To obtain a highly active and highly selective catalyst almost free from a catalytic deterioration suited for converting to toluene and an aromatic hydrocarbon compound by causing one type of metal selected from among the group VIII and VIA metals of the periodic table and its chemical compound to be borne by a carrier containing a specific zeolite.
This catalyst for converting to an aromatic hydrocarbon compound is best suited for converting an aromatic hydrocarbon compound with a boiling range of 100-210°C and the number of carbon atoms of at least, 9 contained in a stock oil not containing benzene, to toluene and a 8C aromatic hydrocarbon compound in the presence of hydrogen. In addition, this catalyst is formed by causing at least, one type of metal selected from among the group VIII metal and the group VIA metal of the periodic table or its chemical compound to be borne by a carrier containing zeolite with the maximum pore diameter of 0.6-1.0nm of a micropore and an SiO2/Al2O3 ratio of at least 50. The ideal zeolite is mordenite or Y-type zeolite.
