PP-III-53The aim of this work is to study the catalytic properties of the nitrogen-containing carbonmaterials in the model and red-ox reactions of the enviromental catalysis.The active carbons (AC) SKN, KAU and the active carbon cloth (ACC) were studied.Nitrogen-containing activated carbon SKN was produced by step pyrolysis of a vinilpyridinedivinilbenzenecopolymer at 350-900 o C in an inert atmosphere, and further steam activationat 850 o C. For preparation of AC-N it was used AC KAU prepared from peach and apricotstones. Initial carbon KAU and ACC were obtained by a procedure, specially designed by theauthors: impregnation with water solution of melamine in various relations melamine:carbon,then subjected to heat treatment at 800 o C in a stream of argon. As a result the KAU-N fndACC-N with content of nitrogen 1 - 6 % on mass were obtained.The introduction of nitrogen in a matrix of AC-N results in essential increase of activityof catalysts. Dependence of catalytic activity on the contents of nitrogen on the carrier hasextreme character. The carbon samples with the 3 mas. % of nitrogen in structure are mostactive.572
