Study on Fast Pyrolysis of Wheat Straw in a Spouted Bed Reactor

This paper introduced the fast pyrolysis of wheat straw in a spouted bed reactor. A key parameter pyrolysis temperature was studied for the production of gases, liquid and chars from the fast pyrolysis of wheat straw. The experimental results showed that the maximum liquid yield is about 60%(daf.) at the range from 460℃ to 520℃. The bio-oil was composed of acetic acid, hydroxyacetaldehy, acetol, levoglucosan, furaldehyde, and a small quantity of phenols. The heating value of bio-oil from the fast pyrolysis of wheat straw was about 17.0 MJ·kg~(-1). The gases form wheat straw pyrolysis consisted of CO_2, CO, CH_(4),_( )H_2, and a little of alkenes.
