Research progress in synergistic catalytic elimination of multiple pollutants in flue gas of coal combustion coupled with renewable fuels
Aiming at the problems of synergistic catalytic elimination of multiple pollutants(NO,Hg0,VOC,etc.)in the flue gas of coal combustion coupled with renewable fuels under the background of"dual carbon",we summarized the single component and multi pollutant synergistic catalytic elimination mechanism,interaction mechanism and catalyst design in this work.The mechanism of synergistic catalytic elimination of multiple pollutant is similar to that of single pollutant removal,but the performance of synergistic elimination is affected by interaction of pollutants and flue gas composition.The active components,heterogeneous reaction processes,and monolithic catalyst were reviewed.Finally,the prospect of synergistic catalytic elimination of multiple pollutants in flue gas of coal combustion coupled with renewable fuels is proposed that includes the catalyst optimization at the molecular and mesoscopic levels,high stability dispersion of active components,breaking the adsorption mode,design of anti-poisoning catalyst and systematic research in practical application.
