. . . "Diffusion coefficients and other transport characteristics are indispensable for application of chemical reaction engineering approaches to chemical/biochemical processes. The project will developed and verified a new method for determination of diffusion coefficients and other transport characteristics of industrial porous solids with nonstandard shapes(which guarantee high outer surface to volume ration). The chromatographic method in SPSC arrangement will be aplied. Necessary software, which will fit experimental column responses in time domain and use the convolution integral, will be developed. To decrease the number of fitted parameters the axial dispersion parameter (Peclet number) will be obtained independently from responses of SPSC packed with porous pellets with pores blocked by a suitable liquid (nonporous packing). The obtained diffusion coeficients and other transport characteristics will be compared with characteristics from standard textural analyses."@en . . . .
