BINDING FOR CARBONACEOUS MATERIAL PREPARING AND ARTICLES MADE OF THEIRS Russian patent published in 1994 - IPC

Abstract RU 2008297 C1

FIELD: carbonaceous materials. SUBSTANCE: binding on coal pitch-base has additionally products obtained by treatment of resin after petroleum products pyrolysis and/or distilled cracking-residue with air at 260-350 C. Exploiting properties of binding used for preparing of carbonaceous mass (softening point, ash content, coking capacity) are comparable with that of binding consisting of coal pitch, but has decreased content of benzo(a)pyrene (strong cancerogenic agent) in sublimates (by 4-10-times). EFFECT: improved ecology. 3 cl, 1 dwg, 4 tbl
