Embodiment 1

[0078] Utilize the above method, the present invention adopts following conditions to carry out experiment, current intensity: 0.3A; Reaction time is different; The volume concentration of the substance of NaCl: 0.4mol / L; The mass volume ratio of particle electrode and electrolyte: 2%; Mass volume ratio of lignin to electrolyte: 5%; sample was taken after reaction, extracted with ethyl acetate and n-hexane. Using GC-MS to analyze the types of products, the results of GC-MS showed that there were mainly two substances in the product, methyl palmitate and methyl octadecanoate. Since the product needs to be methylated before GC-MS, the actual product should be demethylated accordingly, so the main products of biomass conversion are palmitic acid and octadecanoic acid. The yield and conversion of each product were analyzed by GC-MS. The results of the gas phase detection chart are as follows: figure 1 Shown, product kind and transformation rate are as shown in table 1 and table ...

Embodiment 2

[0084] Utilize the above method, the present invention adopts following conditions to carry out experiment, electric current intensity: 0.3A; The amount concentration of the substance of NaCl: 0.2mol / L; Mass volume ratio: 5%; samples were taken after reacting for different times, and extracted with ethyl acetate and n-hexane. The yield and conversion rate of each product were analyzed by GC-MS, as shown in Table 3. The results of the gas phase detection chart are as follows: figure 2 shown.

Abstract

The invention discloses a method for converting biologic materials into soluble substances at one step. The method comprises the step that the biologic materials are electrolyzed for a certain time in the condition of a constant current by a bipolar three-dimensional electrode system, so that the biologic materials are converted into the soluble substances at one step, wherein the bipolar three-dimensional electrode system comprises an anode, a cathode, particle electrodes and an electrolyte, and during the electrolyzing process, the particle electrodes and the biologic materials are suspended in the electrolyte. The invention further discloses a container for converting the biologic materials into the soluble substances at one step. The container comprises a tank body, a pair of electrode plates and particle electrodes. The electrolyte is contained in the tank body. An opening is formed in one side wall of the tank body. A permeable membrane is arranged at the opening. The opening communicates with a discharge pipe. A part of the pair of electrode plates is soaked in the electrolyte, and a certain distance is formed between the pair of electrode plates. The pair of electrode plates is separately connected with the positive pole and the negative pole of a power supply. The particle electrodes are granular, and are suspended in the electrolyte. The invention further discloses a purpose of the soluble substances manufactured by the method.

Description

technical field [0001] The invention relates to a method for converting biomass materials into soluble substances in one step, a container for converting biomass materials into soluble substances in one step, and an application of the soluble substances converted from biomass materials. Background technique [0002] Biomass materials are the most abundant and cheapest renewable resource on earth. Use abundant biomass raw materials, such as agricultural waste (wheat straw, bagasse, corn straw), forestry waste (wood chips, branch wood, etc.) and marine algae (green algae, brown algae, red algae), etc., to produce fuel ethanol and Chemicals have become a research hotspot at home and abroad. The conversion of biomass into chemicals can meet the increasing energy demand of human society, reduce the dependence on increasingly scarce fossil fuels, and at the same time achieve the purpose of reducing pollution and protecting the environment. However, natural biomass materials are ...
