Pyrolysis studies on agricultural (rice straw), forest (pine) and aquatic (Ulva lactuca) biomass were carried out in a fixed bed reactor at different temperature range of 300–550 °C. The product distributions and their characterization of products were compared among these biomasses. The maximum liquid product yield 29.4, 57.5 and 25.6 wt% obtained at 400, 500 and 400 °C respectively from rice straw (RS), pine (PN) and Ulva lactuca (UL) biomass. However, the higher conversion was observed in the case of pine wood biomass 77.0% at 550 °C. From the GC-MS analysis, it is observed that RS and PN bio-oil mostly composed of derivatives of phenolic compounds, while UL bio-oil composed of cyclopentenone derivatives compounds. The highest higher heating value (HHV) was found in pine bio-oil 34.8 MJ/kg. Also PN pyrolytic bio-oil had higher boiling point differences compounds. The bio-char analysis showed that the PN bio-char is a carbon rich and porous in nature as compared to the RS and UL bio-char.

在固定床反应器中，在300–550°C的不同温度范围内，对农业（稻草），森林（松树）和水生生物（Ulva lactuca）生物质进行了热解研究。在这些生物质中比较了产物分布及其产物表征。在400、500和400°C下分别从稻草（RS），松木（PN）和Ulva lactuca（UL）生物质中获得的最大液体产品收率为29.4、57.5和25.6 wt％。但是，在550°C的松木生物量为77.0％的情况下，观察到较高的转化率。从GC-MS分析可以看出，RS和PN生物油主要由酚类化合物的衍生物组成，而UL由环戊烯酮衍生物组成的生物油。在34.8 MJ / kg的松树生物油中发现最高的最高发热量（HHV）。PN热解生物油还具有较高沸点差异的化合物。生物炭分析表明，与RS和UL生物炭相比，PN生物炭本质上是富含碳且多孔的。
