摘要:

热驱动的水热转化技术是一种典型的热化学反应工程技术。该技术可在治理有机废物的同时回收有价资源,是实现双碳目标的重要途经。本文以有机废物为对象,首先梳理了水热技术的整体发展脉络,介绍了水热转化技术在有机废物转化中的典型类别和特征,并阐述了亚临界水和超临界水的性质;随后回顾了水热转换设备的发展,强调了工程应用中的典型水热转化设备并分析了设备研发中需注意的潜在问题;分析了水热转化技术在有机废物治理和资源回收上的典型案例。最后对有机废物水热转化现存挑战作出分析,指出实际环境中复杂水质引发的设备腐蚀、特定产物所需高效催化剂的研制、过程污染物的产生和难以协调的技术经济可行性仍是该技术的制约条件。本文旨在为有机废物水热转化工程实践提供理论和技术参考。

Abstract:

Heat-driven hydrothermal conversion technology is a typical thermochemical reaction engineering technology, which can simultaneously achieve the organic waste treatment and resource recovery, providing a vital way to achieve the goal of carbon peaking and carbon reduction. Taking organic waste as the object, this study first combs the overall development of hydrothermal technology, introduces the typical categories and characteristics of hydrothermal conversion technology in organic waste conversion, and expounds the properties of subcritical water and supercritical water. Then, the development of hydrothermal conversion equipment is reviewed. The typical hydrothermal conversion equipment in engineering application is emphasized and the potential problems that need to be focused in equipment development are analyzed. The typical cases of hydrothermal conversion technology in organic waste treatment and resource recovery are dissected. Finally, the existing challenges of hydrothermal conversion of organic waste are discussed, and the equipment corrosion caused by complex water quality in the actual environment, the development of highly efficient catalysts for specific products, the production of process pollutants and the technical and economic feasibility are still the restrictive conditions of this technology. This paper aims to provide theoretical and technical reference for the engineering practice of hydrothermal conversion of organic waste.
