  • Patent number: 7427302
    Abstract: A compact solid source of hydrogen gas, where the gas is generated by contacting water with micro-disperse particles of sodium borohydride in the presence of a catalyst, such as cobalt or ruthenium. The micro-disperse particles can have a substantially uniform diameter of 1-10 microns, and preferably about 3-5 microns. Ruthenium or cobalt catalytic nanoparticles can be incorporated in the micro-disperse particles of sodium borohydride, which allows a rapid and complete reaction to occur without the problems associated with caking and scaling of the surface by the reactant product sodium metaborate. A closed loop water management system can be used to recycle wastewater from a PEM fuel cell to supply water for reacting with the micro-disperse particles of sodium borohydride in a compact hydrogen gas generator. Capillary forces can wick water from a water reservoir into a packed bed of micro-disperse fuel particles, eliminating the need for using an active pump.

  • Patent number: 7150766
    Abstract: The invention provides a method for forming particles of a target substance, comprising (a) co-introducing into a particle formation vessel, under controlled temperature and pressure, a supercritical or near-critical anti-solvent fluid; a first target substance in a first vehicle; and a second target substance in a second vehicle; and (b) using the anti-solvent to disperse the target substances in their respective vehicles and to extract the vehicles, substantially simultaneously and substantially immediately on introduction of the fluids into the particle formation vessel. The second vehicle is immiscible with the first, and contact between the first and second vehicles occurs a sufficiently short period of time before their dispersion by the anti-solvent, and with sufficient physical mixing, as to allow only insignificant, if any, phase separation to occur between the two vehicles between their contact with one another and their dispersion.

  • Patent number: 6884268
    Abstract: Process for the preparation of granules from a liquid composition by spraying the liquid composition in the granulation zone of a granulating device onto or over solid particles present in the granulation zone that are being kept in motion, as a result of which these particles grow, and withdrawing a stream of particles from the granulation zone, yielding a stream of particles of the desired size, with a part of the air flow leaving the granulating device during granulation being returned to the granulating device. In this way only a small part of the air flow needs to be purified of the starting materials.

  • Patent number: 6866688
    Abstract: The invention relates to an evaporative crystallization process to make salt compositions that includes a step wherein a mother liquor is formed that contains an effective amount of a crystal growth inhibitor that is selected from oligopeptides, polypeptides, and polymers bearing two or more carboxylic acid groups or carboxyalkyl groups and optionally further phosphate, phosphonate, phosphino, sulfate, and/or sulfonate groups, such as carboxymethyl cellulose with phosphate groups, to form salt crystals with a (111) face. The salt can be washed with a reduced amount of washing water while still containing lower amounts of K, Br, SO4, and/or Ca. A wet salt can be obtained by partially drying the salt crystals that are formed.

  • Patent number: 6660049
    Abstract: Process of crystallization of sodium bicarbonate from solution mined Nahcolite pregnant liquor comprising the use of from about 2 to 100 parts per million of lecithin, introduced full strength, made miscible in water with a soap or detergent, saponified with NaOH at a pH of 10-12, or preferably as a mixture of lecithin in pregnant or barren liquor containing HCO3−/CO3= ions at a pH in the range of from about 8 to 12, preferaby 8-10. The lecithin functions as a crystal growth modifier, producing improved crystal yields, product size classification, improved crystal shape including reduction in dendritic, branched and twinned forms, very significant scale reduction, reduction in wet cake moisture, increase in product bulk density, reduction in both oversize and undersize fractions (the classification phenomenon) and less breakage during drying and handling.
