ABSTRACT OF THE DISCLOSURE "IMPROVED CATALYSTS" An improved catalyst for conversion of oxygen-containing ali phatics to hydrocarbons is a silica xerogel having a layer of an aluminium compound chemically bonded onto its surface, having a maxi- mum pore diameter of 1.1 nm and having substantially only protons and/or transition metal cations as electrical charge balancing species. The catalyst is very specific for the production of aromatics, if the reaction and calcination temperatures fall into given ranges. Certain catalysts show high selectivity for the production of toluene.
