Integration of a 10 kWth RESC prototype system in a consisting biogas plant
The focus of this PhD work lies on the on-site production of high purity hydrogen out of biogas using the Reformer Steam Iron Cycle process (RESC). The main goal is the implementation of a 10 kWth prototype system into a consisting biogas plant. To reach the highest system efficiency, different integration scenarios have to be defined using simulation software. In addition, the needed process equipment has to be designed for the before defined scenarios. A further key aspect is the investigation of the influence of biogas impurities on the reactivity of catalysts and the used oxygen carrier material, which is analyzed in preliminary tests using a special designed test reactor system.
The experimental results are validated with process simulations and can be used for the design of a biogas pretreatment step to isolate significant components. Finally, a plant cost estimation of the defined scenarios should give information about the profitability of on-site hydrogen production out of biogas by chemical looping.
