Process intensification in reverse flow reactors to boost various industrial applications: A review

Abstract

Reverse flow reactors are notable for their dynamic operation under unsteady state conditions, the minimization of energy use, and reduction of harmful greenhouse emissions. The main advantages offered by reverse flow reactors over conventional fixed bed reactors include enhanced reaction rates and reduced waste due to superior mixing and more efficient heat transfer. Sophisticated application of key principles of process intensification has facilitated the use of reverse flow reactors in numerous industrial applications including the oxidation of volatile organic compounds emissions, sulfuric acid production, reduction of NOx emissions from nitric acid production, steam-methane reforming for hydrogen production, and partial oxidation of methane for syngas production. This paper explores the potential of reverse flow reactors to promote sustainable chemical manufacturing processes with a reduced environmental impact across numerous industrial applications.
