摘要

为了研究生物质的热解温度及粒径对热解产物分布及产物特性的变化规律，将俄罗斯樟子松制成不同粒径(0.5～1、5～5.5 mm)在不同温度(350、500、650和800℃)下进行热解，考察不同的产物分布随热解条件的变化，采用元素分析及工业分析、FTIR和Raman分析热解后生物质焦结构随热解温度、粒径的变化规律，利用GC-MS分析热解油的变化规律。实验产率结果表明，随着温度升高，热解焦产率减少、热解气产率增大、热解油产率先增大后减小；粒径减小有利于热解气的生成。FTIR结果表明，随着温度升高，热解焦中—OH、C═O、C—O迅速降低。Raman结果表明，随着温度升高，I

增大，I

ALL

减小，表明焦中碳微结晶结构和不定型碳含量增加，粒径的减小则有助于颗粒物内部大型芳香结构生成。热解气结果表明，温度升高有利于CH

和H

的生成，粒径减小有利于CO生成。GC-MS结果表明，热解油中含有大量醇、酸、酮、酚及糖类物质，且含量受温度影响显著。

Abstract

In order to study the changes of biomass pyrolysis temperature and particle size on the distribution and characteristics of pyrolysis products

Russian Scotch pine was made into different particle sizes （0.5-1 and 5-5.5 mm） and pyrolyzed at different temperatures （350

500

650 and 800℃）.The changes of different product distribution with pyrolysis conditions were investigated.The bio-char structure were analyzed by elemental analysis

industrial analysis

FTIR and Raman

and the changes of pyrolysis oil with

pyrolysis conditions were analyzed by GC-MS.The results show that the yield of bio-char decreases

and the yield of pyrolysis gas increases

and the yield of bio-oil first increases and then decreases with the increase of temperature.The decrease of particle size is conducive to the formation of pyrolysis gas.FTIR results showed that—OH

C═O and C—O in bio-char decreased with the increase of temperature and pressure.Raman results show that with the increase of temperature

increases and I

ALL

decreases

indicating that the carbon microcrystalline structure and amorphous carbon content in the char increase

but no significant graphitization structure is formed.The decrease of particle size is conducive to the formation of large aromatic structure in the particles.The results of pyrolysis gas show that the increase of temperature is conducive to the formation of CH

and H

and the decrease of particle size is conducive to the formation of CO

.The results of GC-MS show that the pyrolysis oil contained a large number of alcohols

acids

ketones

phenols and sugars

which changed significantly under the influence of temperature.
