Device for liquefying biomass through cooperation of rotary tooth-shaped electrode discharge and heterogeneous catalyst

Abstract

The invention provides a device for liquefying biomass through cooperation of rotary tooth-shaped electrode discharge and heterogeneous catalyst, two same hollow tube electrodes are arranged, a plurality of triangular tooth sheets are fixed at the same position of the lower end of each electrode, a foam structure type catalyst is arranged above and below each triangular tooth sheet, the catalyst is composed of a carrier and an active component, and the carrier and the active component are mutually matched. And the catalyst is fixed on the hollow pipe. A sealing flange, an insulating cover and a sealing cover which are tightly connected are sequentially arranged above the reaction cavity from bottom to top, an air inlet is formed in the sealing cover, an air outlet is formed in the bottom of each hollow pipe, the upper end of each hollow pipe is connected with a motor fixedly arranged on the insulating cover, and the motor drives an electrode to rotate so as to increase disturbance and improve the heat and mass transfer capacity of a solvent. Meanwhile, ventilation is carried out at the tooth-shaped electrode, the discharge difficulty is reduced, and a foam structure type catalyst is arranged at the electrode, so that a plasma catalysis synergistic effect is generated, rapid and efficient biomass liquefaction is realized, and the quality of a liquefied product is improved.

Description

technical field [0001] The invention relates to a liquefying biomass device, in particular to a liquefying biomass device of a rotating tooth-shaped electrode discharging in cooperation with a heterogeneous catalyst. Background technique [0002] As the only renewable carbon-containing resource, biomass energy has unique advantages in terms of environment and economy. Environmentally, biomass energy is a renewable energy source, which can meet the requirements of carbon neutrality while meeting future social energy needs. Economically, biomass energy is rich in variety, large in reserves, low in cost of raw materials, and easy to obtain, which has great economic advantages. Biomass liquefaction is a process in which biomass raw materials are distributed in a liquid medium and converted into liquid products. Biomass liquefaction can adapt to the characteristics of low biomass energy density, high moisture content, difficult collection and transportation, and high distributio...
