The depletion of fossil fuels has fueled an increased interest in biomass resources usage for heat and electricity generation. As an important biomass resource, Chinese medicine residues have great potential in substituting fossil fuels. However, that is basically limited by its poor properties, including low bulk density, high moisture content, and inhomogeneous structure. Herein, a safe and sustainable strategy was reported to prepare a high-quality densified pellet derived from Chinese medicine residues to address these worries. In this process, mixed and simple size materials were densified under various moisture content and pressure using a laboratory electronic tablet press machine equipped a single pellet mold. Results showed that higher pressure, ideal moisture content (∼6.5 %), and mixed particle size could densify better quality pellets. These findings pave the way for the safely and efficient resource utilization of Chinese medicine residues, as well as providing theoretical guidance and technical support for the household heating.
化石燃料的枯竭激发了人们对将生物质资源用于供热和发电的兴趣。作为一种重要的生物质资源，中药残渣在替代化石燃料方面具有巨大潜力。然而，这基本上受到其不良特性的限制，包括堆积密度低、水分含量高和结构不均匀。在此，报道了一种安全且可持续的策略，以制备源自中药残渣的高质量致密颗粒，以解决这些问题。在此过程中，使用配备单个颗粒模具的实验室电子压片机，在不同水分含量和压力下对混合和单一尺寸的材料进行致密化处理。结果表明，较高的压力、理想的水分含量（约6.5%）和混合粒径可以致密化出质量更好的颗粒。这些发现为中药残渣的安全高效资源利用铺平了道路，也为家庭供暖提供了理论指导和技术支持。
