Since 1869, Thomas Andrews discovered the existence of the critical point, and it has been more than 100 years, but the development of supercritical fluid technology has been relatively slow. The potential application prospects have been able to develop rapidly.
Supercritical water oxidation technology uses water as the medium and uses the absence of mass transfer resistance at the gas-liquid interface under supercritical conditions (temperature>374 ℃, P>22.1 MPa) to increase the reaction rate and achieve complete oxidation.
Aerogel is a porous nanomaterial with high specific surface area and low bulk density. Due to the unique nanostructure of aerogel, it has broad application prospects in aerospace, catalysis, environmental protection and other fields.
Supercritical fluid extraction (SFE) refers to the use of supercritical fluids that have high solubility for solutes in a supercritical state and low solubility for solutes in a non-supercritical state.
