The fractal concept, created by Mandelbrot, has important consequences for the development of physical chemistry. Starting from the idea of the non-integer Hausdorff dimension fractal mathematics is a powerful tool for the description of irregular st

Influence of molecular shape on probing mass transfer resistances on zeolites

Autor: Rudiger Seidel, Harry Pfeifer, Frank Stallmach, Jörg Kärger, Martin Bülow, Herbert Spindler, Peter Struve, Roland Entner

Publikováno v: AIChE Journal. 36:1500-1504

Mass transfer resistances in zeolite NaCaA after different hydrothermal pretreatment are probed by NMR tracer desorption studies with the short-chain-length hydrocarbons from methane to n-butane and with xenon. In all cases, the measurements lead to

129Xe n.m.r. self-diffusion measurements — a novel method to probe diffusional barriers on the external surface of zeolite crystallites

Autor: Jörg Kärger, Frank Stallmach, Herbert Spindler, Harry Pfeifer

Publikováno v: Zeolites. 10:288-292

129 Xe n.m.r. pulsed-field gradient measurements have been carried out to probe the surface permeability of zeolites NaX, NaCaA, and ZSM-5. Although for zeolite NaX the passage through the external surface of the crystallite is found to be of minor i
