Biomass is widely considered as a raw material for the production of biochemicals and biofuels and among all the options for its use, the gasification process is the most popular due to its environmental advantages. The great arrival of sargassum to the coasts of the State of Quintana Roo, Mexico, which has taken place for several years, forces us to study its energy use. In this study, the experimental results of the gasification of four biomasses (pine sawdust, bamboo dust, rice husk, and cane bagasse) from three different bibliographical references were simulated and validated, using the Aspen Plus computer software. The simulation model used considers the combustion of 30% of the biomass and therefore an energy balance, in addition to an estimate of the tar generated in the process. Based on the comparison of the percentage molar composition and the heating value of the syngas obtained the performance of the process was evaluated, where the lowest error per difference was for the validation of rice husk (RH) with an ER of 0.35. Subsequently, the sargassum gasification simulation was carried out with information on the properties of this biomass from five bibliographic references, obtaining as a result a syngas with a lower heating value (LHV) that varies between 2.6 and 4.8 MJ/Nm for ER of 0.3 and 0.35, respectively.
生物质被广泛认为是生产生物化学品和生物燃料的原料，在其所有使用选项中，气化过程因其环境优势而最为流行。墨西哥金塔纳罗奥州海岸多年来一直大量出现马尾藻，这迫使我们研究其能源利用。在本研究中，使用Aspen Plus计算机软件对来自三个不同文献参考的四种生物质（松木锯末、竹粉、稻壳和甘蔗渣）的气化实验结果进行了模拟和验证。所使用的模拟模型考虑了30%生物质的燃烧，因此除了对过程中产生的焦油进行估计外，还进行了能量平衡计算。基于对所得合成气的摩尔组成百分比和热值的比较，对该过程的性能进行了评估，其中稻壳（RH）验证的每差值最低误差为0.35。随后，利用来自五个文献参考的关于这种生物质性质的信息进行了马尾藻气化模拟，结果得到了一种合成气，其低位热值（LHV）在当量比（ER）为0.3和0.35时分别在2.6至4.8 MJ/Nm之间变化。
