    摘要: PURPOSE: A transalkylation catalyst for producing mixed xylene from aromatic compounds containing sulfur impurities is provided to obtain a sulfur resistance function and a hydrogenation function. CONSTITUTION: A transalkylation catalyst includes a zeolite carrier and a noble metal, a second metal, and a third catalytic component carried in the carrier. The noble metal is selected from a group consisted of Pt, Pd, Au, and Ru. The second metal is cobalt or molybdenum. The third catalytic component is nickel phosphite (Ni2P), tungsten carbide, molybdenum sulfide, or a mixture thereof.
