Abstract

Devices and methods for the high-pressure treatment of bulk material by extraction and/or impregnation. The bulk material is arranged in the interior volume of a pressure vessel device and is treated at a high pressure while sealed off from the surroundings. The high-pressure treatment is performed batchwise in a closed system in the pressure vessel device in a pressure-tight fashion. The bulk material is fed batchwise to the interior volume with the pressure vessel device closed and being arranged on at least one treatment level and, after the high-pressure treatment has occurred, being discharged batchwise from the interior volume with the pressure vessel device closed. The invention furthermore relates to the use of a supporting tray module with at least one treatment level for the high-pressure treatment in a closed system.

First claim

1 .- 20 . (canceled)

21 . A method for the high-pressure treatment of bulk material by extraction and/or impregnation, comprising:
arranging the bulk material in an interior volume of a pressure vessel device; sealing the pressure vessel; applying a high pressure level in the range from 40 to 1000 bar to the bulk material; performing, batchwise, the high-pressure treatment in a closed system in the pressure vessel device by feeding the bulk material batchwise to the interior volume with the pressure vessel device closed and being arranged on at least one treatment level; and discharging, batchwise, the treated bulk material, after the high-pressure treatment has occurred, from the interior volume with the pressure vessel device closed; wherein the high-pressure treatment is performed using a supporting tray module which is arranged in the interior volume of the pressure vessel device and which has a multiplicity of treatment levels arranged one above the other in the interior volume, wherein the treatment levels are, for the high-pressure treatment and/or for the passage of the bulk material, mounted and positioned in displaceably actuatable fashion in the interior volume.

22 . The method of claim 21 wherein the batchwise feed of the bulk material comprises a feed of partial batches in each case to one of the treatment levels.

23 . The method of claim 21 wherein, during the batchwise feed and/or during the batchwise discharge, at least one of the treatment levels arranged in the interior volume is displaced for the passage of the bulk material; and/or wherein the batchwise feed and the batchwise discharge occurs unidirectionally in a single direction through the interior volume.

24 . The method of claim 23 wherein the batchwise discharge occurs downward in an axial gravitational force direction.

25 . The method of claim 21 wherein the batchwise feed and/or the batchwise discharge is performed at a pressure level between ambient pressure and high pressure level.

26 . The method of claim 21 wherein, during the batchwise feed and/or batchwise discharge, the bulk material quantity is detected.

27 . The method of claim 21 wherein the high-pressure treatment comprises at least an extraction and/or wherein the high-pressure treatment comprises at least an impregnation.

28 . The method of claim 21 wherein bulk material in the form of aerogels is subjected to high-pressure treatment by extraction and/or impregnation.

29 . The method of claim 21 wherein the high-pressure treatment comprises a fluidization of the bulk material.

30 . A control device configured to carry out the method of claim 21 wherein the control device is coupled to at least one sensor unit configured for detecting a throughflow of bulk material or a mass or a mass difference or a volume or a volume difference.

31 . A pressure vessel device configured for the high-pressure treatment, at a high pressure level in the range from 40 to 1000 bar, of bulk material by extraction and/or impregnation, comprising:
a cover; a high-pressure-resistant wall that encloses an interior volume; an inlet fitting coupled to the interior volume; and an outlet fitting, the inlet fitting and the outlet fitting respectively configured to permit the passage of the bulk material; a supporting tray module arranged in a suspended manner in the interior volume, the module having a multiplicity of actuatable treatment levels mounted and positioned in displaceably actuatable fashion, said treatment levels arranged one above the other, and which are configured in a substantially horizontally oriented plane in the interior volume and are configured to be loaded with bulk material in partial batches when the pressure vessel device is closed, and, after the high-pressure treatment has occurred at the high pressure level, unloadable in partial batches with the pressure vessel device closed, such that the high-pressure treatment is performed in a closed system which is sealed off with respect to the surroundings, and wherein the supporting tray module has at least one geometrically coupling intermediate element and multiple holding units for mechanical stability and support and a support unit for radial support in the lower region thereof.

32 . The pressure vessel device of claim 31 wherein the inlet fitting is configured to actuate in an automated fashion for the batchwise feed of the bulk material.

33 . The pressure vessel device of claim 31 wherein the at least one of the treatment levels is configured for the passage of bulk material and/or wherein at least one partial region of respective ones of the treatment levels is configured to displace from a corresponding high-pressure treatment position into at least one loading/unloading position.

34 . The pressure vessel device of claim 31 wherein at least one of the treatment levels is defined by at least one gas-permeable plate and/or wherein each respective of the treatment levels is defined by at least one pivotably actuatable gas-permeable plate.

35 . The pressure vessel device of claim 31 wherein each respective ones of the treatment levels is actuatable between at least two positions comprising a first position for the passage of bulk material and a second position for the accommodation and high-pressure treatment of bulk material.

36 . The pressure vessel device of claim 31 wherein the supporting tray module is integrated into the cover or is supported in the interior volume by means of the cover and/or wherein the inlet fitting for bulk material is integrated into the cover.

37 . The pressure vessel device of claim 31 wherein at least three treatment levels are provided.

38 . The pressure vessel device of claim 31 wherein each respective treatment level is displaceable by means of at least one rotationally actuatable actuating member.

39 . The pressure vessel device of claim 31 wherein each respective treatment level is displaceable by means of at least one translationally actuatable actuating member.

40 . The pressure vessel device of claim 31 wherein the supporting tray module comprises both at least one translationally actuatable actuating member and at least one rotationally actuatable actuating member.
