Abstract
The invention discloses a preparing method of industrial gas rare earth additive, which comprises the following steps: adding acetone into kalii permangana at normal temperature and normal pressure; dissolving completely; adding into hydrogen dioxide solution; aging; producing A solution; adding ether into bis iron; stirring to dissolve completely; aging; producing B solution; mixing methyl alcohol and acetone; adding into rare earth salification; dissolving completely; aging; producing C solution; mixing A, B and C solutions with finite proportion; stirring completely; aging; getting the additive. This additive possesses merits of safe and economical, which can be added into by-product of oil with 4-6 per mill proportion and replace the ethine gas.
Description
Technical field
The present invention relates to a kind of preparation method of industrial combustion gas rare earth addition agent, refer in particular to the method that wet type prepares rare earth addition.
Background technology
The existing history that goes up a century of the development of industrial combustion gas.Along with the continuous progress of suitability for industrialized production and people to the improving constantly of environmental energy scientific knowledge, also more and more higher to the requirement of industrial combustion gas technical products.
Acetylene gas is traditional industrial combustion gas, and its chemical property is active, explosive (limits of explosion is 2.4-80%), and murther.The molecular structure of acetylene under normal temperature, normal pressure is unsaturated link(age), it is very unstable to be heated, meeting polymerization reaction take place when being higher than 200 ℃, make the continuous rising of temperature, pressure and cause blast, it mixes with metal such as copper, silver, aluminium and air, pure oxygen, even fills container diameter and all can set off an explosion when big.
The raw material of producing acetylene is a calcium carbide, and one ton of calcium carbide of every production needs power consumption 3300 degree, also needs 600 kilograms of cokes, 500 kilograms in coal, 50 kilograms of carbons.Simultaneously, when getting acetylene gas, can discharge a large amount of carbide slags and H with the calcium carbide legal system
2S, PH
3Deng toxic and harmful, environmental pollution is serious.In addition, acetylene still is the valuable raw material of chemical industry aspect, is waste to resource as combustion gas only with acetylene.Now, the occupation rate of developed country's acetylene gas in industrial circle is about 5% in the world, and the occupation rate of China is 70%.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of preparation method of industrial combustion gas rare earth addition agent, industrial combustion gas rare earth addition agent with present method preparation joins the middle byproduct of oil, as: in liquefied petroleum gas (LPG), propane, propylene, the Sweet natural gas, promptly be mixed with the infant industry combustion gas.
Technical problem of the present invention is solved by following scheme: a kind of preparation method of industrial combustion gas rare earth addition agent, it is characterized in that: under normal temperature, normal pressure, add potassium permanganate with acetone, fully the dissolving back adds hydrogen peroxide, A solution is made in ageing more than 4 hours, in the A solution, the weight ratio of potassium permanganate, hydrogen peroxide, acetone is 1: 1～2: 2～3; To add ferrocene in the ether, stirring makes it fully dissolve the back ageing and makes B solution more than 4 hours, and in the B solution, the weight ratio of ferrocene, ether is 1: 10～20; Mixing back adding rare earth salt with acetone with methyl alcohol fully dissolves, C solution is made in ageing more than 4 hours, in the C solution, rare earth salt, acetone, the shared weight ratio of methyl alcohol are 1: 1.5～2.5: 2.5～3.5, the solution that A, B, three kinds of ageings of C are good mixes by 1: 2.5～3.5: 5～7 weight ratio, fully stir again, promptly make industrial combustion gas rare earth addition agent more than 48 hours through ageing.
In the ratio of 4-6 ‰, this industrial combustion gas rare earth addition agent is joined the middle byproduct of oil, as: in liquefied petroleum gas (LPG), propane, propylene, the Sweet natural gas, promptly be mixed with the infant industry combustion gas.
Advantage of the present invention is:
1, environmental protection: low radiation, over-emitting black exhaust, flue dust do not have harmful poisonous residue.Give salubrious Working environment of staff.
2, safety: limits of explosion is 2.4-10%, has only 1/8 (limits of explosion of acetylene gas is 2.4-80%) of acetylene gas.Not tempering during use, non-naked light can not be lighted, and is difficult for decomposition explosion, and transportation, the safety standard that stores and general Sweet natural gas, liquefied petroleum gas (LPG) are just the same.
3, energy-conservation: its parent medium raw material is the petrochemical complex intermediates, as: liquefied petroleum gas (LPG), Sweet natural gas, propane, propylene etc., wide material sources, cheap, production process is pollution-free, uses the no raffinate in back, can be rated as green industrial combustion gas.
4, economy: from theoretical calorific value and practice effect, the infant industry combustion gas of one bottle of this industrial combustion gas rare earth addition agent of usefulness preparation is equivalent to 5 bottles of acetylene gass, and does not increase oxygen depletion; Its temperature height (can reach 3300 degree), preheating cutting speed in feet per minute fast (processing work speed is than acetylene fast 1/3), narrow, the saving starting material of slot; Cut surface is bright and clean, and carbon distribution and hardening phenomenon do not take place on the surface, and welding quality is good, thereby has saved cleaning and postorder process period, has also alleviated the process tool wearing and tearing.Through estimation, its overall economic efficiency is than using acetylene gas to improve more than 50%.We can say that the infant industry combustion gas that makes with this industrial combustion gas rare earth addition agent can substitute acetylene gas cutting fully, welds, bake school, spraying, is real environmental protection and energy saving product.

Embodiment
Under normal temperature, the normal pressure, add the potassium permanganate of 20 grams in the acetone of 50 grams, fully add the hydrogen peroxide of 30 grams after the dissolving again, A solution was made in ageing in 4.5 hours; The ferrocene that adds 20 grams in the ether of 280 grams, stirring make it fully dissolve the back ageing and made B solution in 4.5 hours; Methyl alcohol with 300 grams mixes the fully dissolving of cerous nitrate (rare earth salt) that the back adds 100 grams with the acetone of 200 grams, C solution was made in ageing in 4.5 hours.The solution that A, B, three kinds of ageings of C are good fully stirs after mixing again, promptly makes industrial combustion gas rare earth addition agent in 50 hours through ageing.
