In addition, experiments showed that lowering the water concentration using pure water as the solvent also increased the phenol conversion. The results suggest that dilution with helium (and perhaps other inert gases) may be a new way to control SCWO reaction rates....
Here, we report on the direct probing of a photochemical reaction occurring at the air–water interface, using ultrafast phase-sensitive interface-selective nonlinear vibrational spectroscopy. The femtosecond time-resolved data obtained clearly show that the photoionization reaction of phenol proceeds 104 ...
It was found that H_2 and H_2O_2 was produced during the streamer discharge in water with production rates of 0.021 mg/min and 0.55 mg/min, respectively. Increasing the discharge duration resulted in increased H_2O_2 concentration, phenol degradation rate, water conductivit...
A reaction network model for phenol oxidation in supercritical water Dilute aqueous solutions of phenol were oxidized in a flow reactor at 420, 440, 460 and 480°C at 250 atm. Phenol disappearance kinetics followed the trend... S Gopalan,PE Savage - 《Aiche Journal》 被引量: 656发表: 1995...
The results obtained from enzyme-immobilized membrane reactor showed that the reaction rate was diffusion controlled. The stability of the immobilized enzyme was better than that of the free enzyme in solution and the immobilized enzyme kept 70% of its initial activity for approximately 100 h. The...
For example, benzene can be converted into phenol with a yield of at least 30-40%, and a selectivity on the basis of benzene of at least 95-97%. The selectivity for this reaction based on NO is at least 90-95%. Therefore, no substantial NO decomposition or consumption for complete ...
Polyacrylamide and water-soluble phenol-formaldehyde resin can produce crosslinking reaction to generate the movable gel, which can be used in deep profile control to enhance oil recovery. In this paper, the preparation process of water-soluble phenol-formaldehyde resin crosslinking agent (polyhydroxyme...
The effects of aqueous solution pH, reaction temperature, amounts of catalyst and H2O2 used, reaction time, stirring speed and Si/Al ratio on the degradation rate of phenol in waste water with high concentration were investigated, respectively. The results show that the degradation rate of phenol...
Degradation of phenol in the presence of a background NaCl electrolyte produces chlorinated phenols as reaction intermediates, which are subsequently oxidized ... H Park,CD Vecitis,MR Hoffmann - 《Journal of Physical Chemistry A》 被引量: 96发表: 2008年 Photocatalytic interconversion of nitrogen-cont...
