Реферат:
The catalytic performance of supported Ru catalysts has been studied in the reactions of wet oxidation of acetonitrile, N,N-dimethyl formamide and carbamide at T=433–533 K and P=2.0–4.6 MPa, and wet oxidation of real sewage from an alcohol plant (so-called Luther water) at T=403–473 K and P=1.5–3.6 MPa. The Luther water contained a mixture of low-boiling (C1–C5) aldehydes and alcohols. The experiments were carried out in a perfectly mixed batch autoclave reactor. The conversion of alcohols and aldehydes contained in the Luther water and selectivity of the process towards CO2 and water as well as the selectivity of the oxidation of acetonitrile, N,N-dimethyl formamide and carbamide towards CO2, N2 and water were determined at various temperatures and reaction times. Ru (4.8 wt.%)/graphite-like carbon was effective in the oxidation of Luther water (ΔTOC=97.5% at T=423 K for 1 h), carbamide (XCO(NH2)2=100%, SCO(NH2)2→CO2=100%, SCO(NH2)2→N2=71% at 473 K, 2 h) and acetonitrile (XCH3CN=100%, SCH3CN→CO2=100%, SCH3CN→N2=75% at 493 K, 1 h). Ru/active carbon/γ-Al2O3 was effective in the oxidation of N,N-dimethyl formamide (XHCON(CH3)2=100%, SHCON(CH3)2→CO2=61%, SHCON(CH3)2→N2=100% at 493 K).
