Solid catalysts for wet oxidation of nitrogen-containing organic compounds

Ruthenium nanoparticles supported on nitrogen-doped carbon nanofibers for the catalytic wet air oxidation of phenol

“…Meantime, the reaction time does not influence significantly the nitrogen content in N-CNFs. For comparison, in this work we used graphite-like mesoporous carbon Sibunit ® , which proved to be a good support for CWAO catalysts [28,31].…”

Ruthenium catalysts supported on high-surface-area zirconia for the catalytic wet oxidation of N,N-dimethyl formamide

“…However, there is not so much attention paid to remove the toxicant by CWAO. Only Dobrynkin et al [8] and Batygina et al [3] investigated the activities of supported Ru catalysts in the CWAO of DMF; and Ru active carbon ␥-Al 2 O 3 was found to be very effective with 100% conversion and 100% selective to N 2 at 493 K [3].…”

Catalysts Ru–CeO2/Sibunit for catalytic wet air oxidation of aniline and phenol

“…Cylinder reactors are made of steel 12X18H10T. The diagram of the low volume reactor is described elsewhere [6], the mixing has been provided by variations of frequency and amplitude of reactor vibrations. The experimental set-up consists of reactor, systems for oxygen (air) supply and pressure regulation, and temperature control.…”

“…Then, 100 ml of organic/ water solution of an adjusted concentration was loaded, reactor heated to a certain temperature, pressure regulated oxygen supply was performed and shaking was started (this moment is taken as s ¼ 0). To intensify mass exchange in a liquid-gas-solid system all catalysts were tested at the frequency of 4-6 Hz and amplitude of 50 mm [6]. All tests were done at the same oxygen pressure, and liquid phase was periodically taken (ca.…”

“…The formation of toxic wastes, in particular those formed on reburning of halogen-and nitrogen-containing compounds, to be obviated by using CWAO for wasters purification [1][2][3][4][5]. However, the further technological progress requires commercial catalysts that meet special requirements [6], such as high stability and activity under CWAO conditions. Currently, these catalysts are of vital importance for such processes as cleaning of petrochemical, by-product cocking, cellulose, textile (in particular, dying plants) wastewater, for organic synthesis, food industry etc.…”
