绿色超临界流体的应用研究

Application research of green supercritical fluid

超临界流体具有与气体相似的密度、粘度、扩散系数等特性 ,应用领域日益广泛 ,主要有 :萃取、催化反应、结晶、吸附、材料制备、环境保护、食品工业、医药工业、染色工业、色谱分析、生物工程等。论述了超临界流体在这些领域的最新研究成果 ,重点介绍超临界流体在环境保护、染色工业、吸附过程、陶瓷脱脂。

Supercritical fluids have many special properties of density, viscosity and diffusion coefficient, which is similar with gas. Supercritical fluids being used more and more fields, for example, extraction, catalysis reaction, crystallization, adsorption, material preparation, environmental protection, foodstuff industry, medication industry, dying process, chromatogram analysis and biology technology.The newest development of supercritical fluid in the above aspects are discussed in this paper, specially illustrated the application of supercritical fluid in environmental protection, dying process, adsorption , degreasing the porcelain and preparing material.
