Process simulation and techno-economic assessment of SER steam gasification for hydrogen production

摘要

In the SER (sorption enhanced reforming) gasification process a nitrogen-free, high calorific product gas can be produced. In addition, due to low gasification temperatures of 600 750 degrees C and the use of limestone as bed material, in-situ CO2 capture is possible, leading to a hydrogen-rich and carbon-lean product gas. In this paper, results from a bubbling fluidised bed gasification model are compared to results of process demonstration tests in a 200 kW(th) pilot plant.
