The paper presents the feasibility studies on wet air oxidation studies being carried out using the dissolved resin feed having COD value upto 50000 ppm on pilot scale set-up under a pressure upto 20 bars for various durations. This paper also presents comparison of various industrial practices being adopted for treatment of spent resin.

The chemical stability of pentaerythritol tetranitrate (PETN) when placed in physical contact with metal oxides is investigated. In this study, PETN was placed on the surfaces of a range of microcrystalline metal oxides including MnO in coverages of 1-3.5 monolayers by a wet impregnation technique. Samples were then placed in a controlled temperature environment at 50 C and checked periodically for the presence of decomposition products using liquid chromatography. PETN proved to be inert over all of the oxides except MoO 3 , which showed the relatively rapid evolution of a brown gas over a period of 48 h. Analysis of the evolved gas indicated that it is primarily NO 2 along with N 2 O 4 , N 2 O, and CO 2 .

Ordered mesoporous Fe 2 O 3 was synthesized using cetyltrimethylammonium chloride (CTAC) and polyethylene glycol octadecyl ether (Brij 76) surfactant templates. The gel time was monitored as a function of the concentration ratio of precursor to the surfactant. ...
