  • Process of forming compounds using reverse micelle or reverse microemulsion systems
    Patent number: 5770172
    Abstract: The present invention is directed to a process for producing a nanometer-sized metal compound. The process comprises forming a reverse micelle or reverse microemulsion system comprising a polar fluid in a non-polar or low-polarity fluid. A first reactant comprising a multi-component, water-soluble metal compound is introduced into the polar fluid in a non-polar or low-polarity fluid. This first reactant can be introduced into the reverse micelle or reverse microemulsion system during formation thereof or subsequent to the formation of the reverse micelle or microemulsion system. The water-soluble metal compound is then reacted in the reverse micelle or reverse microemulsion system to form the nanometer-sized metal compound. The nanometer-sized metal compound is then precipitated from the reverse micelle or reverse microemulsion system.

  • Catalyst material and method of making
    Patent number: 5652192
    Abstract: The material of the present invention is a mixture of catalytically active material and carrier materials, which may be catalytically active themselves. Hence, the material of the present invention provides a catalyst particle that has catalytically active material throughout its bulk volume as well as on its surface. The presence of the catalytically active material throughout the bulk volume is achieved by chemical combination of catalytically active materials with carrier materials prior to or simultaneously with crystallite formation.

  • Method for solubilization of low-rank coal using low molecular weight cell-free filtrates derived from cultures of coriolus versicolor
    Patent number: 5084160
    Abstract: A method is provided for isolating a less than 5,000 dalton molecular weight extracellular product from Coriolus versicolor. The extracellular product is useful for biosolubilizing low-rank coals to form water-soluble products.
