The theme of coupling problems for adsorption, absorption and thermochemical transport in porous media is very important for engineering applications. Based on the submissions to the mini-symposium 22 of InterPore 2020, this special issue used this opportunity to evaluate some of these papers, and also invite some other scholars to submit their latest original research findings which are either advances in the state of the art of numerical models, molecular studies or experimental studies for new contributions. All the submissions developed existing models or methods and showed the critical engineering problems in 'Adsorption, Absorption and Thermochemical Transport Processes in Complex Porous Structures' to be presented in the journal Transport in Porous Media.
Keywords Porous media • Adsorption • Absorption • Thermochemical transport • Heat and mass transferPorous media refer to a special kind of solid materials with pore spaces distributed continuously on the macroscopic level (randomly on the microscopic level) and have a very wide range of applications in all walks of life. Therefore, this special issue, involving the term 'Complex Porous Structures,' paid a special attention to various aspects of fluid dynamic, heat and mass transfer as well as adsorption/absorption generally. Adsorption, absorption and the related thermochemical transport processes porous media are very important * H. J. Xu
