改性橄榄石对C7H8/CO2催化重整的影响
Effects of modified olivine on the CO2 reforming of toluene
摘要
Abstract
An olivine catalyst was tested in a fixed bed reactor in CO2 reforming of the toluene as a tar model molecule produced during biomass gasification.The olivine catalyst was characterized by XRD, SEM, BET, H2-TPR;and the effects of the operating parameters (reforming reaction temperature and CO2 concentration) and catalyst preparation parameters(calcination temperature and nickel content) on the activity and selectivity for toluene conversion were examined.The results show that the olivine catalyst can increase the toluene conversion and lower the carbon formation.The toluene conversion also increases with the reforming temperature rise.The calcined olivine reaches the highest activity when the calcination temperature is 900℃.The CO2 addition can reduce the carbon formation obviously by 17.0% when the CO2/C7H8 molar ratio is 4.Moreover, the Ni/olivine catalyst has a better performance and the toluene conversation is up to 99.4%, while the carbon formation increases a little bit.关键词
