    摘要： Sulfur dioxide (SO 2 ) may be removed from carbon dioxide feed gas by contacting the carbon dioxide at an elevated temperature and an elevated pressure with a catalyst for oxidizing SO 2 , in the presence of oxygen (O 2 ) to convert SO 2 to sulfur trioxide (SO 3 ); contacting SOP 3 in the resultant SO 3 -enriched carbon dioxide gas with water to produce sulfuric acid and SO 2 -depleted carbon dioxide gas; and separating the sulfuric acid from the SO 2 -depleted carbon dioxide gas. If present, NO x is also removed from the carbon dioxide feed gas as nitric acid to produce SO 2 -depleted, NO x -lean carbon dioxide gas. The method has particular application in the removal of SO 2 and NO x from flue gas produced by oxyfuel combustion of a hydrocarbon fuel or carbonaceous fuel, within or downstream of the CO 2 compression train of a CO 2 recovery and purification system.

    摘要： This invention describes an integrated process for making ethylidene bisformamide in high yield wherein water, which is formed as a reaction by-product, is readily removed from the reaction product mixture without adversely affecting the efficiency of the overall process. The process contemplates isolating the reaction zone from the separation zone and comprises circulating a stream of formamide through a reaction zone containing a solid acidic catalyst and a separation zone; introducing acetaldehyde into the circulating stream of formamide to form a reaction mixture and contacting the reaction mixture with the solid acidic catalyst under reaction conditions sufficient to form a product mixture comprising ethylidene bisformamide and water; and separating water from the product mixture in the separation zone to form a water-depleted product mixture containing ethylidene bisformamide.
