Help: Producing SO2 from phosphogypsum and industrial-grade calcium sulfide
Thread Content
To produce SO2 by reacting phosphogypsum with industrial-grade calcium sulfide, it is necessary to determine the molar ratio of industrial-grade calcium sulfide to phosphogypsum, which is 1:3. After preparing the mixture in this ratio, the sample must be shaped into a cone or cylinder, using the methods used in the coal industry to determine high-temperature melting properties. Is there any good adhesive that can make them pliable so they can be shaped into cones or cylinders? The coal industry uses dextrin aqueous solutions; since CaS dissolves in water and phosphogypsum dissolves in glycerin, this system is not considered very suitable. Do any of you have any good binders or methods?
