Abstract: PURPOSE: A catalyst for removing sulfur dioxide of dibenzothiophene sulfone and a method for manufacturing biphenyl using the same are provided to efficiently remove a sulfur compound from the dibenzothiophene sulfone by a complex oxide catalyst. CONSTITUTION: Nitric acid cesium is manufactured. Cesium is impregnated in MCM-41 during incipient wetness. MCM-41 catalyst is obtained. A fixed layer continuous-type reactor is filled with the MCM-41 catalyst. Toluene including dibenzothiophene sulfone 500 ppm is put into in the reactor. A dibenzothiophene sulfone decomposition reaction is enforced. The dibenzothiophene sulfone is converted into biphenyl.
