  • Patent number: 7901644
    Abstract: Processes are described for the extraction and recovery of alkali metal from the char that results from catalytic gasification of a carbonaceous material. Among other steps, the processes of the invention include a hydrothermal leaching step in which a slurry of insoluble particulate comprising insoluble alkali metal compounds is treated with carbon dioxide and steam at elevated temperatures and pressures to effect the conversion of insoluble alkali metal compounds to soluble alkali metal compounds. Further, processes are described for the catalytic gasification of a carbonaceous material where a substantial portion of alkali metal is extracted and recovered from the char that results from the catalytic gasification process.

  • Patent number: 5322600
    Abstract: The present invention provides an improved method and apparatus for removing dissolved selenium from a wastewater solution. The apparatus treats heated selenium containing solution in a single, flow-through operation by employing both the anode chamber and cathode chamber of an electrolytic cell and a series of sub-micron filters. In operation, the present invention has proven to be very effective in treating selenium containing solution to meet or better the government toxicity characteristic specifications of .ltoreq.1 ppm.

  • Patent number: 5009868
    Abstract: The present invention discloses a process for rejuvenation of strip acid employed in the reclamation of expended lead-acid battery acid through extraction and filtration for removing metallic impurities from the battery acid. In the process of removing impurities from battery acid through extraction, the extractant becomes loaded with impurities and loses its effectiveness. Extractant may be regenerated by contacting it with an strip acid. In the present invention, a reduction process is employed to regenerate the strip acid so that it may be used repeatedly. By recycling the extractant and the strip acid in the present invention, the present process further increases the effectiveness of battery acid regeneration--producing a reclaimed battery acid fluid which performs very well in new batteries and substantially reducing by-product waste in the regeneration of the battery acid.
