The CASOH process under development in the C4U project is based on a high-temperature solid looping system. This process uses packed-bed technology combined with pressure and temperature swing stages. In the CASOH reaction stage, the Cu-based material catalyzes the water-gas-shift (WGS) reaction of the CO contained in the BFG with steam, whereas the CaO-based material reacts with the CO2 present in the inlet BFG and the CO2 generated in the WGS reaction. As a result, a decarbonized fuel gas concentrated in H2 and N2 is obtained in this stage. The remaining two reaction stages (“oxidation” and “regeneration”) are designed to produce, in concentrated form, the CO2 stored as CaCO3 during the CASOH stage. 

The present document describes all the necessary pre-test work to ensure that the pilot plant can operate as planned, following standard testing and approval regime of prototype to comply with existing permits for operation of pilots in the GasLab site of AMA. This implies the acceptance by AMA and CSIC (beneficiaries in charge of the commissioning of all pilot components) of all pilot elements and all the works carried out by service providers participating in the construction of the pilot plant. The finalization of all the commissioning works presented in this deliverable marks the beginning of the experimental works towards long-term tests at TRL7.
