  • Composition containing at least sodium bicarbonate, preparation method therefor and uses thereof
    Patent number: 6290872
    Abstract: A composition having sodium bicarbonate, sodium carbonate, and ammonia in the form of ammonium salts is formed by heat treating ammoniacal bicarbonate at a temperature between 20 and 150° C. A method of using the composition includes reacting the composition with a flue gas containing HX acids, where X represents halogens, compounds of the SOx type, or mixtures thereof, or the flue gases may contain NOx compounds.

  • Cerium oxide with pores having a lamellar structure, preparation method therefor and use thereof in catalysis
    Patent number: 5994260
    Abstract: A cerium oxide with pores having a uniform lamellar structure. The pores may be at least partially arranged in substantially parallel directions and may also extend throughout the grain. The method for preparing said cerium oxide comprises heat treating a compound that essentially consists of cerium carbonate octahydrate. The atmosphere in which the treatment is performed includes an air/steam or oxygen/steam mixture with a steam volume fraction of at least 40%. Said cerium oxide is particularly useful as a catalyst, especially in motor vehicle post-combustion catalysis.
