  • Patent number: 9193593
    Abstract: An environmentally beneficial process for the production of fuels and chemicals employs carbon dioxide from a natural source or from an artificial chemical source that would otherwise be discharged into the environment. The carbon dioxide is converted to formic acid and the formic acid is then non-biologically converted to fuels and/or chemicals without the intermediate process of hydrogenating the formic acid to methanol or reacting the formic acid with ammonia to form formamide. In the present process, formic acid is converted to one of seven primary feedstocks: formaldehyde, acrylic acid, methane, ethylene, propylene, syngas, and C5-C7 carbohydrates. The formaldehyde, acrylic acid, methane, ethylene, propylene, syngas and/or short chain carbohydrates can either be used directly, or can be converted into a wealth of other products.

  • Patent number: 5437686
    Abstract: Bleaching compositions comprising an inorganic peroxygen compound and a bicyclic or tricyclic diketone as an activator for the peroxygen compound. The composition preferably comprises about 1 to about 75% of the peroxygen bleaching compound and about 1 to about 75% of the bicyclic or tricyclic diketone bleaching compound activator. The conventional additives such as surfactants, antifoaming agents, fabric softeners, stablizers, inorganic builder salts, buffers, enzymes and the like may be present as indicated. The compositions can be formulated as dry concentrated, aqueous solutions, aqueous solutions containing non-aqueous solvents, etc. The compositions are environmentally safe, effective as bleaching agents from below room temperature to higher temperatures, biodegradable and otherwise highly desirable.
