The modularized system incorporates CO2 capture and utilization as a feedstock in an iron-titanium composite metal oxide based chemical looping system to enhance coal based chemical production.<\/p>\n<p>Simulations conducted in ASPEN Plus software suggest that adopting a cocurrent moving bed reducer reactor based modularization strategy can improve syngas yield by greater than 11% over a single chemical looping reducer reactor. Experiments conducted on a bench scale reducer reactor confirm the findings of the simulations. The modularization simulation was scaled up and incorporated into commercial sized methanol and acetic acid production plants.<\/p>\n<p>Chemical looping modularization demonstrates the ability to reduce coal consumption by 25% over a baseline coal gasification process, compared to 15% reduction if a single chemical looping reducer reactor is used instead of the modular strategy, for 10,000 ton per day methanol production. Integration into a commercial scale acetic acid plant shows conditions in which the process can operate as a CO2 neutral or negative system, where the process was consuming more CO2 than it produces. These results indicate the potential for significant feedstock reduction in large-scale coal to chemical processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This study quantifies the advantages of a chemical looping reducer reactor modularization strategy that leverages two or more reducer reactors operating in parallel to enhance syngas production beyond what is achievable by a single reducer reactor or conventional processes.
