  • Patent number: 9675098
    Abstract: The present invention relates to stable and white iron fortification and iron+iodine double fortification agents, their preparation and use in fortification of salt. These agents help overcome the normal difficulties encountered in iron and iodine fortification such as low iodine stability on storage, development of colour and odour, and use of unwanted additives to impart stability. In one of the invented products, both iron and iodine coexist in stable manner in the same matrix which allow for a more uniform distribution of iodine. The process of preparation is demonstrated to be scalable and utilizes commonly available raw materials which would enable the products to be synthesized in affordable manner.

  • Patent number: 9475705
    Abstract: The present invention belongs to the synthesis technology field of inorganic functional materials, and particularly provides a self-balanced high-pressure and high-shear autoclave and its application in the preparation of layered double hydroxides (LDHs). In this invention, by imbedding the handpiece of emulsification mill into the autoclave, and by taking the motor driving system outside of the autoclave, the pressure of the autoclave can be highly stable by the use of self-balanced seal gland. These characters solve the problem that the typical emulsification mill cannot be used in high-pressure system, and ensure the crystallization under the high-pressure and high-shear conditions. Such autoclave takes the advantages of additional equipment, and eliminates the volume effect in the amplification process. By the use of this new autoclave, the reaction time can be shorten from 24 hours to 2-6 hours, the reaction temperature can be reduced from 180° C. to 140° C.

  • Patent number: 7758840
    Abstract: A method for producing a compound, in which carrier particles are made to adsorb and carry carried fine particles having a diameter smaller than that of the carrier particles. The method is characterized by comprising: a first step of charging the carrier particles or their precursors to a potential inverse to that of the carried fine particles or their precursors to adsorb the carrier particles or their precursors; and a second step of synthesizing the carried fine particles hardly soluble or their precursors, and causing the carrier particles or their precursors immediately after or during the synthesization to adsorb the hardly soluble carried fine particles or their precursors.

  • Publication number: 20100144521
    Abstract: Compositions comprising synthetic rock, e.g., aggregate, and methods of producing and using them are provided. The rock, e.g., aggregate, contains CO2 and/or other components of an industrial waste stream. The CO2 may be in the form of divalent cation carbonates, e.g., magnesium and calcium carbonates. Aspects of the invention include contacting a CO2 containing gaseous stream with a water to dissolve CO2, and placing the water under precipitation conditions sufficient to produce a carbonate containing precipitate product, e.g., a divalent cation carbonate.

  • Patent number: 7608209
    Abstract: The present invention relates to the use of a mixed carbonate of formula AB(CO3)2, in which A and B are different and chosen from alkali metals, alkaline-earth metals and rare earths, for the containment of radioactive carbon. This use may for example involve a process comprising: mixing CO2 having a radioactive carbon to be contained, or a simple carbonate of an alkali, alkaline-earth or rare-earth metal having a radioactive carbon to be contained, with an aqueous solution of a mixture of ACln and BClm or with an aqueous solution of a mixture of A(OH)n, and B(OH)m in order to obtain a precipitate of AB(CO3)2, where n and m are integers sufficient to compensate for the charge of A and B respectively; recovery of the AB(CO3)2 precipitate in powder form; and then pressing and sintering of the powder at a 20 temperature below the decarbonation temperature of the mixed carbonate manufactured in order to obtain sintered pellets of mixed carbonates for the containment of the radioactive carbon.
