With CTAB as template,theβ/MCM-41 micro-mesoporous composite molecular sieve has been synthesized by selfassembly of the zeolite structure fragments and the structural units obtained by alkali-treatedβzeolite,and the effects of the alkali solution concentration,CTAB dosage in the synthesis process ofβ/MCM-41 was investigated.The β/MCM-41 composite molecular sieve with well long-range order can be synthesized under the optimum conditions:The solution concentration of NaOH is 1.5 mol/L and the mass fraction of CTAB is 10%.Then the Ce-β/MCM-41 composite molecular sieve doped skeleton with rare earth metal Ce was synthesized and the effect of Ce doping amount(Ce/β=0.03,0.08)on Ce-β/MCM-41 was investigated.The result shows that the 0.03-Ce-β/MCM-41 had a well long-range order.The effect of acetylation reaction conditions on the yield of p-MOAP was investigated by using 0.03-Ce-β/MCM-41 as a catalyst in a fixed bed.The single-factor experiments showes that the 4.0 hp-MOAP yield is 58.6% under the conditions:The velocity of the reactants flow is 65 mL/h,the LHSV is 6.5 h~(-1),reaction temperature is 140 ℃ and n(AN)/n(AA)=6.0.
