An in situ thermal desorption (ISTD) soil remediation system may be used to remove or reduce contamination within soil. Heat may be transferred to the soil from resistively heated, bare metal heater elements. The heater elements may be placed directly within the soil. Alternately, the heater element ...

Eileen M Diakun, Christopher T Wright: Bleach activation. Interox Chemicals, Larson and Taylor, March 7, 1989: US04810410 (110 worldwide citation)

It is desired to enhance the ability of hydrogen peroxide and persalts at wash temperatures of around 30.degree. to 70.degree. C., in order to use less energy and to minimize damage to various fabric finishes. It has been proposed in the past to use transition metal compounds, including cobaltous co ...

Christopher J Nagel: Method and system for controlling chemical reaction in a molten bath. Molten Metal Technology, Hamilton Brook Smith & Reynolds, March 2, 1993: US05191154 (95 worldwide citation)

A method and a system is disclosed for controlling chemical reaction of a feed. The feed is directed into a reactor containing a molten bath to at least partially chemically react the feed to form an intermediate component. A portion of the intermediate component is combined with an off-gas which is ...
