METHOD OF PREPARING NICKEL-BASED METAL FIBER CATALYST Russian patent published in 2003 - IPC

FIELD: all-purpose catalysts. SUBSTANCE: catalysts designed for chemical, food, and varnish-and-paint industries, which can be employed both in liquid-phase and gas-phase catalytic processes, is prepared by melting alloy and immersing therein rotating cooled disc for extraction of melt in the form of edges of solidified metal fibers, said alloy is preliminarily supplemented by aluminum in amounts 0.5 to 20 wt % and said fibers thus obtained are subjected to leaching to a depth of 0.01 to 0.1 equivalent diameters fiber. EFFECT: increased specific activity of catalyst. 1 tbl, 5 ex
