Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to an iron-carbon material for recycling residue asphalt and a preparation method and application thereof.
Background
With the continuous development of society, the living standard of people is continuously improved, the sustainable development idea is generated, the economic development and the resource and ecological environment bearable capability are considered and coordinated, and the environmental pollution problem caused by the over-fast development is reduced or even eliminated. The main pollution at present relates to multiple levels such as water pollution, air pollution, noise pollution, nuclear radioactive pollution, heavy metal pollution and the like. The pollution of water resources is most closely related to people's life, if sewage sources such as industrial wastewater, livestock wastewater, pesticide wastewater, domestic garbage leachate and the like are directly discharged without being treated, the ecological environment is inevitably affected seriously, and finally, the water circulation system and the biological enrichment process cause great harm to the health of human bodies. How to treat sewage existing in various industries at low cost and effectively absorb or degrade pollutants becomes an important issue concerned by enterprises, governments and society. The micro-electrolysis method becomes a preferred scheme of a plurality of water treatment plants due to the characteristics of mature preparation process, low cost, low investment, recycling, simple operation condition and the like. The micro-electrolysis method starts in the seventies of the twentieth century, treats underground water by taking zero-valent iron as an electrode for the first time, and gradually develops into treatment of industrial wastewater in the eighties. The iron-carbon micro-electrolysis filler in the micro-electrolysis method is most widely used, carbon powder and scrap iron are used as raw materials to respectively form positive and negative electrodes of a micro-electrolysis primary battery, a plurality of micro-electrolysis primary battery systems are formed in a wastewater system by utilizing the potential difference of about 1.2V between the two electrodes, and the specific battery reaction is as follows,
and (3) anode reaction:
Fe - 2e - → Fe 2+ ， E θ (Fe 2+ /Fe)= - 0.44 V
the cathode reaction is different under different conditions,
under acidic conditions:
2 H + + 2 e - → 2 [H] → H 2 ，E θ H + / H 2 = 0 V
acid and setting aeration device:
O 2 + 4H + + 4e - → 2 O·+ 4 [H] → 2H 2 O，E θ O2/H2O = + 1.23 V
neutral, alkaline and set up aeration equipment:
O 2 + 2H 2 O + 4e - → 4OH - ，E θ O2/ OH - = + 0.40 V
based on the reduction process of zero-valent iron and the flocculation of ferric ions continuously generated in the electrolysis process of the primary battery, the method effectively degrades or adsorbs organic pollutants and heavy metal ions in a wastewater system. The reducibility of zero-valent iron can degrade organic macromolecules in the wastewater, the decolorizing groups of dye molecules are decomposed, and organic pollutants can be partially converted into CO under the aeration condition 2 、H 2 O to reduce the COD value, and the flocculation precipitation effect of ferric ions can remove heavy metal ions through adsorption chelation, thereby effectively realizing sewage purification. The iron-carbon microelectrolysis filler used by the microelectrolysis method is added with a binder and a catalyst component to improve the stability and the electrical degradation activity besides the iron filings and carbon powder used as electrodes, and the components are fully mixed, calcined and formed at high temperature and then subjected to sewage treatment.
CN201611153603 discloses a pulverized coal molding dry distillation method using waste as binder, which comprises mixing heavy coal tar pitch, tar residue, and polyaluminum ferric chloride, adding dolomite powder, and making into viscous paste to obtain binder. And then, carrying out cold press molding on the adhesive and pulverized coal to obtain molded coal, and pyrolyzing the molded coal in a retort at low temperature to obtain semi coke, coal tar and coal gas. The method provides raw material lump coal for producing semi-coke, effectively utilizes coal tar in tar residues, improves the oil yield of the molded coal, and realizes waste recycling. But the defects are that the tar pitch only plays a bonding role, and the catalytic component in the tar pitch is not fully utilized to play a catalytic role. CN201310012452 discloses a method for treating alpha naphthol wastewater by using iron-carbon micro-electrolysis and a catalyst, and the method mainly prepares a catalyst TiO 2 /γ-Al 2 O 3 Mixing and stirring ethyl titanate or n-butyl titanate, absolute ethyl alcohol, distilled water and hydrochloric acid to form uniform transparent light yellow sol, and taking a certain amount of gamma-Al 2 O 3 And (3) soaking the porous small ball carrier in the prepared light yellow sol, and then calcining for 2 hours in a muffle furnace to obtain the prepared catalyst. Under the irradiation of ultraviolet lamp, adding iron filings, active carbon and TiO 2 /γ-Al 2 O 3 After the catalyst treatment, 68.7 percent of COD in the alpha naphthol wastewater can be removed. The invention specially prepares the iron-carbon catalyst, and utilizes the ultraviolet lamp to carry out photocatalysis, but compared with other iron-carbon materials, the COD degradation rate is improved to a limited extent, and the preparation cost is higher.
In the coal chemical industry, a large amount of coal is directly combusted to generate a large amount of greenhouse gases and easily generate dioxin and NO x And the like, so the coal liquefaction becomes a main path for clean utilization of the coal. The process of directly converting coal into liquid fuel by hydrocracking under the action of hydrogen and catalyst is called direct coal liquefaction, and the process mainly adopts hydrogenation means, so that the process is also called a coal hydrogenation liquefaction method. After solid-liquid separation, the product of the direct coal liquefaction technology can generate about 30% of heavy byproducts which are called as direct coal liquefaction residues. About 45% of these liquefaction residues are unreacted coal, minerals, and catalysts used in the direct coal liquefaction process, about 30% of the heavy oil component, and about 25% of the asphaltic species. The heavy oil deep hydrogenation conversion process including heavy oil suspension bed hydrogenation also produces a large amount of sticky heavy asphalt components, the composition of the heavy asphalt components is similar to that of the coal direct liquefaction process, a large amount of iron catalysts or nickel, molybdenum and cobalt catalysts are remained, in addition, the coal and the heavy oil have certain sulfur content, sulfides can be used as cocatalysts for the coal direct liquefaction, and the coal direct liquefaction residue asphalt contains more catalyst components such as iron sulfide, molybdenum sulfide, nickel sulfide, vanadium sulfide and the like after the hydrogenation liquefaction. The residue obtained by direct coal liquefaction and deep heavy oil hydroconversion is similar to natural asphalt in composition and physical properties, and the current main application is limited to adding the residue into the natural asphalt to serve as modified asphalt, so that the performance of the road asphalt can be improved, and the price of the modified asphalt can be reduced.
The coal can be subjected to hydrogenation co-refining with heavy oil besides a direct liquefaction process, can promote the lightening of the heavy oil during coal liquefaction, and has good economical efficiency and industrial prospect. The core of coal-heavy oil co-refining and coal direct liquefaction is a catalyst, wherein the catalyst is mainly derived from coal direct liquefaction catalysts, namely iron, cobalt, molybdenum, nickel and tungsten catalysts. When the reaction is completed at high temperature and high pressure, the system also produces a certain amount of residual asphalt, which has high viscosity and contains a certain amount of waste catalyst with partial activity, such as iron sulfide, molybdenum sulfide, etc., and active non-hydrocarbon components such as sulfur, nitrogen, metals, etc. The viscosity of the residual asphalt mainly comes from the fact that the residual asphalt is rich in polycyclic aromatic hydrocarbons, colloid, asphaltene and other components, so that the difficulty of diluting and separating the waste catalyst from the system is huge, the cost is high, and the subsequent treatment and recovery of the residual asphalt are difficult. According to statistical calculation, the cost of the catalyst obtained by diluting and separating the effective components in the waste catalyst from the residual asphalt system is about three times higher than that of the newly prepared catalyst, and the subsequent treatment and reutilization of the residual asphalt are difficult to realize by an economic and reasonable means.
