Abstract

An apparatus for forming a water storage material from a biomass input material using supercritical or subcritical fluid processing, the water storage material capable of absorbing a liquid and releasing the liquid. The apparatus utilizes supercritical fluid processing, subcritical fluid processing, charring, or a combination thereof. The apparatus includes a controller configured to control the apparatus. The apparatus further including a processing station configured to hold the biomass input material, and to use the biomass input material for processing into the water storage material.

Claims

1. An apparatus for forming a water storage material from a biomass input material using supercritical or subcritical fluid processing, the water storage material capable of absorbing a liquid and releasing the liquid, comprising:

a controller configured to control the apparatus;

a processing station, the processing station configured to hold the biomass input material, and to use the biomass input material for processing into the water storage material;

a storage unit configured to hold a fluid;

a liquid outlet, the liquid outlet having a fluid input connected to an output of the storage unit, the liquid outlet positioned to supply the fluid into the processing station for processing the biomass input material into the water storage material;

a pump; and

a basin, the basin configured to receive the fluid supplied by the liquid outlet, the basin positioned such that the fluid supplied by the liquid outlet passes through the processing station before being received in the basin, the basin operatively connected to an input of the storage unit such that fluid captured in the basin is returned to the storage unit.

2. The apparatus of claim 1, further comprising a sensor configured to detect a status of the biomass input material during processing, wherein the sensor further configured to provide a signal indicative of the status of the biomass input material to the controller.

3. The apparatus of claim 1, further comprising a filter, the filter having a filter input and a filter output, the filter input receiving the fluid received by the basin, wherein the fluid passes through the filter and out the filter output, wherein the fluid is routed to the storage unit.

4. The apparatus of claim 1, further comprising a heating element operative to heat fluid inside of the storage unit.

5. The apparatus of claim 4, wherein the heating element is powered by electricity.

6. The apparatus of claim 4, wherein the heating element is powered by combustion of a fuel.

7. The apparatus of claim 6, wherein the fuel is a material of the same composition as the biomass input material.

8. The apparatus of claim 4, wherein the processing station comprises a conveyor.

9. The apparatus of claim 4, wherein the fluid is acidic.

10. The apparatus of claim 4, wherein the controller is operable to control a fluid pressure, a fluid temperature, and an input material processing time.

11. An apparatus for forming a water storage material capable of absorbing a liquid and releasing the liquid, comprising:

a processing station configured to hold a biomass input material, and to use the biomass input material for processing into the water storage material;

a storage unit configured to hold a fluid;

a liquid outlet having a fluid input connected to an output of the storage unit, wherein the liquid outlet is positioned to supply the fluid into the processing station for processing the biomass input material into the water storage material; and

a basin configured to receive the fluid supplied by the liquid outlet, wherein the basin is positioned such that the fluid supplied by the liquid outlet passes through the processing station before being received in the basin, and wherein the basin is operatively connected to an input of the storage unit such that fluid captured in the basin is returned to the storage unit.

12. The apparatus of claim 11, further comprising:

a controller; and

a sensor operatively coupled to the controller, the sensor configured to;

detect a status of the biomass input material during processing; and

provide a signal indicative of the status of the biomass input material to the controller.

13. The apparatus of claim 12, wherein the controller is programmed to control a fluid pressure, a fluid temperature, and an input material processing time in response to the signal.

14. The apparatus of claim 11, further comprising a filter, the filter having a filter input and a filter output, the filter input receiving the fluid received by the basin, wherein the fluid passes through the filter and out the filter output, wherein the fluid is routed to the storage unit.

15. The apparatus of claim 11, further comprising a heating element operative to heat fluid inside of the storage unit.

16. The apparatus of claim 15, wherein the heating element is powered by one of electricity or combustion of a fuel.

17. The apparatus of claim 16, wherein the fuel is a material of the same composition as the biomass input material.

18. The apparatus of claim 11, further comprising a pump configured to transport the fluid to the liquid outlet.

19. The apparatus of claim 11, wherein the processing station comprises a conveyor.

20. An apparatus for forming a water storage material from a biomass input material, the water storage material capable of absorbing a liquid and releasing the liquid, comprising:

a controller;

a processing station configured to hold the biomass input material, and to use the biomass input material for processing into the water storage material;

a sensor operatively coupled to the controller and configured to;

detect a status of the biomass input material during processing, and

provide a signal indicative of the status of the biomass input material to the controller;

a storage unit configured to hold a fluid;

a liquid outlet having a fluid input connected to an output of the storage unit, wherein the liquid outlet is positioned to supply the fluid into the processing station for processing the biomass input material into the water storage material;

a pump configured to transport the fluid to the liquid outlet; and

a basin configured to receive the fluid supplied by the liquid outlet, wherein the basin is positioned such that the fluid supplied by the liquid outlet passes through the processing station before being received in the basin, and wherein the basin is operatively connected to an input of the storage unit such that fluid captured in the basin is returned to the storage unit.
