It is very requisite to demonstrate the characterization of lignocellulosic biomass for converting into renewable fuels and valuable chemicals. In this work, the physicochemical and thermochemical characterization of some non-edible oil seeds such as Putranjiva (Putranjiva roxburghii), Amaltas (Cassia fistula), and Siris (Albizia lebbeck) were carried out by extractive analysis via Soxhlet solvent extraction, compositional analysis, proximate analysis, elemental (CHNSO) analysis, heating value, bulk density, crystallinity index via XRD, functional groups via FTIR, mineral content via EDX, slagging and fouling indices via XRF, and degradation profile via TGA. It was noticed that all seeds consist of a maximum percentage of extractives such as Putranjiva 50.55%, Amaltas 18.22%, and Siris 22.8%. The results showed that these seeds have a higher cellulose content compared with hemicellulose and lignin. Further, it was confirmed from the Van Krevelen diagram, CHO index, as well as devolatilization index. Also, from the kinetic analysis, the activation energy (E_a) obtained of these seeds was in the order of PR > AL > CF. The chemical features and thermal degradation behaviour reaffirmed that these non-edible oilseeds have good energy potential for reproducibility of biofuel and green chemicals production.

证明木质纤维素生物质转化为可再生燃料和有价值的化学物质的特性非常必要。在这项工作中，对一些非食用油种子的物理化学和热化学特性进行了描述，例如Putranjiva（Putranjiva roxburghii），Amaltas（Cassia fistula）和Siris（Albizia lebbeck））通过索氏溶剂萃取进行萃取分析，成分分析，近似分析，元素（CHNSO）分析，热值，堆积密度，XRD的结晶度指数，FTIR的官能团，EDX的矿物含量，EDG的结渣指数和结垢指数XRF，以及通过TGA进行的降解情况。值得注意的是，所有种子均包含最大比例的提取物，例如Putranjiva 50.55％，Amaltas 18.22％和Siris 22.8％。结果表明，与半纤维素和木质素相比，这些种子具有更高的纤维素含量。此外，由Van Krevelen图，CHO指数以及脱挥发分指数证实。同样，从动力学分析中，活化能（E _a这些种子获得的）的顺序为PR> AL> CF。化学特征和热降解行为再次证明，这些不可食用的油料种子具有良好的能源潜力，可再现生物燃料和绿色化学品的生产。
