Intensification of Chemical Looping Processes by Catalyst Assistance and Combination

Abstract

Chemical looping can be considered a technology platform, which refers to one common basic concept that can be used for various applications. Compared with a traditional catalytic process, the chemical looping concept allows fuels’ conversion and products’ separation without extra processes. In addition, the chemical looping technology has another major advantage: combinability, which enables the integration of different reactions into one process, leading to intensification. This review collects various important state-of-the-art examples, such as integration of chemical looping and catalytic processes. Hereby, we demonstrate that chemical looping can in principle be implemented for any catalytic reaction or at least assist in existing processes, provided that the targeted functional group is transferrable by means of suitable carriers.

Catalytic Dehydrogenation of Ethane: A Mini Review of Recent Advances and Perspective of Chemical Looping Technology

“…It should be noted that by-product hydrogen H 2 limits the conversion of ethane, whereas the selective oxidation of ethane occurs the formation of H 2 O leading to much higher single pass yield of ethylene. The increase in the yield of ethylene leads to a lowered molar flow rate of non-condensable gaseous products from the reaction, which makes it a much more energy efficient process [79]. In cyclic oxidation schemes, the redox catalyst is in a state of dynamic change between the ethane ODH and air regeneration stages, due to the concomitant consumption and regeneration of crystal lattice oxygen.…”
