A supercritical oxidation process carried out in water is capable of oxidizing 'organics' in precious metal organic compositions such as heterogeneous (Pt/C) or homogeneous precious metal catalysts and producing a precious metal oxide with few by-products and low losses of precious metal.

Precious metal recovery from organics-precious metal compositions with supercritical water reactant

In a high pressure and high temperature reaction system suitable for oxidative waste treatment, particularly a reaction system for supercritical water oxidation (SCWO), a method is disclosed for injecting a first fluid of a first temperature at a first flow rate into a second fluid of a second temperature at a second flow rate, mixing the first and the second fluids within a mixing length (), and wherein the first and second temperatures and the first and second flow rates are selected such that a temperature of the mixed fluids downstream of said mixing length () is obtained, at which said first fluid being substantially non-corrosive.

High pressure and high temperature reaction system

A method for avoiding the precipitation of salts from a salt containing water stream prior to the stream reaching a supercritical water reactor is presented. The salt containing water stream is preferably kept at temperatures below supercritical conditions as the stream is transferred to the reactor. After the salt stream reaches the reactor the temperature of the salt stream is preferably raised to the appropriate temperature by mixing the salt stream, within the reactor, with a second stream that has been heated above the supercritical temperature of water. Alternatively, a method for preventing the clogging of the conduits upstream from the reactor may involve the mixing of two subcritical waste streams. One stream may include salts, the other preferably includes oxidizable material. The heat produced by the reaction of the oxidizable materials within the reactor preferably allows the mixture to remain at supercritical conditions for a time sufficient to oxidize substantially all of the oxidizable material.

A new process for the stabilization of bacampicillin hydrochloride against degradation by humidity characterized by the incorporation of between 3 to 9% by weight of straight-chain alkanes, alkenes, fatty acids, alcohols, and esters of fatty acids and alcohols with molecular weights between 144 and 350, which may be carried out in one step together with wetmassing for granulation.
