CATALYTIC AGENT FOR PREPARING OF AROMATIC COMPOUNDS Russian patent published in 1994 - IPC

FIELD: petrochemistry. SUBSTANCE: catalytic agent has platinum or palladium lying in the range 0.3 - 1.0 percent by weight applied on catalytically active substance which in its noncalcined condition corresponds to formula 1 . Me (II) = copper, magnesium, zinc or their mixture. Me (III) - aluminium, chromium or iron; x = 1 - 20, y = 2, with x and y corresponding to the ratio x/y greater or equal to 0.5. The X-ray diffraction (d0003) is roughly more than 7.4Me(II)_xMe(III)_y(CO₅)(OH)_2x+3y-2·(0.5-20)H₂O. The catalytically active substance is subjected to preferential preliminary calcination at the temperature ranging from 400 to 7000 C. The catalytic agent is marked by up to 88.5 percent selectivity of forming aromatic compounds. EFFECT: higher quality, increased range of application. 3 cl, 4 tbl
