1. A process for the catalytic conversion of gas mixtures, said process comprising:
contacting a process stream with a zeolitic catalyst, the zeolitic catalyst having an MFI framework and comprising 0.1 to 10 percent by weight of a zinc compound; and
converting at least part of the process stream to aromatic compounds comprising benzene, toluene and xylenes,
wherein the process stream comprises lower hydrocarbons and one or more sulfur compounds, wherein the lower hydrocarbons are at least 50% by volume of ethane,
wherein at least one selectivity of the following is achieved:
