摘要
Abstract
The Y zeolite with sheet-like morphology was synthesized by directing agent method,using polyethyleneglycol-600 as the morphology control agent and dispersion agent.Characterization of the molecular sieves and the catalysts was performed using SEM,XRD,N2adsorption-desorption,Py-FTIR and NH3-TPD.Results showed that the prepared sheet-like molecular sieve had high external specific surface area.The catalytic cracking properties of the catalysts prepared with industrial octahedral and sheet-like NaY zeolites were investigated by using 1,3,5-triisopropylbenzene as the probe molecule.The experimental results showed that the catalyst with sheet-like morphology displayed higher conversion of 1,3,5-triisopropylbenzene and cracking products selectivity,compared to the industrial octahedral zeolite.关键词
