摘要: Abstract Catalytic steam reforming of coconut shell pyrolysis bio-oil over Fe/olivine catalyst was conducted in a fixed-bed quartz reactor. The effects calcination temperature, iron loading, reaction to carbon ratio (S/C), weight hourly space velocity (W b HSV) on gas composition and conversion were investigated. results indicate that has good activity for bio-oil, the couple Fe 2+/3+ /Fe 2+ may be sufficiently efficient C–C, C–O C–H breaking. After reforming, most phenolics oil are converted into light molecular compounds such as H 2 , CO, CO CH 4 . concentration enhanced by increasing temperature from 750 800 °C S/C 1.5 2, but decreased with temperature. In W HSV range 0.5–0.6, hydrogen obviously, whereas it slightly further HSV. highest 47.6 vol% obtained among catalysts tested, best 97.2% 10% under conditions temperature = 800 °C, HSV = 0.5, S/C = 2.
