Energy and exergy analyses were performed to evaluate the pyrolysis of the lignocellulosic biomasses, beech wood and flax shives, and the pyrolysis of biomass principal compounds (cellulose, hemicelluloses and lignin) as well. The reaction took place in a semi-continuous reactor at 500 °C within an intermediary pyrolysis regime. Lignin showed the lowest heat for pyrolysis, with 0.86 MJ/kg_{Raw material}, followed by cellulose (1.21 MJ/kg_{Raw material}) and hemicellulose (1.43 MJ/kg_{Raw material}). The heat for pyrolysis for the pseudo-components was inferior to those obtained for the biomasses. Beech wood heat for pyrolysis was 1.97 MJ/kg_Biomass and that for flax shives was 2.2 MJ/kg_Biomass. The thermal behavior of the biomasses was similar to that of hemicellulose and cellulose, as the bio-oils seemed to have closest energetic and exergetic distribution of chemical families as compared to the lignin bio-oil. For all pyrolysis tests, bio-oil represented the stream with lowest anergy. As values were between 0.08 and 0.57 MJ/kg_Bio-oil. Pyrolysis of the pseudo-components showed lower exergy destruction rate than pyrolysis of the biomasses; this can be a result of the competition of thermal reactions between cellulose, hemicellulose and lignin within the biomass during pyrolysis. Meanwhile, less exergy was destroyed in flax shives pyrolysis (2.00 MJ/kg_Biomass) than beech wood pyrolysis (2.1 MJ/kg_Biomass).

进行能量和火用分析以评估木质纤维素生物质、山毛榉木和亚麻碎屑的热解，以及生物质主要化合物（纤维素、半纤维素和木质素）的热解。该反应发生在半连续反应器中，温度为 500 °C，处于中间热解状态。木质素显示出最低的热解热，为 0.86 MJ/kg_原料，其次是纤维素（1.21 MJ/kg_原料）和半纤维素（1.43 MJ/kg_原料）。伪组分的热解热不如生物质的热解热。山毛榉木材的热解热为 1.97 MJ/kg_生物质，亚麻屑的热解为 2.2 MJ/kg_生物质. 生物质的热行为类似于半纤维素和纤维素的热行为，因为与木质素生物油相比，生物油似乎具有最接近的化学家族的能量和热分布。对于所有热解测试，生物油代表具有最低无能的流。由于值介于 0.08 和 0.57 MJ/kg_{生物油之间}。伪组分的热解比生物质的热解表现出较低的火用破坏率；这可能是热解过程中生物质内纤维素、半纤维素和木质素之间热反应竞争的结果。同时，亚麻碎屑热解（2.00 MJ/kg_生物质）比山毛榉木热解（2.1 MJ/kg_生物质）破坏的火用更少。
