THE PRESENT INVENTION RELATES TO A PROCESS FOR THE CONVERSION OF HYDROCARBONS INTO AROMATIC COMPOUNDS, IN PARTICULAR FOR THE CATALYTIC REFORMING OF GASOLINES AND FOR THE PRODUCTION OF AROMATIC COMPOUNDS FROM PARAFFIN AND NAPHTHENE HYDROCARBONS, PROCESS DURING WHICH THE LOAD TO BE PROCESSED IS SUBJECTED TO THE ACTION OF A CATALYST. THIS CATALYST COMPRISES A MATRIX CONSISTING OF 0 TO 100BY WEIGHT OF h TRANSITION ALUMINA, THE REMAINING WEIGHT PERCENT UP TO 100BEING THAT OF g TRANSITION ALUMINA AND: -AT LEAST ONE DOPING METAL CHOSEN FROM THE GROUP OF ALKALI METALS AND ALKALINE-EARTH METALS, -AT LEAST ONE HALOGEN CHOSEN FROM THE GROUP MADE UP OF FLUORINE, CHLORINE, BROMINE AND IODINE, -AT LEAST ONE NOBLE METAL FROM THE PLATINUM GROUP, AND -AT LEAST ONE PROMOTER METAL CHOSEN FROM THE GROUP MADE UP OF TIN, GERMANIUM, INDIUM, GALLIUM,THALLIUM, ANTIMONY, LEAD, RHENIUM, MANGANESE, CHROMIUM, MOLYBDENUM AND TUNGSTEN, SAID CATALYST HAVING BEEN SUBJECTED TO ADDITIONAL HYDROTHERMAL TREATMENT AT A TEMPERATURE OF 300 TO 1000°C, IN A GAS ATMOSPHERECONTAINING STEAM.
