Burning down on semi-solid by-product from distillation of cellulosic ethanol to power upstream steps of its manufacturing is usual. However, this feedstock is homogenous in size and shape, hygroscopic and poorly energetic. These disadvantages make its re-use in the industrial plant very complex. Conversion of this agro-residue into high-performance blends for heating and power is, accordingly, the scientific point of this study. The pilot-scale manufacturing of composite pellets consisted of systematically pressing the residue with sugarcane bagasse at the mass ratios of 1:4, 2:4, and 3:4 on an automatic pelletizer machine at 200 MPa and 125 °C. The process of compaction lasted for 90 s. Durability and energy density, both increased significantly, from 95.85% to 99.55% and from 27.95 GJ m⁻³ to 32.20 GJ m⁻³ with blending at 3:4. Practically, the semi-solid by-product considerably improved the feeding, thus, enabling the layers of particles to go smoothly through the channel-forming die of the machine. Thereby, blends became stiffer and denser than pellets purely consisting of sugarcane bagasse. Preliminary evidence of the process of pelleting capable of highly valorizing the semi-solid by-product from distillation of cellulosic bioethanol into mechanically stable and energetically effective hybrid fuel grade biosolids exist. The major findings of this paper should be of great relevance to ensure safe and effective transportation and storage of biomass in indoor facilities where the risk for the generation of dust and fines and the subsequent off-gassing and self-firing is high. Furthermore, pelletization may optimize the co-generation of heat and steam at the large-scale bioethanol station.

通常会燃烧掉纤维素乙醇蒸馏产生的半固体副产物，以推动其制造的上游步骤。但是，这种原料的大小和形状均一，吸湿性和能量不足。这些缺点使其在工业工厂中的重复使用变得非常复杂。因此，将这种农业残留物转化为用于加热和发电的高性能混合物是本研究的科学重点。复合颗粒的中试规模生产包括在200 MPa和125°C的自动造粒机上，用甘蔗渣以1：4、2：4和3：4的质量比对残渣进行系统压榨。压实过程持续了90 s。耐用性和能量密度均显着提高，从95.85％增至99.55％，从27.95 GJ m ^-3 增至32.20 GJ m⁻³以3：4混合。实际上，半固体副产物显着改善了进料，因此使颗粒层能够顺利通过机器的通道成型模具。因此，掺混物变得比纯粹由甘蔗渣组成的颗粒更硬，更密。存在制粒过程的初步证据，该制粒过程能够高度价值化地将纤维素生物乙醇蒸馏成机械上稳定且能量有效的混合燃料级生物固体中的半固体副产物增值。本文的主要发现应与确保室内设施中安全有效地运输和存储生物质具有重大意义，在室内设施中，产生粉尘和细屑以及随后的除气和自燃的风险很高。此外，
