The nature of permeability anisotropy and catalytic activity

Dry reforming of methane on porous membrane catalytic systems

“…As follows from Figs 7 and 8, with an increase in the temperature of the process, the rates of СО 2 and methane transformation are closer on the system Pd-Mn (5) than those on the La-Ce containing system (4).…”

“…Titanium n butylate was used along with heterometallic ac etate complexes Pd(μ OOCMe) 4 Co(OH 2 ) (1), Pd(μ OOCMe) 4 Zn(OH 2 ) (2), and Pd(μ OOCMe) 4 Mn(OH 2 ) (3) to form the Pd-M containing catalytic systems in the internal volume of the ceramic membrane.…”

“…1 The development of the process of com bined methane and carbon dioxide reforming is of practi cal interest for the rational use of carbon from industrial flue gases and biogas. High thermodynamic stability of СН 4 and СО 2 molecules impedes this problem. Neverthe less, both these components of biogas belong to promising non petroleum resources for the production of important carbon containing products and hydrogen.…”

“…Cata lytic setups based on microreactors have small sizes, which simplifies a designing task and thus makes it possible to replicate rather than scale up the membrane reactor unit. 3, 4 Channels of porous membranes modified by highly dis persed nanosized catalytic systems can serve as microre actors. The number of channels with an effective cross section of 3 μm is up to 10 7 per square centimeter of the membrane.…”

Permeability of model porous medium formed by random discs

“…The understanding of filtration processes is necessary in urban construction, in particular when using various methods of flood protection [1], for increasing the rate of catalytic reactions inside the porous membranes in chemistry technologies [2], for improving the performance of filtration units and for increasing the oil or gas production in oil and gas technologies [3]. Therefore, experimental methods determining the free volume in materials with internal structure are developed [4].…”
