TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The first, the second and the third line systems are provided with several controllable two-way valves and three-way valves, which are connected with a program controller (10) of the device, so that the filling, circulation and discharging of the three reactors are adjustable. The first area comprises several receiving- and storing points for providing a single variety of different types of biomass, and at least one crushing unit and a mixer for the different types of biomass. The second area comprises a mixing container, in which the first line with the mixed biomass of the first area, the second line for processing water, and the third line, which is supplied with the catalyst extracted from a tank, are emptied, where the processing water and the catalyst are mixed in a mixer, and an additional stirrer operated with a motor is provided in the mixing container. The third line is provided with a pump, through which the provided and mixed biomass with the processing water and the catalyst are supplied for carrying out the reaction process. The fourth area comprises a collecting container for receiving the reaction products from the activated reactor, in which the reaction process is completed, where the collecting container exhibits an additional stirrer operated with a motor, which is connected with the dewatering device and the downstream dryer via the first line provided with the pump. The second line of the dewatering device is provided with a collecting container for the processing water, which is supplied to the second area via the second line provided with the pump, and the reaction products are supplied from the dryer to the collecting container for the removal. A fifth area is provided, where at least a portion of the reaction products is supplied from the activated reactor after the completion of the reaction process, and the reaction products are converted into a synthesis gas in the fifth area. The fifth area is connected with a carbon source for producing the synthesis gas. The several controllable two-way valves and the three-way valves are provided in the first, the second, the third, the fourth and the fifth areas, where a material flow is regulated within the device via the program controller. The program controller is provided in the device, through which the two-way valves, the three-way valves and the pumps are controlled in the first, the second, the third, the fourth and the fifth areas, and thus the material flow is regulated within the device via the program controller.
