Method for extracting tungsten, titanium and vanadium from waste SCR (selective catalytic reduction) catalyst

The invention discloses a method for extracting tungsten, titanium and vanadium from a waste SCR (selective catalytic reduction) catalyst, which comprises the following steps: crushing the waste SCR catalyst, adding a strongly alkaline solution, and reacting; filtering, separating, then adding strong acid into the sodium tungstate and sodium vanadate mixed solution, and reacting to obtain tungstic acid and a sodium salt and vanadic acid mixed solution; regulating the pH value of the sodium salt and vanadic acid mixed solution until precipitate is separated out, thus obtaining ammonium vanadate; then adding sulfuric acid into the tungsten-and-vanadium-removed SCR catalyst, and reacting to obtain a titanyl sulfate solution and solids such as aluminum slag and the like; then adding water into the titanyl sulfate solution, and hydrolyzing to obtain titanic acid and a waste acid solution; and finally, respectively calcining the obtained ammonium vanadate, tungstic acid and titanic acid to obtain vanadium pentoxide, tungsten trioxide and titanium dioxide. According to the invention, tungsten, titanium and vanadium can be extracted from the SCR catalyst through the reaction with strong alkali and strong acid at a low temperature, the equipment requirement is low, the energy consumption is low, some products having added values can be coproduced, and no secondary pollution is generated, thereby facilitating popularization and application.

Liquid infusion method for producing linaloe on aquilaria sinensis trees

The invention belongs to biological technical field, in particular to a liquid infusion method for producing linaloe on aquilaria sinensis trees. The method includes of drilling on the aquilaria sinensis trunk, gradually dropping a linaloe catalyst into the aquilaria sinensis tree body through the liquid infusion method; the operation is repeated every 2-3 months, after 6-12 months, the chocolatebrown oil-like material and the yellowish-brown discolored eaglewood formed in the trunk is cut and is dried to obtain the linaloe; the linaloe catalyst is mixed up by a phytohormone solution and a chemical reagent solution; the chemical reagent is ferric salt or sodium salt. The process of the invention has simple technique, convenient operation, can greatly increase production quantity of the linaloe and greatly shorten the production period of the linaloe through the inducing method, has good linaloe-forming effect, can effectively ease the contradiction between supply and demand for sinensis, is applicable to large-scale standardization and commercialization production, provides a new effective path for protecting, developing and utilizing the aquilaria sinensis tree resources, and has important economical, social and ecological benefits.

Method for preparing lithium carbonate by extracting lithium from lepidolite

The invention relates to a method for preparing lithium carbonate by extracting lithium from lepidolite. The method comprises the following steps of: a. calcination and defluorination at a high temperature; b. grinding; c. autoclaving; d. impurity removal; e. condensation; f. sodium separation by freezing; g. ithium precipitation by carbonization, wherein, in the step c, the grinded lepidolite, calcium oxide and sodium salt are thrown into a high-pressure kettle for autoclaving; the lepidolite is decomposed in the continuous stirring state; and alkali metal in the lepidolite is subject to ion exchange, turned into salt and dissolved out. In the step d, an autoclaving mother solution and autoclaving residues are obtained after separation and autoclaving; sodium hudroxide with slightly excess amount according to the Lithia content in the autoclaving mother solution is added and evenly stirred, then activated carbon is added for filtering and impurity removal. In the step g, CO2 is led to a sodium separation mother solution till the PH value of the solution is equal to between 9 and 10; the mother solution is heated, stirred, carbonized and subject to centrifugal water spinning and separation to obtain coarse lithium carbonate; backwashing and drying are carried out to the coarse lithium carbonate, thereby obtaining a product of lithium carbonate. The method has the advantages that: the method has high lithium yield rate; residues can be utilized; and sodium salt can be recycled, etc.
