Abstract: The present disclosure relates to a system and method for pumping a feedstock slurry through a device. The system includes a pressure pump, a first sensor, a second sensor, a controller, and a control valve. The pressure pump includes a plunger configured to pressurize the slurry to a first pressure prior to the slurry entering the device. The first sensor is configured to sense a second pressure of the slurry entering the device. The second sensor is configured to sense the position of the plunger. The controller is configured to determine a change of position of the plunger based on the sensed position of the plunger and to control the movement of the plunger by setting a plunger mode based on the second pressure of the slurry and the change of position of the plunger. The control valve is configured to control the flow rate of the slurry through the device.

Abstract: The invention concern methods for converting carbonaceous feedstock slurry into synthetic fuel gas comprising: (a) introducing a carbonaceous feed stock slurry into a first reaction vessel via a continuous feed; (b) converting said carbonaceous feed stock slurry to a carbon char slurry comprising carbon char, and water by allowing said carbonaceous feed stock slurry to have a residency time of between 5 and 30 minutes in said first reaction vessel, said carbonaceous feed stock slurry being heated to a temperature of between about 260 to about 320° C. at a pressure such that water does not flash to steam.

Abstract: A system and method for devolatilizing a carbonaceous feedstock are provided. The system includes a devolatilization reactor having a unit shell, at least one tube bundle, a pump, and a control valve. The unit shell is configured to allow a heating fluid to flow within. The at least one tube bundle is configured to allow the feedstock to flow within the tube bundle and further configured to be positioned at least partially within the unit shell. The tube bundle comprises at least one tube and at least one tube bend. The at least one tube bend is disposed external to the unit shell. The pump is configured to pump the feedstock into the at least one tube bundle. The control valve is configured to control the flow rate of feedstock into the at least one tube bundle.

Abstract: A system for gasifying a carbonaceous feedstock, such as municipal waste, to generate power includes a devolatilization reactor that creates char from the feedstock and a gasifier that creates a product gas from both the char and from volatiles released when devolatilizing the feedstock. The product gas is reacted in a fuel cell to create electrical energy and process heat. The process heat is used to heat the devolatilization reactor and the gasifier. The gasifier comprises a plurality of configurable circuits that can each be tuned to meet the individual needs of the char material being gasified.
