Abstract:
Method for setting in absorbed state, within on a porous support, compounds contained in a starting material, comprisinga. contacting, at supercritical pressure, the starting material with a solvent fluid comprising at least one solvent to obtain a mixture of extracts and solvent fluid; b. contacting the mixture of extracts and of solvent fluid with a bed of absorbent product adapted to absorb water selectively; c. adjusting the temperature and pressure conditions of the mixture of extracts and solvent fluid exiting from the absorbent bed to obtain a first phase consisting essentially of the solvent fluid in the gaseous state and a second phase comprising a mixture of solvent fluid and extracts from the starting material; d. contacting the first and second phases with a porous support adapted to absorb the extracts; e. vaporizing the solvent fluid contained in the second phase.
