Scale‐up of fixed‐bed chemical looping combustion

摘要

Fixed‐bed chemical looping combustion is currently being studied experimentally with theoptimization of systems up to 1 kW. One of the key advantages for using the fixed‐bed configurationover fluidized‐beds is the flexibility in operating parameters that allows for application of CLC not onlyto power production, but also to niche applications, such as the decoupled production of heat and CO2for the greenhouse industry. Another advantage is the modularity of the systems that greatlysimplifies scale‐up once the optimal single reactor design is realized. This is currently being studied byoptimizing the production of pure CO_2 while minimizing the pressure drop over the reactor. Withresults for three different sizes of reactors, optimal packing and operating conditions can be predictedfor increasingly larger systems while being tailored to the specific application.
