CeO2对Ni-Cu/HZSM-5催化剂在生物油加氢脱氧反应中抗积炭性能的影响
Influence of CeO2 on the carbonaceous deposition behavior of Ni-Cu/HZSM-5 catalyst in the hydrodeoxygenation of bio-oil
摘要
Abstract
The influence of CeO2 as an additive on the carbonaceous deposition behavior of Ni-Cu/H-ZSM-5 catalyst in the hydrodeoxygenation ( HDO ) of bio-oil was investigated. Various techniques such as thermogravimetric analysis ( TGA ) , X-ray photoelectron spectroscopy ( XPS ) , and Raman spectroscopy were used to elucidate the content and microstructure of carbon deposited on the catalyst surface, the transformation of various forms of carbon ( soft carbon, hard carbon and graphite) in HDO, and the kinetics of carbon deposition. The results indicate that the content of CeO2 added in the Ni-Cu based catalyst and the reaction temperature both have a significant influence on the carbon deposition behavior and the resistance against coking for HDO of bio-oil;for HDO over the Ni-Cu/HZSM-5 catalyst at 270 ℃, adding 15% CeO2 gives the Ni-Cu catalyst highest resistance against the carbon deposition.关键词
