Kinetics of wet air oxidation of diethanolamine and morpholine

Kinetics of Wet Air Oxidation of Glyoxalic Acid and Oxalic Acid

“…Recently, Mishra et al (1994) have observed that during wet air oxidation of diethanolamine and morpholine, the rate of oxidation is significantly higher in a mixture of both when compared to individual rates. Therefore the applicability of such modeling is difficult to comprehend.…”

Studies in wet air oxidation of aqueous morpholine over Ru/TiO2 catalyst: an insight into the fate of the ‘N’ atom

“…The non-catalytic WAO of aqueous morpholine and diethanolamine was earlier reported by Mishra et al 15 In order to have less severe operating conditions for WAO, it was thought desirable to employ a catalytic process for morpholine mineralization. Qin and Aika 10 observed the exceptional ability of Ru to oxidize ammonia during WAO studies.…”

“…It has been observed that morpholine is resistant to biodegradation 14 . Non-catalytic WAO of morpholine has been reported by Mishra et al 15 In the present study attention has been focused on maximizing conversion of the -NH-group in the heterocyclic ring to N 2 during CWAO of morpholine. The efficient destruction of morpholine and chemical oxygen demand (COD) of the system is essential because in the presence of nitrites, morpholine can form carcinogenic nitroso compounds.…”

“…To make models more realistic and simple, the entire rate is expressed as the catalytic reaction rate. The homogeneous noncatalytic reaction 15 is not considered.…”

ACCELERATION OF THE WET OXIDATION REACTION OF PIPERAZINE BY HETEROGENEOUS Ru/TiO2CATALYST

“…It is thus obvious that a comprehensive study of the wet oxidation of PZ constitutes an important challenge. The non-catalytic wet oxidation of the heterocyclic amine morpholine (MOR) has been investigated earlier, e.g., by Mishra et al (1994). However, there exists no information in the literature on PZ oxidation.…”
