Abstract

Abstract: Using rectorite extrudates from calcined rectorite powder as the starting material,a series of ZSM-5/rectorite composites were prepared via the in-situ crystallization method.The physicochemical properties and propylene boosting performance of the resulting samples were characterized by using X-ray diffraction,scan-ning electronic microscopy/energy dispersive spectrometer,N₂ adsorption-desorption,and Fourier transformed in-frared spectroscopy of pyridine adsorption,respectively,and assessed by using Daqing atmospheric residue as feed-stock.The results showed that the ZSM-5/rectorite composites in which the ZSM-5 phase grows in-situ as a 2-3 μm thick layer on rectorite particles have a trimodal microporous-mesoporous-macroporous structure and thus exhibit outstanding propylene boosting performance.Compared with a commercial ZSM-5 incorporated fluid catalytic cracking catalyst,the ZSM-5/rectorite composite incorporated catalyst increased the yield and selectivity of pro-pylene by 2.44% and 5.35%,respectively.
