ABSTRACT:
In the process of converting an aromatic feedstock to an alkyl-substituted mono-nuclear aromatic product by contacting the feedstock with a coke-selectivated ZSM-5 type catalyst at elevated temperature under conversion process coking conditions to produce said alkyl-1-substituted mononuclear aromatic product selectively, the improvement which comprises:
regenerating the process coked catalyst in contact with a non-oxidizing atmosphere comprising an effective amount of hydrogen at a temperature of about 800.degree. F. to 1200.degree. F. to restore activity of the catalyst while retaining selectivity. Advantageously, the conversion involves alkylation, disproportionation and/or isomerization to produce at least one lower alkyl or dialkyl benzene product.
