摘要：NOVELTY - A catalyst comprises (wt.%) aluminum oxide (30-70), molecular sieve (30-70), and lanthanide, phosphorus, tungsten, niobium and/or molybdenum-containing compound (0-40). USE - A catalyst for removing olefin (claimed) in aromatic hydrocarbon. ADVANTAGE - The catalyst can maintain its high catalytic activity for a long time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of catalyst comprising: (A) uniformly mixing alumina and molecular sieve powder, adding lanthanide, phosphorus, tungsten, niobium and/or molybdenum-containing compound, and mixing with an acid; or dissolving lanthanide, phosphorus, tungsten, niobium and/or molybdenum-containing compound to an acid, adding solution to mixture of alumina and molecular sieve, and mixing; and (B) extruding the mixture into strips and roasting for 3-9 hours at 350-750 degrees C.
