Supercritical carbon dioxide

The use of supercritical carbon dioxide can convert fossil fuels such as coal or natural gas into natural gas or fuel oil, realizing the improvement of monetary value and the protection of the environment. Supercritical carbon dioxide can replace organic solvents for the processing and manufacture of materials such as metals and plastics, effectively improving production efficiency and material quality. Supercritical carbon dioxide can be used as a clean and effective production tool, which can be used in the extraction, purification and crystallization of drugs to improve the purity and quality of drugs.


It can be used to prepare food ingredients such as plant alcohols, and can also be used to extract fats, spices and other ingredients in food to maintain the nutritional raw materials of food. It can replace solvents and other chemicals and can be used as a clean and effective treatment method to treat hazardous waste and reduce exhaust emissions. In short, it has the prospect of wide application and will play an important role in related fields. Supercritical carbon dioxide is a new type of medium with many advantages, such as green environmental protection, effective energy saving, wide application and so on. This article will introduce the advantages of supercritical carbon dioxide in detail, hoping that readers can better understand and understand this medium, and provide more ideas and possibilities for future development.


As an environmentally friendly medium, it will not produce harmful waste gas and wastewater, will not increase atmospheric and water pollution, and is in line with the concept and requirements of sustainable development. This is a non-negligible advantage for the increasingly environmentally conscious modern society, and it is also the fundamental social value of developing and utilizing supercritical carbon dioxide. Supercritical carbon dioxide has a high diffusion coefficient, permeability coefficient and solubility, which makes it more economical in raw materials and energy consumption than traditional media in many fields such as chemical, petroleum, and food. This is an important manifestation of the technical and economic superiority of supercritical carbon dioxide. It can play a rich and wide range of application values in the preparation of nanoparticles, the extraction of natural products, the preparation of polymer materials, and the preparation of metals and semiconductors. Industrial applications in many different industries also reflect the characteristics of supercritical carbon dioxide.


The physical and chemical properties of supercritical carbon dioxide can be adjusted in a wide range under temperature and pressure, so as to achieve fine reaction control, cost-effective production, and provide a better means for production optimization and improve product quality. As a natural non-volatile gas, when used under high temperature and high pressure conditions, the safety is greatly improved, and it will not cause fire and explosion during operation, and the safety of the human body and the environment is relatively high. As a pure medium, it can avoid the problems of oxidation and heterogeneous reactions common in traditional chemical processes, and it is also obviously helpful to improve the quality of products. This is of great significance to enhance the added value of products and improve the competitiveness of product markets. As a new, green and effective medium, its advantages in environmental protection, energy saving, wide applicability, controllability, safety and quality stability make it have a wide range of application prospects and important value in the fields of continuous development of technology, industry and production. We should pay more attention to and attach more importance to the research and application of this medium, and make due contributions to promoting sustainable development and the construction of responsible chemicals.
