  • Patent number: 10604894
    Abstract: The present invention provides a method of carbonating carbon dioxide with high purity using a paper mill waste sludge by preparing a paper mill waste sludge which is a waste product discharged during the production of papermaking, adding acid to the paper mill waste sludge and reacting the acid therewith to produce a mixed solution and stirring, separating a supernatant of the mixed solution into an eluate, adding a basic substance to the eluate and adjusting pH to precipitate some of the ions in the eluate, and then adding a reaction initiator to the eluate in which some ions are precipitated and removed, and injecting carbon dioxide for a carbonation reaction.

  • Patent number: 9683104
    Abstract: Provided is a surface modification method of calcite powder prepared from desulfurized gypsum and heat-treated at a high temperature. According to the surface modification method, hydrophilic calcite powder having polarity may be changed into hydrophobic non-polar calcite powder by safely adsorbing a surface modifier onto a surface of the calcite powder and coating the surface with non-polar fatty acid. Particularly, in the case in which calcite powder heat-treated at a high temperature is hydrophobized, a significantly excellent hydrophobic surface property may be implemented.

  • Patent number: 9056781
    Abstract: Provided is a method of synthesizing high-purity calcite capable of controlling a grain size thereof, by reacting an aqueous calcium chloride solution with CO2 gas under strong alkaline condition, to crystallize into white and ultra-fine grain calcite. The method of synthesizing fine-grain calcite according to the present disclosure can decrease super-saturation by producing calcite under the strong alkaline conditions, thereby suppressing generation and growth of grain, resulting in controlling the grain size. Therefore, the above method is useful in producing high-purity ultra-fine grain calcite and can control the grain size of calcite from several hundreds of nanometers to several tens of nanometers by regulating the concentration of an aqueous caustic soda solution.

  • Publication number: 20130287672
    Abstract: Provided is a method for fixing carbon dioxide, the method includding: pulverizing furnace slag; mixing water and the furnace slag such that the furnace slag is present in a concentration of 5˜15 parts by weight based on 100 parts by weight of water; adding NaOH to the mixture; and supplying carbon dioxide to the decomposed mixture, and then carrying out a hydrothermal reaction, so that carbon dioxide can be stably fixed; the treatment of the furnace slag can lead to ecofriendly effects; and the use of the furnace slag can lead to production of carbonate minerals as the final product.
