Description
Technical Field
The application relates to the technical field of biomass energy utilization, in particular to a biomass pyrolysis steam intermediate-temperature electrochemical upgrading process.
Background
Bio-oil is the pyrolysis product of biomass and is the only carbon-containing renewable energy source present in liquid form. Compared with biomass, bio-oil has a high energy density, which is typically up to 10 times the energy density of biomass. The conversion of biomass into bio-oil is a promising low-cost utilization of biomass energy. However, bio-oils currently have no mature industrially applicable or processing technology. The fundamental reason for the difficulty in handling and applying bio-oil is its characteristic physicochemical properties. Bio-oil components are complex (including acids, phenols, alcohols, ketones, and carbohydrates), high in acid value, high in viscosity, and corrosive, making it difficult to transport and store on a large scale. Bio-oils are high in oxygen content (40-50 wt.%), low in calorific value (14-19 MJ/kg), resulting in difficulties in direct application to combustion equipment. Therefore, bio-oils must be refined and upgraded to improve fuel properties or to refine high value added chemicals. At present, the upgrading method of the bio-oil is mainly based on traditional methods such as thermochemical hydrodeoxygenation, catalytic cracking, steam reforming and the like, and the treatment process needs to be carried out in a high-temperature or high-pressure environment. However, the bio-oil has poor thermal stability, is easily coked by heating to form carbon deposition, causes reactor blockage or catalyst inactivation and has long reaction residence time, reduces the upgrading efficiency, and even causes difficult reaction. In addition, the researchers propose that the bio-oil is upgraded by adopting a low-temperature electrolytic cell, the low-temperature electrolytic cell is used for upgrading the liquid bio-oil at the working temperature lower than 100 ℃, and the problems of high energy consumption, incapability of continuous treatment, electrode corrosion and the like exist.
The patent application with publication number CN 104560102A discloses a method for improving quality of bio-oil, which comprises adding bio-oil generated by cracking into a high-pressure kettle, adding calcium oxide, reacting at 30-80 deg.C for 1-4 hr under nitrogen protection, heating to 160-180 deg.C for 0.5-2 hr, cooling to 80-120 deg.C, and keeping the temperatureReacting for 0.5-2 hours to obtain C 7 -C 15 A paraffin-like fuel precursor. The method can well reduce the acid content in the biological oil and improve the pH value and stability of the biological oil. However, the method mainly aims at the quality improvement of acid substances in the bio-oil, has no obvious quality improvement effect on other components in the bio-oil, does not improve the problems of high oxygen content, low heat value and the like of the bio-oil, has limited quality improvement effect, can not realize the continuous treatment of the bio-oil, and has no wide application value.
The patent application with publication number CN 102851062A discloses a process for catalytic hydrogenation of bio-oil promoted by organic solvent, which comprises placing a certain amount of organic solvent and catalyst into a continuous reactor, replacing air in the reaction system with hydrogen, stirring under 10-12MPa hydrogen pressure, heating to 280-320 deg.C, reacting for 2-4h, and supplementing new hydrogen with hydrogen-oil ratio of 1000-2000 during the reaction process. The method promotes the catalytic hydrogenation reaction of the bio-oil through the organic solvent, and solves the problem that the bio-oil is easy to polymerize and coke in the catalytic hydrogenation process. However, the method adopts hydrogen as a hydrogen atom source, has high cost, low hydrogen atom utilization rate and poor economy, and simultaneously, the reaction is carried out under high pressure, so that the requirement on the performance of equipment is high, the operation cost is increased, and the wide industrial application is greatly limited.
Patent applications with publication numbers CN 111909736A and CN 113717746A respectively disclose a bio-oil electrochemical upgrading method and a bio-oil hydrodeoxygenation method, wherein the two methods both use an H-type electrolytic tank to carry out bio-oil electrochemical upgrading, the former uses mixed liquid of bio-oil, an organic solvent and a supporting electrolyte as catholyte, an acid solution as anolyte, the anolyte and the catholyte are separated by an ion exchange membrane and react for 2-8H under the current of 50-200mA to realize the electrochemical upgrading of bio-oil; the latter uses platinum net as anode, carbon paper as cathode and carries Pt/CeO 2 a/C catalyst. The two methods can reduce the content of biological oleic acid, aromatic components and heavy components, and simultaneously avoid the generation of carbon deposition in the quality improvement process. But will cause the corrosion of the electrode due to the acidity and corrosiveness of the bio-oil, and in addition, the low-temperature electrolysisThe working temperature of the pool is lower than 100 ℃, the quality improvement can only be carried out on the liquid bio-oil, the on-line continuous quality improvement can not be realized, the energy consumption is high, and the industrial application value is greatly limited.
Accordingly, there is a need for an upgrading process for upgrading bio-oil in biomass pyrolysis steam.
