Bio-Oil Production from Fast Pyrolysis of Corn Stalk in a Fluidized Bed

Abstract:

Fast pyrolysis of corn stalk was performed at temperatures in the range of 450 - 600 °C in a fluidized bed. The chemical composition of bio-oil was analyzed by GC–MS, and its main properties were determined. The results showed that the bio-oil yield increased with increasing pyrolysis temperature from 450 °C to 500 °C and then declined with a further increase in pyrolysis temperature. The highest bio-oil yield of 43.3wt% was obtained at 500 °C with the dolomite as bed material. The char yield always decreased with the rise of temperature. The major chemical compounds of bio-oil included hydroxyacetone, butanone, acetic acid, propionic acid, ethylene glycol, phenol, etc.
