摘要

Nano-HZSM-5/γ-Al₂O₃ composite catalysts were prepared by employing mesoporous γ-Al₂O₃ as supports. Their structures, morphologies and acidity were characterized using powder X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR) analysis, N₂ adsorption and desorption measurement, scanning electron microscope and the NH₃ temperature-programmed desorption. Nano-HZSM-5 was uniformly dispersed and grown on the surface of γ-Al₂O₃ carrier. Nano-HZSM-5/γ-Al₂O₃ also showed a proper acidity with the uniform acid density distribution. The catalytic pyrolysis of waste tires was carried out in a micro-reactor system, and the composition of the product was analyzed on-line by gas chromatography. The selectivity to light olefins of nano-HZSM-5/γ-Al₂O₃ reached 29.9%, which was higher than that of nano-HZSM-5 zeolites, γ-Al₂O₃ and the mixture of nano-HZSM-5 and γ-Al₂O₃ with the same composition as nano-HZSM-5/γ-Al₂O₃.
