of the biggest problems of the hydrogen economy; another challenge in developing a hydrogen economy is safety issues, because hydrogen is colorless It is odorless, and its flame is invisible to the naked eye; secondly, the storage and transportation of hydrogen are the bi...
