    摘要: A method for preparing a suspension of LDH particles comprises the steps of preparing LDH precipitates by coprecipitation to form a mixture of LDH precipitates and solution; separating the LDH precipitates from the solution; washing the LDH precipitates to remove residual ions; mixing the LDH precipitates with water; and subjecting the mixture of LDH particles and water from step (d) to a hydrothermal treatment step by heating to a temperature of from greater than 80° C. to 150° C. for a period of about 1 hour to about 48 hours to form a well dispersed suspension of LDH particles in water.

    摘要: A dry material is synthesized by alkali metal (Li, Na and K) promoted calcium aluminate carbonates to obtain a CO2 sorbent used at a temperature higher than 600 Celsius degrees (° C.). The key composition of the sorbents is 52˜69% of CaO, which is beneficial to capture CO2 at 400˜800° C. A breakthrough result is achieved by using this sintering-resistant sorbent, which includes the features of 50% initial carbonation capacity and 20 folds CO2 capturing performance maintained after 40˜60 hours. Besides, alkali bearing material provides good velocity in CO2 capturing/releasing cycles; for example, by using Li and K series sorbents, 40 hours is required for 40 cycles only.

    摘要: The present invention provides an essentially dry method for preparation of enhanced alumina powders. The first step involves rapid calcination of an aluminum compound to produce alumina powder. The alumina powder is mixed with solid ammonium carbonate and a small amount of water. This mixture heats itself although some external heat is helpful to produce ammonium aluminum hydroxycarbonate (dawsonite-type) NH4AlCO3(OH)2 upon curing which is then decomposed to produce enhanced alumina having a specific desired morphology and nano-sized dimensions.

    摘要: Disclosed is a clean method for preparing layered double hydroxides (LDHs), in which hydroxides of different metals are used as starting materials for production of LDHs by atom-economical reactions. The atom efficiency of the reaction is 100% in each case because all the atoms of the reactants are converted into the target product since only M2+(OH)2, M3+(OH)3, and CO2 or HnAn− are used, without any NaOH or other materials. Since there is no by-product, filtration or washing process is unnecessary. The consequent reduction in water consumption is also beneficial to the environment.
