摘要：
In order to investigate the effects of pyrolysis temperature, carrier gas flow rate and condensation temperature on the distribution characteristics of pyrolysis products of walnut shell, experimental study is conducted on the fixed-bed biomass pyrolysis reactor incorporated with multi-stage condensation columns. Results show that yield of liquid products continuously increases and finally levels off with the rising pyrolysis temperature. Carrier gas flow rate and fractional condensation temperature have minimal influence on the total yield of liquid products, while fractional condensation temperature has obvious effects on the yields of fractions. GC/MS analysis reveals that yield of phenolic products reach to the maximum with the pyrolysis temperature range from 450℃ to 500℃. Enrichment degree of phenolic products is improved, and enrichment degree of acid and yield of the second fraction are decreased with the increasing condensation temperature. © 2021, Solar Energy Periodical Office Co., Ltd.
