REMOVAL OF ALKYNE IMPURITIES FROM DIOLEFIN CONTAINING MIXTURES THROUGH CRACKING OVER CUO/AL2O3 BASED MATERIALS

摘要

Processes to selectively crack alkyne compounds from a hydrocarbon stream including olefinic and di-olefinic compounds are described. The process includes contacting the hydrocarbon stream with a supported CuO catalyst under conditions sufficient to crack the alkynes to form a product stream that included cracked compounds and further separating the cracked organic compounds from the hydrocarbon stream.
