Description
Technical Field
The invention relates to a method for preparing an ultra-low mercury catalyst by recycling waste batteries, belonging to the technical field of recycling of waste batteries.
Background
China is the largest world for battery production and consumption, and the yield of primary batteries has far exceeded the U.S. and japan, and is the first world; the secondary battery production also has been in japan and korea only and, after that, is the third world. In 2011, the yield of the battery in China reaches about 372.66 hundred million, wherein 341.6 hundred million primary batteries and 341.4 hundred million secondary batteries (1.4 hundred million lead-acid batteries and 29.66 hundred million lithium-ion batteries) are used. With the wide application and technical update of secondary batteries in industries such as smart phones, digital cameras, new energy vehicles and the like, waste batteries are inevitably generated, so that the recycling of the waste batteries is very important.
At present, the recovery and utilization of waste batteries generally includes roasting and reducing elemental valuable metals in the waste batteries, for example, the recovery method of metal elements in the waste nickel-metal hydride batteries of chinese patent CN103031441B, and the recovery method of metal elements in the waste nickel-metal hydride batteries includes the steps of reducing and roasting, recovering rare earth elements, recovering manganese, recovering nickel and cobalt, and the like. Chinese patent CN101451246B discloses a method for recovering metals from waste nickel-cadmium batteries, which comprises contacting the waste residue obtained after removing organic substances from the waste nickel-cadmium batteries with a solution capable of sufficiently dissolving the metals in the waste residue into an ionic state, so that the metals in the waste residue exist in an ionic form; and then filtering to obtain filtrate, wherein the method further comprises electrolyzing the filtrate under the conditions that the current density is 80-120A/m2 and the pH value is below 2 to obtain the metal cadmium. The recovery of the waste battery has the problems of single recovery of valuable metals, insufficient utilization rate, higher cost and the like.
Disclosure of Invention
The invention aims to provide a method for preparing an ultra-low mercury catalyst by recycling waste batteries. The chloroethylene synthesis catalyst is prepared by separating valuable metal elements in the waste batteries, so that the waste batteries are recycled.
The technical scheme of the invention is as follows:
a method for preparing ultra-low mercury catalyst by recycling waste batteries is used for extracting and separating valuable elements from battery powder obtained by disassembling waste batteries to prepare ultra-low mercury catalyst synthesized by vinyl chloride, and comprises the following steps:
s1, stirring and extracting battery powder obtained by disassembling the waste batteries and dilute hydrochloric acid, and taking extract liquor;
s2, after filtering and separating the extract, analyzing the content of mercury, zinc, manganese, copper, cadmium, nickel and cobalt in the extract, adding a regulator by weight, and regulating the ratio of mercury, zinc, manganese, copper, cadmium, nickel and cobalt in the extract to 3-5: 2-6: 1-5: 0.1-2 to obtain a regulated solution;
and S3, adding activated carbon into the adjusted solution, soaking and drying to obtain the ultra-low mercury catalyst.
In the step s1, adding the battery powder and the dilute hydrochloric acid into a stirring tank, dropwise adding hydrogen peroxide at 40-70 ℃, stirring and reacting for 20-120 minutes until the battery powder is not dissolved any more, taking the supernatant, adding calcium carbonate powder, and removing sulfate ions to obtain the extract, wherein the concentration of the hydrochloric acid is 0.3-1 mol/L.
In the method for preparing the ultra-low mercury catalyst by recycling the waste batteries, in the step s1, the battery powder and the dilute hydrochloric acid are added into a stirring tank, hydrogen peroxide is dropwise added at 50-60 ℃ to react for 40-100 minutes under stirring, and the concentration of the hydrochloric acid is 0.5-0.8 mol/L.
In the method for preparing the ultra-low mercury catalyst by recycling the waste batteries, the regulator is mercury chloride, zinc chloride, manganese chloride, copper chloride, cadmium chloride, nickel chloride and cobalt chloride.
In the method for preparing the ultra-low mercury catalyst by recycling the waste batteries, the ratio of mercury, zinc, manganese, copper, cadmium, nickel and cobalt in the solution is adjusted to 3-4: 3-5: 2-4: 0.5-1.5.
According to the method for preparing the ultra-low mercury catalyst by recycling the waste batteries, the ratio of mercury, zinc, manganese, copper, cadmium, nickel and cobalt in the solution is adjusted to be 4: 5: 3: 1.
Has the advantages that:
the battery powder obtained by currently disassembling and recycling waste batteries contains: 10-12% of Mn; ni 32-35%; co 10-20%; in addition, the alloy also contains heavy metal elements such as copper, cadmium, mercury and the like and other impurity elements. The recovery cost of recovering a single metal is very high and uneconomical. The applicant found in previous studies that: the metal elements in the recovered waste batteries can be used for preparing the ultra-low mercury catalyst for synthesizing the chloroethylene after chlorination extraction.
Chloroethylene is a monomer of polyvinyl chloride (PVC) which is one of five synthetic resins in the world, and is mainly produced by a calcium carbide acetylene method and a petroleum ethylene method. The energy structure of China is rich in coal, lean oil and little gas, and it is determined that the calcium carbide acetylene method is a main process for producing vinyl chloride in China continuously in a long time in the future, namely mercury chloride catalyzes acetylene to react with hydrogen chloride to generate vinyl chloride. Under the international mercury constraint, a new high-efficiency ultralow-mercury catalyst needs to be developed to replace the traditional mercury chloride catalyst.
The research of the applicant finds that the metal elements in the battery powder obtained by disassembling and recovering the waste batteries can be used for preparing a multi-metal composite ultra-low mercury catalyst for a vinyl chloride catalyst, but the content of various elements in the battery powder recovered by different manufacturers and batches has certain difference, so that the invention mixes the battery powder and dilute hydrochloric acid, dropwise adds hydrogen peroxide, stirs and extracts to obtain a metal ion extraction liquid containing mercury, zinc, manganese, copper, cadmium, nickel and cobalt, adds a regulator according to the content of various ions in the extraction liquid, adjusts the proportion of mercury, zinc, manganese, copper, cadmium, nickel and cobalt in the extraction liquid, and prepares the ultra-low mercury catalyst which can be used for vinyl chloride synthesis.
To further demonstrate the catalytic effect of the catalyst prepared by the present invention, the inventors prepared a batch of 5 tons of ultra-low mercury catalyst with the adjusted solution of mercury, zinc, manganese, copper, cadmium, nickel and cobalt in a ratio of 4: 5: 3: 1, tested on the 66# converter of inner Mongolia chemical company Limited (Table 1, example 2), prepared 10 tons of ultra-low mercury catalyst with the adjusted solution in other ratios, and tested on the 56# and 68# converters of inner Mongolia chemical company Limited (Table 1, examples 1 and 3) to show that: the catalyst for synthesizing chloroethylene is prepared by using the battery powder obtained by disassembling the battery, when the chloroethylene is synthesized, the reaction temperature is 110-; the purity of the chloroethylene crude product after rectification reaches 99.99V/%. Can meet the production requirement of chloroethylene.
TABLE 1 test results of vinyl chloride Synthesis test
Analysis on the result of a chloroethylene synthesis test shown in Table 1 shows that the method for recovering the ultralow mercury catalyst prepared from the waste battery to produce chloroethylene has the reaction temperature of 110-; the purity of the chloroethylene crude product after rectification reaches 99.99V/%. Can meet the production requirement of chloroethylene.
The technical scheme of the invention provides a process method for preparing a chloroethylene catalyst by using battery powder and a catalyst proportion with high catalytic efficiency. The comprehensive recovery and high-efficiency utilization of metal elements in the battery powder are realized.
