    摘要： An alumina support comprises alpha-alumina as the main crystal phase of its backbone, and having a specific surface area of no higher than 3.0 m2/g, a pore volume ranging from 0.3 ml/g to 0.8 ml/g, an alkaline earth metal content ranging from 0.05% to 2.0% by weight of the support, wherein the support has such properties that treating the support with an aqueous oxalic acid solution having a concentration ranging from 0.4% to 2.0% by weight and having twice the weight of the support for 30 minutes can produce a leach liquor having an aluminum content of no higher than 60 μg/mL, a sodium content of no higher than 20 μg/mL, and a silicon content of no higher than 40 μg/mL. Processes for preparing the alumina support, silver catalysts comprising the alumina support, and methods of preparing ethylene oxide by ethylene oxidation using the silver catalyst are also disclosed herein.

    摘要： 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.
