AbstractElectrothermal Regeneration of Adsorbers ‐ Survey of Research and DevelopmentThis article surveys the current state of the art in research and development in the area of electrothermal processes for the regeneration of spent adsorbers. In addition to processes based on the induction of electrical current in adsorber beds the paper considers processes in which the required desorption energy is supplied to the system by microwave

摘要:

AbstractElectrical Double Layers: Electrostatics and Electrodynamics Dispersions of solid particles in aqueous solutions almost invariably bear a surface charge which is compensated by an opposite charge in the solution. An electrical double layer is formed. The surface charge can sometimes be determined by titration. In practice, the electrokinetic potential or zeta potential is usually measured. This potential is a characteristic quantity for stability, rheology, sedimentation, etc., of disperse systems. This paper addresses the question of the relation of the electrokinetic potential to the static double layer parameters. To this end the author provides a detailed account of electrokinetic shear processes. In addition, new results obtained with the aid of molecular dynamics are also presented.

摘要:

AbstractPredictive Accuracy of Design Methods for the Relief Cross‐Sections for Runaway Reactions On the basis of calculations performed on the results of experiments conducted in reactors with volumes up to 10 m3for so‐called vapour‐pressure producing (runaway) reaction systems, it is found that all simplified or steadystate methods regularly afford overdimensioned relief cross‐sections. As a consequence, unnecessarily large mass flows leave the reactor to enter the containment system. A balanced design of both plants components is possible only with the aid of transient methods. In the case of gas generating reactions simplified methods also lead to excessively large pressure relief cross‐sections. Design with the aid of a transient method for such a reaction system is rendered difficult by the fact that a conservative submodel cannot be used a priori for description of the expansion behaviour. A parametric study is then
