摘要： The use of base/clay composites materials as sorbents for the removal of SO.sub.2 and SO.sub.3 (SO.sub.x) from flue gas and other sulfur containing gas streams is described. The base is either an alkaline earth metal carbonate (eg. CaCO.sub.3) or hydroxide (eg. Ca(OH).sub.2) is incorporated onto the clay by precipitating from corresponding metal oxide (eg. CaO) in an aqueous clay slurry. A second metal oxide or oxide precursor, preferably selected from transition metal ions, capable of promoting the oxidation of sulfur dioxide to sulfur trioxide, is incorporated to the base/clay composite during the synthesis in the form of finely divided metal oxide powder, metal oxide sol, water soluble metal salt or as clay-intercalated metal cation. The use of clay as dispersing agent for both the basic oxide and the second metal oxide component decreases the particle agglomeration of base particles and increases the rate of SO.sub.x uptake compared to the bulk bases in current use.

摘要： A process for removing noxious sulfur oxides, nitrous oxides, and chlorine from gas streams, particularly from flue gases of coal-burning power plants, using layered double hydroxide (LDH) sorbents are described. The sorbents are particularly useful for SO.sub.2 absorption at temperatures in the range 100 to less than 400.degree. C. The SO.sub.2 gas absorbs into the hydrotalcite structure as SO.sub.3.sup.2- anions by replacing most of the gallery CO.sub.3.sup.2- anions. The adsorbed SO.sub.2 is driven-off by calcination at elevated temperatures (500.degree. C.) and the LDH sorbents are regenerated by hydrolyzing the calcined product optionally in the presence of CO.sub.2 or CO.sub.3.sup.2-.
摘要翻译：描述了使用层状双氢氧化物（LDH）吸附剂从燃气流，特别是燃煤发电厂的烟道气中除去有害硫氧化物，一氧化二氮和氯的方法。吸附剂在100至小于400℃的温度下对SO2吸收特别有用。SO2气体通过替代大部分的CO32-阴离子而吸收到作为SO32-阴离子的水滑石结构中。吸附的SO2通过在高温（500℃）下煅烧而被驱除，并且通过在CO 2或CO 2 2-存在下水解煅烧产物来再生LDH吸附剂。
