摘要

超临界水热合成是一种环保、高效的纳米材料合成方法。中国首个纳米银纳米颗粒（AgNPs） SCHS中试工厂已成功建成，通过反应器和系统优化，生产出粒径可控的AgNPs。本文系统地探讨了加热和混合效率低以及堵塞的挑战，并提出了有针对性的解决方案，包括高效加热，热量再利用和混合器结构优化。客观描述了系统的详细组成、显著性能、先进的控制方法和中试装置的初步实验结果，获得了平均粒径为36.1 nm的高纯AgNPs。这些发现将有助于SCHS中试工厂连续批量生产纳米颗粒的商业化。

Design of China first pilot plant for supercritical hydrothermal synthesis of AgNPs

Supercritical hydrothermal synthesis (SCHS) is an eco-friendly and efficient method for synthesizing nanomaterials. China's first pilot plant for SCHS of silver nanoparticles (AgNPs) has been successfully built, producing AgNPs with controllable particle sizes through reactor and system optimizations. This manuscript systematically explores the challenges of low heating and mixing efficiency and clogging, and proposes targeted solutions, including efficient warming, heat reuse and mixer structure optimisation. The detailed system components, evident properties, advanced control methods and primary experiment results of the pilot scale plant are described objectively, achieving high-purity AgNPs with an average particle size of 36.1 nm. These findings will contribute to the commercialisation of the SCHS pilot plant for continuous batch production of nanoparticles.

期刊介绍： ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering. Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
