Latest Patents

Collier's patent, titled "Method of removal of COS from propylene," presents a novel approach to removing carbonyl sulfide from propylene through hydrolysis. This method utilizes a catalyst comprising platinum sulfide on alumina, with an improvement that involves regenerating the catalyst by contacting it with a solvent for polypropylene. The process ensures that any polypropylene on the catalyst is readily dissolved, thereby enhancing the overall efficiency of the purification process. The propylene is passed through a series of components, including a C.sub.3-splitter, a heater, and a platinum sulfide catalyst bed, culminating in a topping still where H.sub.2 S and CO.sub.2 are separated from the purified propylene. A preferred solvent for this process is liquid propylene.
