  • Publication number: 20150064092
    Abstract: Methods of producing fibrous solid carbon forests include reacting carbon oxides with gaseous reducing agents in the presence of a catalyst having a predetermined grain size to cause growth of fibrous solid carbon forests upon a surface of the metal. The fibrous solid carbon forests are substantially perpendicular to the surface of the metal thus creating the “forests”. A bi-modal forest composition of matter is described in which a primary distribution of fibrous solid carbon comprises the forest and a secondary distribution of fibrous solid carbon is entangled with the primary distribution. A reactor includes a catalyst, a means for facilitating the reduction of a carbon oxide to form solid carbon forests on a surface of the catalyst, and a means for removing the solid carbon forest from the surface of the metal catalyst.

  • Patent number: 8551437
    Abstract: A process for the production of a reaction product consisting essentially of P4O6 is carried out by reacting oxygen with phosphorus in an exothermic reaction in a reaction unit. Heat created by the exothermic reaction is removed by feeding P4O6 and/or by-products of the process into the reaction unit. The generated reaction product is then quenched to a lower temperature where no essential decomposition of the reaction product occurs, and at least part of P4O6 is separated from the reaction product obtained after quenching. The resulting yield of P4O6 based on the phosphorus used is improved and the heat of the exothermic reaction can be controlled in an economic way.

The reaction product is kept in the reaction unit at an average temperature in the range of 1600 and 2000 K by removing the heat created by the exothermic reaction of phosphorus and oxygen. A residence time of at least 1 second of the reaction product passing the reaction unit is maintained. The reaction product is then conventionally cooled in a quenching unit connected with the reaction unit. The final reaction product contains P4O6 with a very low content of elemental phosphorus.

  • Publication number: 20110147679
    Abstract: The present invention provides a method for recovering an oxide-containing battery material from a waste battery material. The recovery method includes steps (1) and (2) in this order: (1) a step of immersing a base taken out of the waste battery material and the base having an oxide-containing battery material, in a solvent that does not substantially dissolve the oxide, and stripping the battery material from the base thereby, and (2) a step of separating the battery material from the base.

  • Patent number: 7910080
    Abstract: A phosphorous pentoxide producing method includes forming a kiln bed using feed agglomerates with a calcium-to-silica mole ratio of from 0.5 to 1.0 and maintaining a bed temperature at or above 1260° C. along a portion of the bed length without exceeding 1380° C. along the entire bed length. Less than 10% of the agglomerates' phosphate input to the kiln remains in the kiln residue as phosphate. Another method includes maintaining a bed temperature at or above 1180° C. along a portion of the bed length and establishing a bed surface-to-volume ratio multiplied by a time for bed heat up to 1180° C. of less than 50 minutes-ft2/ft3.

  • Patent number: 7879303
    Abstract: Described is a method for the production of metal salts, wherein the cationic metal is preferably selected from Group I to IV metals and mixtures thereof and the anionic group is selected from phosphates, silicates, sulfates, carbonates, hydroxides, fluorides and mixtures thereof, and wherein said method comprises forming a mixture of at least one metal source that is a metal carboxylate with a mean carbon value per carboxylate group of at least 3 and at least one anion source into droplets and oxiding said droplets in a high temperature environment, preferably a flame. This method is especially suited for the production of calcium phosphate biomaterials such as hydroxyapatite (HAp,Cal0(P04)6(OH)2) and tricalcium phosphate (TCP,Ca3(P04)2) that exhibit excellent biocompatibility and osteoconductivity and therefore are widely used for reparation of bony or periodontal defects, coating of metallic implants and bone space fillers.
