摘要: Phenol plant waste water containing small amounts of phenol and sodium sulfate is successfully distilled through the addition of recovered sodium sulfate to enhance the volatility of the phenol relative to water; at least a portion of the sodium sulfate is recycled, while a significant portion of the phenol can be returned to the phenol plant for recovery.

摘要: Carbonyl sulfide is removed from propylene by hydrolysis over a catalyst comprising platinum sulfide on alumina. Specifically, the propylene is passed through, successively, a C.sub.3 -splitter, a heater, the platinum sulfide catalyst bed, and a topping still where the resulting H.sub.2 S and CO.sub.2 are separated from the purified propylene.

摘要: In a method of removing carbonyl sulfide from propylene by hydrolysis over a catalyst comprising platinum sulfide on alumina, the improvement comprising regenerating the catalyst by contacting the catalyst with a solvent for polypropylene under conditions such that any polypropylene on the catalyst will be readily dissolved. Specifically, the propylene is passed through, successively, a C.sub.3 -splitter, a heater, the platinum sulfide catalyst bed, and a topping still where resulting H.sub.2 S and CO.sub.2 are separated from the purified propylene. A preferred solvent is liquid propylene.
