Catalytic formulation for producing propylene cyclic carbonate from carbon dioxide using a potassium iodide catalyst

A catalytic formulation comprising:

• a) a support material made of an aluminum oxyhydroxide or aluminum oxide within a weight ratio between 30 and 90%;
• b) a carbonaceous material in a weight ratio between 1 and 60%;
• c) a polymeric material soluble in water or in slightly acid solutions with the presence of oxydrile groups, within a weight ratio between 1 and 45%;
• d) a salt promoting the presence of phosphate ions within a weight ratio between 1 and 30%;
• e) an aqueous acid agglutination agent at a weight ratio between 1 and 15%, and wherein the aqueous the acid agglutination agent is selected from the group consisting of aqueous solutions of formic acid, acetic acid, nitric acid, and mixtures thereof;
• f) an alkaline metal halogen within a weight ratio between 1 and 80%, and wherein the alkaline metal halogen comprises potassium iodide;
• g) the catalyst promoting a cycloaddition reaction between carbon dioxide and propylene oxide for producing propylene cyclic carbonate;
• and
• h) the catalyst having been subjected to a ramped calcination heating procedure starting at room temperature to a final temperature of 450° C. followed by cooling to room temperature.
