Abstract

A mathematical model (CRAS) has been developed to evaluate the behavior of trivalent chromium (Cr(III)) in the activated-sludge process. The validity of the model was tested by comparing its prediction with experimental data. Laboratory-scale continuous-flow activated-sludge reactors receiving a continuous Cr(III) dosage provided the data. The independent experimental parameters were sludge age (theta(sub x)) and pH: theta(sub x) = 5, 10, and 15 days; pH = 6, 7, and 8. Comparison of the experimental results with the predictions revealed that: (1) More Cr(III) was intracellularly transported into the solid phase than Cr(III) adsorbed on activated sludge; and (2) the solid-bound Cr(III) per unit weight of suspended solids in the effluent was considerably greater and more varied than that in the mixed liquor. By incorporating these two findings, the CRAS model was found capable of predicting quantitatively the percentage removal of Cr(III) (the average relative error was 4.5%) and the total Cr(III) concentration in the mixed liquor (14.9%) as a function of pH and theta(sub x).

Abstract

The hydrolysis kinetics of acetamide in supercritical water (SCW) was faster than acetamide oxidation kinetics. This difference between hydrolysis and oxidation kinetics supports the use of SCW as an active reagent. Additionally, the use of hydrogen peroxide as an oxidant proved ineffective, and this result supports the use of oxidants that are just above stoichiometric demand.

Abstract

Sodium and borate ions are separated in supercritical water by addition of dissolved CO.sub.2 to cause precipitation of carbonates and the formation of boric acid. Carbonates and boric acid are then recovered as separate products.

Abstract

A method of producing an off-gas with a selected CO/H.sub.2 ratio of from about 0.1 to about 8 and a CO/CO.sub.2 ratio of at least about 0.1 by hydrothermal processing is provided. The method comprises the step of contacting a reactant capable of producing CO and H.sub.2 under hydrothermal conditions at a temperature of at least about 374.degree. C. and a pressure of at least about 22.1 MPa in the presence of water and with an amount of an additive effective to produce the selected CO/H.sub.2 ratio. The contacting is for a time sufficient to produce off-gas having the selected CO/H.sub.2 ratio and having a CO/CO.sub.2 ratio of at least about 0.1. Presence of the additive may enhance or may reduce the ratio of carbon monoxide to hydrogen in the off-gas. The additive may be an acid, a base, a salt, an oxide, or an oxidant. The off-gas having a selected CO/H.sub.2 ratio may be used for synthesis of organic compounds.

Abstract

A system for effective utilization of reaction heat and in situ separation of solid and gaseous products in wet oxidation of waste and wastewater. This invention does not require special preheaters for preheating feed streams, therefore reducing the possibility of scale and char formation in the heat exchange zone. The cold feed stream is introduced into the reactor with part of the effluent which has been recycled through a high temperature pumping means to form a hot, near critical oxidant-containing mixture. The cold feed is directly heated up by the oxidant-containing mixture. The reaction mixture is separated by in situ crossflow filtration elements, including sintered material. Catalyzed reactions and sintered material gas separation are also described.
