  • Patent number: 10920390
    Abstract: A method for an ex-situ carbonization and solidification of silt soil using an active magnesium oxide, pertaining to the field of civil and hydraulic engineering. The method includes the steps of silt pretreatment, homomixing of solidifying agents, silt granulation, carbonization by carbon dioxide, exhaust gas/waste liquid collection, and resource utilization. In the method, the supply amount of the solidifying agent is adjusted through the actual measurement of the moisture content, and the granule size and carbon dioxide pressure are adjusted according to the soil properties. Therefore, a full mixing of the silt with the solidifying agents and a rapid carbonization of the magnesium oxide solidified silt granules can be achieved. Moreover, the dust and carbon dioxide can be absorbed during the operation, thereby avoiding secondary pollution. The silt carbonized granules can be used as filling materials for roadbeds, airport runways, engineering backfills, etc.

    Abstract: The disclosure discloses cerium sulfate chelated sulfur dioxide, a preparation method and a use thereof. The cerium sulfate chelated sulfur dioxide has a molecular formula of Ce[SO4][SO2].2H2O. It is a white crystal and the preparation method thereof may comprise the following steps: adding anhydrous cerium sulfate to dilute sulfuric acid with stirring for dissolvation; adding a solvent followed by refluxing at 45-50° C. for 2.0-2.5 h; heating the reaction product to remove the solvent, cooling to 20° C. or lower, and adding dilute sulfuric acid to allow precipitation of all crystals; cooling down the product followed by suction filtration, washing the obtained crystals by the solvent, so that crude cerium sulfate chelated sulfur dioxide can be obtained. The solubility of the cerium sulfate chelated sulfur dioxide of the disclosure has been significantly improved compared to the anhydrous cerium sulfate.

  • Publication number: 20200198013
    Abstract: The present invention provides a method to achieve full densification and grain size control for sintering metal materials. First, raw material powder is deagglomerated to obtain deagglomerated powder with dispersion. The deagglomerated powder is granulated by spray granulation. The granulated particles are processed by high-pressure die pressing and cold isostatic pressing. The powder compact is sintered by two-step pressureless sintering. The first step is to heat up the powder compact to a higher temperature and hold for a short time to obtain 75-85% theoretical density; the second step is to cool down powder compact to a lower temperature and hold for a long time. The two-step sintering can decrease the sintering temperature, so that the powder compact can be densified at a lower temperature. Thus, the obtained refractory metal product is densified, with ultrafine grains, uniform grain size distribution, and outstanding mechanical properties.
