Novel technologies of VOC decontamination in fixed, moving and fluidized catalyst‐adsorbent beds

Abstract

Abstract Some findings are reported on theoretical and experimental research studies of mechanical, structural, physical and chemical properties, micro‐and macrokinetic adsorptive, catalytic and regenerative characteristics of heterogeneous alumina catalyst‐adsorbents used for decontamination of individual volatile organic compounds (VOC) and their multicomponent mixtures. Data on fluid dynamics, heat and mass transfer in fixed, gravity‐moving and fluidized beds in novel energy‐saving (i) adsorptive, (ii) adsorptive‐catalytic, (iii) thermocatalytic with a quasistationary fluidized and (iiii) with a fixed catalyst beds and deep intercyclic heat recovery of purification systems are obtained and discussed. Correlations are suggested to calculate a number of investigated parameters, and the schematics and operating principles of these technologies are described.
