DOIAbstract
A hydrogen purification device has been designed and implemented at a prototype scale. The device operation is based on the use of a hydride forming material distributed in two reaction beds, which work in opposition. Under the proposed design, one of the reactors receives the incoming gas, absorbing the hydrogen in it, while the other one desorbs pure hydrogen after a brief venting stage in which contaminants are eliminated. Thus, a continuous flow is processed. The reactors are thermally coupled in order to use the heat of reaction and save energy, working at room temperature without the need of additional heat sources or sinks. The reaction's behavior can be described by a lumped computational model. The model is validated against measur...
