    Abstract: The invention relates to a process for producing BTX comprising: (a) contacting a feedstream comprising C5-C12 hydrocarbons in the presence of hydrogen with a reforming catalyst to produce a reformed product stream, wherein the reforming catalyst comprises a hydrogenation metal and a support of an amorphous alumina, (b) contacting the reformed product stream in the presence of hydrogen with a hydrocracking catalyst to produce a hydrocracking product stream comprising BTX, wherein the hydrocracking catalyst comprises a hydrogenation metal and a zeolite and (c) separating the BTX from the hydrocracking product stream, wherein the hydrocracking catalyst comprises 0.01-1 wt %, preferably 0.01-0.5 wt %, of the hydrogenation metal in relation to the total catalyst weight and the zeolite has a pore size of 5-8 A and a silica (SiO2) to alumina (AI2O3) molar ratio of 5-200, preferably 30-120, wherein step (b) or steps (a) and (b)_are performed at a temperature of 425-580° C., a pressure of 300-5000 kPa gauge and a Weight Hourly Space Velocity of 0.1-15 h−1 preferably 0.1-10 h−1.
