Diffusionvorrichtungen zur Erleichterung der Materialübertragung in Feststoff-Gasreaktionen

摘要

The diffusing elements are intended to facilitate the transfer of matter in solid-gas (endo- or exothermic) reactions between a reactive gas and a reactive composite material, and are embedded in the reactive composite material to facilitate the diffusion of the reactive gas, and are characterised in that, a) these diffusion elements are sections made of carbonaceous porous material, b) these elements exhibit a low pressure drop in the so-called "direction of travel" of the reactive gas, c) in the so-called "direction of diffusion", perpendicular to the said direction of travel, these elements exhibit a measured crushing strength of at least 1 MPa and a permeability of at least 10<-5> m<3>/m<2> s Pa.
