    • The present invention discloses a novel use of the FGD byproduct from thermal power plants and facilities and the specific method for alkali soil amelioration. In this method, after sampling, amount of Na2CO3, NaHCO3, Mg(HCO3)2,±)Na and ±)Mg can be calculated by analysis. According to the component in FGD byproduct from thermal power plants and facilities, the amount for FGD byproduct from thermal power plants and facilities needed in the alkali soil to be ameliorated can be determined. The FGD byproduct from thermal power plants and facilities are scattered on the surface according to the alkalization degree. After irrigating, the soil is operated just like common land. This invention allows the FGD byproduct from thermal power plants and facilities to be utilized effectively and economically, changing from it from waste to a useful substance. Moreover, it provides a method for alkali soil amelioration, which is fast, efficient, consumes less water, is cost effective, and promising.

    • The present invention relates to sulfur tolerant catalyst composites useful for reducing contaminants in exhaust gas streams, especially gaseous streams containing sulfur oxide contaminants. More specifically, the present invention is concerned with improved NOx trap catalysts for use in diesel engines as well as lean burn gasoline engines. The sulfur tolerant NOx trap catalyst composites comprise a platinum component, a support, a NOx sorbent component, and a spinel material prepared by calcining an anionic clay material represented by the formula MmNn(OH)(2m+2n)Aa.bH2O, wherein the formula is defined herein. The sulfur tolerant NOx trap catalyst composites are highly effective with a sulfur containing fuel by trapping sulfur oxide contaminants which tend to poison conventional NOx trap catalysts used to abate other pollutants in the stream. The sulfur tolerant NOx trap catalyst composites are suitable for diesel engines because the composites can be regenerated at moderate temperatures with rich pulses, rather than at high temperatures.
    • 本发明涉及可用于减少废气流中的污染物,特别是含有硫氧化物污染物的气流的耐硫催化剂复合材料。 更具体地,本发明涉及用于柴油发动机以及贫燃汽油发动机的改进的NOx捕集催化剂。 耐硫NOx捕集催化剂复合材料包括铂组分,载体,NOx吸附剂组分和通过煅烧由式MmNn(OH)(2m + 2n)Aa.bH2O表示的阴离子粘土材料制备的尖晶石材料,其中 公式在本文中定义。 耐硫NOx捕集催化剂复合材料通过捕集硫氧化物污染物而非常有效地含硫燃料,硫氧化物污染物倾向于毒害用于消除流中其它污染物的常规NOx捕集催化剂。 耐硫NOx捕集催化剂复合材料适用于柴油发动机,因为复合材料可以在中等温度下以丰富的脉冲而不是在高温下再生。
