Abstract

The invention relates to the field of cellulosic ethanol preparation and particularly relates to an electrochemical pretreatment device used for corn straw. The device includes a cathode, an anode, anelectrolyte and an electrolysis tank, wherein the cathode is foamed nickel or a nickel-containing binary or ternary alloy, the anode is a DSA anode, and the electrolyte is an acidic, neutral or alkaline inorganic solution. The device is advantages in that the device is simple in structure and convenient to operate and can be used at room temperature and atmospheric pressure; high energy consumption, and unsafe factors caused by high temperature and high pressure are avoided; a product is pure and no pollutant is introduced.

Description

technical field [0001] The invention relates to the field of cellulosic ethanol production, in particular to an electrochemical pretreatment device for corn stalks. Background technique [0002] Energy and environmental issues are issues that must be resolved to achieve sustainable development. In the long run, the shortage of liquid fuel will be a big problem that plagues human development. Against this background, biomass is gaining increasing attention as the only renewable resource that can be converted into liquid fuels. Therefore, the technology of biomass liquid fuel has great development prospects, among which the technology of biomass fuel ethanol has attracted the most attention. Existing industrialized fuel ethanol production uses sugar or grain as raw material. The advantage is that the process is mature, but the output is limited by the raw material, so it is difficult to meet the energy demand for a long time. [0003] In the long run, the production of fuel...
