Definitions
- the invention belongs to the technical field of preparation of inorganic substances, and specifically relates to a method for preparing high-purity cobalt nitrate crystals by using 0)/310 2 spent catalyst.
- Biomass is the most abundant and cheapest renewable resource on the planet.
- the annual amount of lignocellulosic biomass produced by photosynthesis in the world is as high as 150 billion tons, of which about 90% are not yet used by humans.
- the biomass is gasified into syngas, and then the synthetic oil is produced by Fischer-Tropsch synthesis reaction. After the subsequent processing, rectification and other post-treatment processes, the synthetic oil can obtain ultra-clean gasoline and diesel oil superior to the European V standard, and has wide application prospects. .
- the silica-supported cobalt-based Co/SiO 2 catalyst has high catalytic hydrogenation activity, the reaction rate is not affected by the water pressure, is not easy to deposit carbon and poison, and has low selectivity to form CO 2 , high selectivity of long-chain hydrocarbons, and products. It has less oxygen-containing compounds and is a better and most studied catalyst system in the Fischer-Tropsch synthesis reaction industry. China's cobalt resources are extremely scarce. The proven recoverable amount is less than 2% of the world's recoverable amount, while the annual use is close to 25% of the world's total consumption. Therefore, China's cobalt resources are heavily dependent on imports, and the price is high. Lead to higher catalyst costs.
- the recovery of cobalt from the waste catalyst for cobalt-based Fischer-Tropsch synthesis is used for the regeneration of cobalt-based catalysts, which not only reduces the environmental pollution of the spent catalyst, but also improves the utilization of cobalt resources, and greatly reduces the production cost of the cobalt catalyst. Environmental and economic benefits.
- Chinese Patent Application No. 200810055107.0 discloses a method for recovering cobalt in a cobalt-based Fischer-Tropsch synthesis catalyst, which comprises deionized water and a cobalt-containing Fischer-Tropsch catalyst (including Si0 2 , A1 2 0 3 , Zr0).
- Chinese patent No. 200910272794.6 discloses a kind of A method for preparing high-purity cobalt nitrate by using Fischer-Tropsch synthesis with alumina-supported cobalt-based spent catalyst, the method comprising the steps of milling, concentrated hydrochloric acid dissolution, sodium sulfide cobalt, cobalt oxalate, calcination, nitric acid dissolution, evaporation crystallization, etc.
- the final Co(N0 3 ) 2 .6H 2 0 purity is as high as 99% or more, but since the method does not reduce the spent catalyst and the intermediate product CoS grains formed during the recovery process are fine, the filtration is difficult, and the cobalt is easily lost. Thus, the recovery rate of cobalt is reduced to about 92%. Summary of the invention
- the object of the present invention is to provide a method for preparing high-purity cobalt nitrate crystals using a Co/SiO 2 spent catalyst with high recovery rate and high product purity.
- the present invention provides a method for preparing high-purity cobalt nitrate crystals by using a Co/SiO 2 spent catalyst, comprising the following steps:
- Co/Si0 2 spent catalyst to be treated is calcined at 350-500 ° C for 3-6 h under air, cooled to room temperature and ground to a powder;
- the flow rate of the mixed gas is controlled to be 1000 to 4000 h" 1 , the pressure in the reactor is 0.1 to 1 MPa, and the reaction temperature is 350 to 750 °C.
- the concentration of the dilute nitric acid in the step 3) is controlled to be 1 to 3 mol/L. Further, the concentration of the dilute nitric acid solution in step 6) is controlled to be 1-3 mol/L.
- the water bath temperature in step 4) is controlled to 70 ° C
- the oxalic acid solution is preheated to 70 ° C
- the washing is preheated to 70 ° C with deionized water.
- the reduction reaction is controlled, the volume fraction of H 2 in the mixed gas is 50% or more, and the cobalt in the spent catalyst can be sufficiently reduced, and the reduced product of the catalyst is sufficiently dissolved in a dilute nitric acid to obtain a cobalt nitrate solution. Then, the cobalt nitrate solution is fully reacted with the oxalic acid solution to form a cobalt oxalate precipitate.
- the excessive oxalic acid control in the step reaction is favorable for the complete precipitation of the cobalt and the conversion of the cobalt; and the pH of the solution is strictly controlled during the reaction between the cobalt nitrate and the oxalic acid.
- the value is 1.5, because only at this pH value can ensure the complete precipitation of cobalt oxalate; the temperature of the solution during the reaction is controlled to 25 ⁇ 80 °C, preferably controlled at 70 °C, because if the temperature control is too low, the generated Cobalt oxalate particles are fine, which will cause a large loss in the subsequent filtration and washing steps; because the reaction forms a precipitate of cobalt oxalate, the released hydrogen ions reduce the pH of the solution, in order to complete the cobalt precipitation, the reaction The pH adjustment must be controlled at 1.5 at the end point.
- the invention not only has high recovery rate but also high purity by strictly controlling the process conditions in the reaction process, and the product can be directly used in the production of Fischer-Tropsch synthesis catalyst for indirect liquefaction of biomass to synthetic oil. Moreover, the method of the invention has simple operation, short process, low requirements on equipment and process conditions, and is suitable for large-scale industrial application. detailed description
- the purity of the product was determined to be 99.63% according to the method provided in GBT 15898-1995, and the recovery of cobalt in this example was 96.64%.
- the purity of the product was determined to be 99.55% according to the method provided in GBT 15898-1995, and the recovery of cobalt in this example was 97.04%.
