Thermogravimetric curves are measured and modeled to quantify the changes induced by dilute acid or hot water washing on the devolatilization of short- and long-aged potato crop residues. The pretreatments cause more similar behaviors. A six-step devolatilization mechanism for four pseudo-components, previously developed for raw materials, is still applicable. The activation energies remain unvaried whereas small changes in the pre-exponential factors describe the displacement of the devolatilization process at higher temperatures. Instead, the nature and amounts of pseudo-components are significantly modified, especially for dilute acid washing and the short-aged sample. The pseudo-components pectin-hemicellulose and cellulose-starch are enriched in hemicellulose and cellulose, respectively. The corresponding total amounts of volatile generated increase from 19 up to 23–26wt% and from 19–26 up to 37–45wt%, in the same order. The volatile product yields released from the pseudo-component lignin-protein are practically unaltered, but lignin is likely to become largely predominant.

短期和长期粮食作物残留物洗涤预处理引起的脱挥动力学变化

对热重曲线进行测量和建模，以量化稀酸或热水洗涤对短期和长期马铃薯作物残留物脱挥发分引起的变化。预处理会导致更多类似的行为。之前为原料开发的四种拟组分的六步脱挥机制仍然适用。活化能保持不变，而指前因子的微小变化描述了较高温度下脱挥发分过程的位移。相反，假组分的性质和数量发生了显着改变，特别是对于稀酸洗涤和短期老化的样品。假成分果胶半纤维素和纤维素淀粉分别富含半纤维素和纤维素。相应产生的挥发物总量从 19 增加到 23-26wt%，从 19-26 增加到 37-45wt%，顺序相同。从假组分木质素-蛋白质中释放的挥发性产物产量实际上没有改变，但木质素很可能成为主要成分。
