| description | In order to solve the problem of low carbon conversion rate in the conventional in-situ carbon capture gasification process based on fixed bed or bubbling fluidized bed reactor, in this paper, a transport bed is applied as the reactor of the in-situ carbon capture gasification for hydrogen production.The dynamic model of the reactor combining hydrodynamic models and reaction kinetic models is built to investigate the operation feasibility and influence of key parameters, such as steam to carbon ratio, operation temperature and pressure, on reactor performance.The study concludes the operational conditions of the reactor when it has operational feasibility.Meanwhile, results show that, take a small test transport equipment as basis, the reactor is recommend to operate at pressure of 900 kPa, temperature of 800 ℃ and steam to carbon ratio of 2.Under this condition, the H<sub>2</sub> composition in the dry gas could reach 82 % together with the carbon conversion of 60 %.The results confirmed the feasibility of the transport bed as the in-situ carbon capture gasification reactor and its advantage in improving the in-situ carbon capture gasification performance, determined the ranges of reactor operation conditions, which provide a reference for the development of hydrogen production technology by in-situ carbon capture gasification. |
