TEXTILE FIBROUS BULKED CATALYST Russian patent published in 1998 - IPC

FIELD: chemical, oil, light industries, in particular, materials used in catalytic processes, for instance, for cleaning sewage and gas outbursts from sulfides. SUBSTANCE: textile fibrous bulked catalyst is made in the form of fabric (for instance, rib knit fabric) having carrier layer made from single filaments and modified ion-containing complex threads of polyacrylonitrile filaments including one or two ions of metal of variable valence. Weight ratio of carrier layer single filaments and polyacrylonitrile filaments of textile fabric is 60.7-82.3%, linear density of polyacrylonitrile filaments is 32/2-32/4 tex, loop surface module is 3.17-3.35, total linear density of weft and warp threads is 156.3-211.7 tex. EFFECT: increased efficiency by intensified sulfide oxidation rate and wider operational capabilities. 1 tbl, 44 ex
