摘要： Processes and systems for converting glycerol to propylene glycol are disclosed. The glycerol feed is diluted with propylene glycol as the primary solvent, rather than water which is typically used. The diluted glycerol feed is sent to a reactor where the glycerol is converted to propylene glycol (as well as other byproducts) in the presence of a catalyst. The propylene glycol-containing product from the reactor is recycled as a solvent for the glycerol feed.

摘要： Catalysts for replacing rhenium-containing multimetallic catalysts for the hydrogenolysis of organic compounds to desired polyols, including the conversion of glycerol to propylene glycol, are described. The catalysts are carried on carbon supports, as well as carbon supports impregnated with Zirconium Scandium (ZrSc), Zirconium Yttrium (ZrY), Titanium Scandium (TiSc), or Titanium Yttrium (TiY) to texture the carbon support and to create oxygen-ion vacancies that can be used during the desired reactions. Processes for the hydrogenolysis of organic compounds to desired polyols using the disclosed catalysts, including the conversion of glycerol to propylene glycol, are also described.

摘要： Continuous processing of wet biomass feedstock by catalytic hydrothermal gasification must address catalyst fouling and poisoning. One solution can involve heating the wet biomass with a heating unit to a temperature sufficient for organic constituents in the feedstock to decompose, for precipitates of inorganic wastes to form, for preheating the wet feedstock in preparation for subsequent separation of sulfur contaminants, or combinations thereof. Treatment further includes separating the precipitates out of the wet feedstock, removing sulfur contaminants, or both using a solids separation unit and a sulfur separation unit, respectively. Having removed much of the inorganic wastes and the sulfur that can cause poisoning and fouling, the wet biomass feedstock can be exposed to the heterogeneous catalyst for gasification.

摘要： A treatment method for containers of hazardous materials, including chemical and conventional weapons, is described. The method is applicable to munitions containing explosives and chemical warfare agents, and to training or test rounds. The containers are subjected to a highly corrosive fluid which dissolves all or part of the container and renders the containers useless as munitions. The highly corrosive fluid may render the hazardous material non-hazardous. The result of the treatment is a liquor which can undergo further treatment for recovery or disposal.
