Nowadays, research has focused more on the behavior of the thermodecomposition of new lignocellulosic materials to improve scientific understanding of biomass as an energy resource. The present work focused on determining the thermogravimetric characteristics and kinetic modeling of Piptocoma discolor pyrolysis and combustion processes as a contribution towards understanding its energetic use in the Ecuadorian Amazon region. Thermogravimetric analysis was applied to study the thermal decomposition of P. discolor biomass under inert atmosphere conditions and in the presence of oxygen at a heating rate of 5 °C/min, from room temperature up to 900 °C. A mechanism of three independent parallel reactions was employed to detail the pyrolysis, as well as an additional step to model the combustion process in order to include the char oxidation reaction. The model succeeded in reproducing the degradation curves for pyrolysis and combustion with a very good fit between the experimental and calculated data. We obtained variation coefficient values of less than 5% (pyrolysis 3.19% and combustion 2.97%). Based on these results, it is confirmed that biomass obtained from P. discolor can be used as a source for energy generation using thermoconversion processes. The thermogravimetric and kinetic parameters provide useful information for designing a technically, economically, and environmentally feasible system for the energetic use of the biomass from P. discolor as a renewable resource in the Pastaza province of the Ecuadorian Amazon region.

如今，研究更多地集中在新型木质纤维素材料的热分解行为上，以提高对生物质作为能源资源的科学认识。目前的工作重点是确定Piptocoma 变色热解和燃烧过程的热重特性和动力学模型，以帮助了解其在厄瓜多尔亚马逊地区的能源用途。应用热重分析研究褪色假单胞菌的热分解生物质在惰性气氛和氧气存在下以 5 °C/min 的加热速率从室温升至 900 °C。采用三个独立平行反应的机制来详细说明热解，以及模拟燃烧过程的附加步骤，以包括焦炭氧化反应。该模型成功地再现了热解和燃烧的降解曲线，实验数据和计算数据非常吻合。我们得到的变异系数值小于 5%（热解 3.19%，燃烧 2.97%）。基于这些结果，证实了从P. discolor获得的生物质可用作使用热转换过程产生能量的来源。热重和动力学参数为设计一个技术上、经济上和环境上可行的系统提供了有用的信息，用于在厄瓜多尔亚马逊地区的帕斯塔萨省大力使用来自P. discolor的生物质作为可再生资源。
