Abstract

Supercritical water (SCW) has emerged as an environmentally friendly reaction medium for efficiently transforming organic substances. Two key processes utilizing SCW are supercritical water gasification (SCWG) and supercritical water oxidation (SCWO), which offer efficient conversion of organic materials into useful gaseous products and harmless byproducts, respectively. SCWG involves the transforming organic substances into combustible gaseous products, which can be utilized for energy generation. Conversely, SCWO focuses on the oxidation of organic compounds, leading to the formation of innocuous byproducts. Both SCWG and SCWO processes can incorporate catalysts to enhance reaction efficiency and selectivity. The environment in a SCW process can vary based on the application or process stage, showing properties like reducing, oxidizing, nonionic, basic, acidic, or highly ionic. Modeling and simulation are crucial for understanding and optimizing SCWG and SCWO processes, guiding the design of efficient reactors for sustainable waste treatment and energy conversion.

揭开超临界水气化和氧化的魔力：可持续能源生产和废物管理的模拟和建模进展

超临界水（SCW）作为一种高效转化有机物的环境友好型反应介质而出现。超临界水气化（SCWG）和超临界水氧化（SCWO）是利用超临界水的两个关键工艺，它们分别将有机材料有效地转化为有用的气态产物和无害的副产物。SCWG涉及将有机物质转化为可燃气体产品，可用于发电。相反，SCWO侧重于有机化合物的氧化，导致无害副产物的形成。SCWG和SCWO工艺都可以加入催化剂来提高反应效率和选择性。SCW过程中的环境可以根据应用或过程阶段而变化，表现出还原性、氧化性、非离子性、碱性、酸性或高离子性等特性。建模和仿真对于理解和优化SCWG和SCWO过程，指导高效反应器的设计以实现可持续的废物处理和能量转换至关重要。
