Modeling of Reverse-Flow Reactor for VOC Incineration with Account of Reversible Adsorption: The Way to Minimize the Negative Influence of Desorption Phenomena

摘要

The paper discusses the influence of adsorption/desorption phenomena on thenpurification performance of the reverse-flow catalytic incinerator for abatement ofnvolatile organic compounds (VOC). It is shown that the reversible adsorption ofnVOC at the catalyst surface may occur at the catalyst bed inlet in the end of the cycle,nfollowed by desorption into outlet gases after flow reversal leading to decreasenof the process purification efficiency. The mathematical modelling results showednthat inert material beds in combination with proposed process control strategy arenneeded to avoid negative influence of adsorption effects.
