FLOW MODULE FOR MEMBRANE CATALYSIS AND GAS SEPARATION AND METHOD OF ITS FABRICATION Russian patent published in 2012 - IPC B01D69/02 B82B3/00 

FIELD: process engineering.

SUBSTANCE: invention may be used for gas mix separation and fabrication of flow membrane catalysts in ultra- and microfiltration. Asymmetric flow module for membrane catalysis and/or gas separation at up to 1000°C comprises macroporous ceramic substrate and membrane. Said membrane is made by anodic oxidation of aluminium secured on substrate by thermosetting and has through pores perpendicular to membrane surface. Said pores feature diameter varying from 5 nm to 500 nm, preset architecture and dispersion of their diameters in aluminium oxide layer not exceeding 15%. Said module may be reclaimed in the case of organic substances by annealing in oxidative atmosphere. Preset architecture of pores is ensured by anodic oxidation carried out in several steps at different strains. Pore walls may be modified by applying metal catalytically active particles.

EFFECT: sufficient mechanical strength at pressure variations of up to 10 bar and stability after annealing at over 800°.
