Abstract
The features of the supercritical drying process are considered. The intensification methods of the supercritical drying for the production of aerogels were shown. The influence of the CO2 supply, process temperature and CO2 flowrate on the performance of supercritical drying was studied. The methods were proposed which permits to reduce the mass of used carbon dioxide in the one cycle of supercritical drying by 63.4%.
