Overview of chemical looping technologies for process intensification: A perspective

Abstract

Chemical looping is a promising technology for clean and efficient conversion of fuel to electricity with integrated carbon dioxide capture, offering a potential for process intensification by eliminating the gas separation unit, leading to significant improvement on process efficiency and reduction on process complexity. In addition to power generation, chemical looping technology has also started to receive attention for the production of valuable chemicals, providing opportunities for process intensification with a potential increase in process efficiency and reduction in emissions. This perspective article provides an overview of different chemical looping processes that are used for both power generation and chemical production and discusses their potential for process intensification while providing an outlook for future research directions.
