Claim 17:
18. A process for the catalytic conversion of gas mixtures of lower hydrocarbons, which contain at least 50% by volume of ethane, to aromatic compounds comprising benzene, toluene and xylenes, said process comprising the steps of contacting a process stream containing lower hydrocarbons with a zeolitic catalyst having an MFI framework and containing 0.1 to 10 percent by weight of a copper compound, wherein the process stream further contains one or more sulfur compounds,
wherein at least one selectivity of the following is achieved:
the selectivity of methane does not exceed 5%,
the selectivity of aromatics with nine or more carbon atoms does not exceed 2%, or
the selectivity of ethylene is at least 30%.
