摘 要: 超临界流体具有黏度低、密度大,有较好的流动、传质、传热和溶解性能等特性。超临界流体对状态参数的改变十分敏感,温度和压力较小的变化就会使流体的性质发生较大的改变。超临界流体已广泛应用于食品工业、医药工业、日用化工、石油化工、农药、林产工业、烟草工业、环境保护等领域。详细介绍了超临界流体在化学反应、涂料工业、超细材料制备、材料加工、建筑材料、超滤、皮革工业等方面的应用。 The supercritical fluid has the following unique characteristics: low viscosity, high density, better performance of flow, mass and heat transfer, dissolution and so on. The supercritical fluid is very sensitive to alternation of state parameter. The bigger change of fluid nature is caused by the smaller change of temperature and pressure. The supercritical fluid has been used in the food industry, medical industry, detergent & cosmetic, petrochemical industry, pesticide, forest industry, tobacco industry, environmental protection and so on. The applications of supercritical fluid in chemical reaction, coating industry, preparation of superfine material, material processing, building material, ultrafiltration and leather industry are introduced in detail.
