...Alexander Raymond; Srinivas Garimella Adsorption heat pumps and chillers (ADHPCs) can utilize solar or waste heat to provide space conditioning, process heating or cooling, or energy storage. In these devices, intraparticle diffusion is shown to present a significant mass transfer resistance...

... desorption and addition pathways. Comparison of cases that were run with and without thermodiffusion shows that the ratio of hydrocarbon adsorption to desorption declines by 16% for deposition at 1198 K with 20% methane. The result of this new equilibrium condition is that the surface CH 3...

...Minh Do-Quang; Gustav Amberg; Claes-Ove Pettersson This paper presents a comprehensive three-dimensional, time-dependent model for simulating the adsorption kinetics and the redistribution of surfactants at the surface and in the bulk of a weld pool. A physicochemical approach that was included...

... for adsorptive separation of liquid mixtures in chemical industries. A novel moving-port system is proposed to achieve simulated moving-bed operation in a fixed bed. We have carried out studies to evaluate the relative performance of the fixed and the simulated moving-bed heat regenerators. We have examined...
