    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.

    Abstract: PURPOSE: A process for manufacturing biphenyl from dibenzothiophene sulfone is provided to improve a conversion ratio of dibenzothiophene sulfone and to prepare biphenyl at a high yield. CONSTITUTION: A process for manufacturing biphenyl from dibenzothiophene sulfone comprises a step for preparing biphenyl by removing sulfur dioxide from dibenzothiophene sulfone in the presence of a magnesium-containing mesoporous molecular sieve catalyst. The magnesium-containing mesoporous molecular sieve catalyst is MCM-41 containing magnesium. The magnesium-containing mesoporous molecular sieve catalyst includes 20~40 weight% magnesium.
