  • Process for converting a wet acetylene-containing stream to aromatics using a zinc-promoted, crystalline, borosilicate molecular sieve catalyst composition
    Patent number: 4982032
    Abstract: A process for the catalyzed conversion of wet acetylene-containing streams to an essentially aromatic product rich in aromatic compounds, particularly benzene, toluene and styrenes using a promoted catalyst composition made by incorporating a major amount of a HAMS-1B crystalline borosilicate molecular sieve composited in an inorganic matrix with a minor amount of a zinc compound and calcining the result to form a promoted catalyst composition containing supported zinc oxide.
