Abstract
The present invention extracts to reclaim metallic nickel and magnesian processing method and product from the nickel-containing catalyst waste material.Known employing extraction process reclaims nickel, cobalt, molybdenum from alloy, the extraction agent that it adopts, and for example TBP is very rare.And the method that reclaims nickel from the catalyzer waste material still is not reported.Method of the present invention is the nickel-containing catalyst waste material that purifying treatment is crossed, and filters sedimentation and filtration through leaching; The filter residue of sedimentation and filtration decomposes through roasting, obtains the magnesium oxide byproduct.The filtrate of sedimentation and filtration is precipitated through thermal degradation, and roasting is decomposed, and reduction obtains the metallic nickel product.Its advantage is that technology is easy, equipment is simple, energy consumption is low.
Description
The present invention relates to the method and the product of regeneration recovery metal from the catalyzer waste material.Particularly from the nickel-containing catalyst waste material, reclaim the method and the product of metallic nickel.
Known employing extraction process reclaims cobalt, molybdenum, nickel from alloyed scrap, the extraction agent that uses is TBP, secondary amine and tertiary amine (the extraction procedure Ma Rongjun that " application of solvent extraction in hydrometallurgy " the 222nd page of chapter 4 second joint cobalt, the nickel U.S. handle nickel cobalt waste material write metallurgical industry press 1979 years).And from the catalyzer waste material, reclaim the method for metallic nickel, in existing literature, do not find relevant report as yet.
The object of the present invention is to provide a kind of method and product that adopts hydrometallurgy from the nickel-containing catalyst waste material, to reclaim metallic nickel.
The present invention adopts hydrometallurgy, reclaims metallic nickel from RKNR, 3812, nickel-containing catalyst waste materials such as 3822, and is the processing method and the product of byproduct with magnesium oxide.Its technical finesse scheme is: purifies, leaches and filter, and sedimentation and filtration, filter residue is through roasting decomposition-acquisition magnesium oxide byproduct; Filtrate is precipitated through thermal degradation, and roasting is decomposed, reduction-acquisition metal nickel powder.
Purify: nickel-containing catalyst is in use poisoned because of being subjected to contaminating impurities such as carbon, sulphur, loses katalysis, and becomes waste material.The nickel-containing catalyst waste material is put into the process furnace roasting in kilns, and maturing temperature is 700～900 ℃, is incubated 0.5～2 hour, and nickel-containing catalyst is purified.
Leach and filter: the nickel-containing catalyst waste material that will be cleaned, adopt acids to dissolve leaching, filter, and repeat operand, the nickel in the waste material is dissolved fully.Filter residue discards.
Sedimentation and filtration, roasting is decomposed, and thermal degradation, precipitation, roasting are decomposed, reduction; In leaching the filtrate of filtering gained, add NH
4Inorganic precipitant such as OH, NaOH, and filter: filter cake-be that throw out is a magnesium compound, with its oven dry, decompose through roasting, maturing temperature is 450～600 ℃, obtains byproduct-magnesium oxide; Filtrate is nickeliferous complex compound, after being heated to boiling, add alkaline precipitating agents such as yellow soda ash, sodium hydroxide again, keep PH=7-11, obtain the nickel compound containing precipitation, after the filtration, with nickel compound containing precipitation oven dry, roasting to 500～700 ℃, be incubated 0.5～1 hour, nickel compound containing is decomposed, obtain nickel protoxide.Place tube furnace to heat nickel protoxide, and feed hydrogen and reduce, Heating temperature is 500～700 ℃, be incubated 0.5～2 hour, stops to be incubated.After treating that temperature is reduced to room temperature, just obtain metallic nickel.The extraction yield of metallic nickel is 85～95%.
The invention has the advantages that technology is easy, with short production cycle, production cost is low, equipment is simple, less investment, still can save the energy, reduce environmental pollution.That regeneration is reclaimed is effective, efficient is high.The good quality of product that obtains meets the production requirement of producing nickeliferous material and product.
Embodiment: the Chemical Composition of RKNR catalyzer is Ni25%, MgO64%, Al
2O
311%.Become waste material after using inefficacy.RKNR catalyzer waste material is put into the muffle furnace roasting, and temperature is 800 ℃, be incubated 1 hour, stops insulation, treat that its temperature is reduced to room temperature after, the RKNR catalyzer waste material that has just obtained being cleaned; With the RKNR catalyzer waste material that has been cleaned, adopt dissolving with hydrochloric acid to leach, and filter, repeat to leach filter operation, till filtrate does not present green.Filter residue discards; In leaching the filtrate of filtering gained, add NH
4OH makes it produce precipitation, and throw out is the compound of magnesium, filters.With behind the filter cake of sedimentation and filtration-be the compound precipitation oven dry of magnesium, place the muffle furnace roasting to decompose, maturing temperature is 550 ℃, obtains byproduct-magnesium oxide.Filtrate being of sedimentation and filtration contains nickel complex, is heated to boiling, after ammonia is got rid of, add yellow soda ash again, keep PH=9-10, obtain the nickelous carbonate precipitation, after the filtration, with filter cake-nickelous carbonate precipitation oven dry, roasting in muffle furnace, temperature is 600 ℃, be incubated 40 minutes, nickelous carbonate is decomposed, get rid of carbon dioxide, obtain nickel protoxide; Place tube furnace to heat nickel protoxide, and feed hydrogen, Heating temperature is 600 ℃, be incubated 1 hour, stops to be incubated, treat that temperature is reduced to room temperature after, just obtain metal nickel powder, the extraction yield of metallic nickel is 90%.
