Pyrolysis studies on conventional biomass were carried out in fixed bed reactor at different temperatures 300, 350, 400 and 450°C. Agricultural residues such as corn cob, wheat straw, rice straw and rice husk showed that the optimum temperatures for these residues are 450, 400, 400 and 450°C respectively. The maximum bio-oil yield in case of corn cob, wheat straw, rice straw and rice husk are 47.3, 36.7, 28.4 and 38.1wt% respectively. The effects of pyrolysis temperature and biomass type on the yield and composition of pyrolysis products were investigated. All bio-oils contents were mainly composed of oxygenated hydrocarbons. The higher area percentages of phenolic compounds were observed in the corn cob bio-oil than other bio-oils. From FT-IR and H NMR spectra showed a high percentage of aliphatic functional groups for all bio-oils and distribution of products is different due to differences in the composition of agricultural biomass.
在不同温度（300、350、400 和 450°C）的固定床反应器中对常规生物质进行了热解研究。玉米芯、小麦秸秆、水稻秸秆和稻壳等农业废弃物的研究表明，这些废弃物的最佳温度分别为 450、400、400 和 450°C。玉米芯、小麦秸秆、水稻秸秆和稻壳的最大生物油产率分别为 47.3%、36.7%、28.4%和 38.1wt%。考察了热解温度和生物质种类对热解产物产率和组成的影响。所有生物油的主要成分均为含氧烃。与其他生物油相比，玉米芯生物油中酚类化合物的面积百分比更高。从 FT-IR 和 H NMR 谱图可以看出，所有生物油中都含有较高比例的脂肪族官能团，由于农业生物质组成的不同，产物的分布也不同。
