THE METHOD OF EXTRACTION AND THE METHOD OF REALIZATION OF THE REACTION WITH USAGE OF THE SUPERCRITICAL FLUIDS Russian patent published in 2006 - IPC B01D11/02 

FIELD: chemical industry; methods of an extraction and realization of reactions with utilization of the supercritical fluids.

SUBSTANCE: the invention presents the method of removal of a miscible material from the various substrates, which may find application in the processes of extraction and at realization of the catalytic reactions. The method provides, that a substrate containing a miscible material is affected by a supercritical fluid, in which the indicated material practically is completely dissolved, and the substrate does not dissolve, and the pressure of the supercritical fluid is periodically modulated between two or several pressure levels, which are chosen so, that the relative difference between the maximal and minimal values of the density of the fluid at these pressure levels make no more than near 30 %. The method ensures an upgrade of efficiency of the extraction process, the raised rates of the catalytic reactions and preservation of the catalyst activity at the appropriate level.

EFFECT: the invention ensures an upgrade of efficiency of the extraction process, the raised rates of the catalytic reactions and preservation of the catalyst activity at the appropriate level.
