CATALYST FOR PURIFICATION OF AROMATIC HYDROCARBONS FROM UNSATURATED COMPOUNDS AND THIOPHENES Russian patent published in 1995 - IPC

Abstract SU 1504864 A1

FIELD: catalytic chemistry. SUBSTANCE: catalyst has, wt.-% molybdenum oxide 5-15; cobalt oxide 2-6; sodium oxide 0.03-0.8, and aluminoboron carrier (at mass ratio B2O3:Al2O3 = 0,033-0,214) the rest. Selectivity of new catalyst by 150 times more as compared with known one, and its high stability is retained for 240 h (content of thiophene in hydrogenisate is 0.3-0.5 ppm, naphthene hydrocarbons is 0.002-0.003 wt.-% bromine index is 0.002-0.003 g Br2/100 cm8). EFFECT: increased stability of catalyst, retained high selectivity. 1 tbl
