    • A process for the conversion of a hydrocarbon load containing paraffin, naphthene and aromatic hydrocarbons having 5 to 12 carbon atoms into aromatic compounds, which entails contacting the load with a catalyst under temperature and pressure conditions to produce the aromatic compounds, the catalyst containing:a matrix consisting of 0 to 100% by weight of .eta. transition alumina, the remaining weight percentage of the matrix, up to 100%, consisting of .gamma. transition alumina, andat least one doping metal selected from the group consisting of alkali metals and alkaline-earth metals,at least one halogen selected from the group consisting of fluorine, chlorine, bromine and iodine,at least one noble metal selected from the platinum group, andat least one promoter metal selected from the group consisting of tin, germanium, indium, gallium, thallium, antimony, lead, rhenium, manganese chromium, molybdenum and tungsten,the catalyst having previously been hydrothermally treated at a temperature of 300 to 1,000.degree. C. in a gaseous atmosphere containing steam, the atmosphere also containing chlorine in a molar content of greater than 0 but no more than 20%.
