Two-stage biomass hydrothermal catalytic activation reaction device

Abstract

The invention discloses a two-stage biomass hydrothermal catalytic activation reaction device and belongs to the field of a biomass hydrothermal technology. The device comprises a biomass high-pressure reaction kettle reactor and a vertical type activation furnace reactor which are communicated with each other through a packing auger drying bed; the biomass high-pressure reaction kettle reactor comprises a hydrothermal reaction cylinder, an additive loading tank and a biomass feeding pipe; under the condition of a carbon dioxide aqueous solution, the additive reacts with hydrogen ions in the aqueous solution to generate metal cations, so that biomass thermal decomposition is catalyzed to generate a high-quality liquid product; the biomass high-pressure reaction kettle reactor is also used for performing initial activation on hydrothermal coke; the vertical type activation furnace reactor comprises an activation reaction cylinder, a high-temperature activation gas nozzle, a round drainage plate and a ring-shaped drainage plate, and is used for preparing super activated carbon from the hydrothermal coke. The device is clever in design, can prepare supercapacitor electrode carbon and high-quality liquid products simultaneously by utilizing two-stage biomass hydrothermal catalytic activation reaction, and is high in energy utilization rate and high in production efficiency.

Description

technical field [0001] The invention belongs to the field of biomass hydrothermal technology, and in particular relates to a device for hydrothermal catalytic activation reaction of biomass. Background technique [0002] Biomass energy accounts for about 16% of the world's energy consumption, and it is the only renewable energy that can be converted into liquid fuel, which has huge utilization potential. The biomass resources available for exploitation in my country are extremely rich, and the annual output is equivalent to 656 million tons of standard coal. The efficient and high-quality conversion of biomass energy into high value-added products is an important development direction for the utilization of biomass resources in the future. Biomass hydrothermal is a process in which biomass and water are mixed in a certain proportion in a high-pressure reactor at a certain temperature and pressure, and then react to produce gas-liquid-solid three-state products. Biomass hyd...
