Background technology
Scape technology
Along with the use of dense medium cyclone in constantly deterioration, the increasing of mechanical coal mining ratio and the coal separation operation of coal field geology condition, enter to wash coal slurry content in raw coal more and more higher.Coal slime flotation is to process fine particulate coal most common method.Coal slime flotation is dependent on the difference of coal and spoil surface wettability, realizes the process separated at boundary.Owing to the difference of coal with spoil self-faced character cannot efficiently separate, generally require in floatation process addition floating agent to change the hydrophobicity on coal surface, improve coal floatability, it is achieved coal efficiently separates with spoil.Conventional floating agent has collecting agent, foaming agent and composite drug.
Collecting agent is important floating agent, can be divided into anionic, cationic, amphoteric and nonionic by ionic nature.Non-polar hydrocarbon oil is the main collecting agent of current coal separation, and domestic and international coal preparation plant commonly uses collecting agent the oil product such as kerosene, diesel oil, accounts for the 80%-90% of collector dosage, and the non-polar hydrocarbon oil of some synthetic, such as BET, FS series collecting agent etc..Foaming agent is a kind of surfactant, is made up of hydrophilic polar group and hydrophobic nonpolar group.The most conventional foaming agent mainly has natural foaming agent, industry byproduct foaming agent and synthetic foaming agent 3 kinds.Composite drug is the multi-functional floating agent integrating collecting performance, frothing capacity, and some composite drug also has dispersion, effect of solubilising concurrently.Composite drug has the advantages such as flotation speed is fast, medicine consumes less, easy to use, but it has certain selectivity to ature of coal.
Aromatic hydrocarbons residual liquid, due to composition complexity, is the most reasonably reclaimed and is utilized, after generally going through simple separation, poor as fuel sales economic benefit.Therefore, utilize aromatic hydrocarbons residual liquid to produce coal separation composite drug, replace kerosene or diesel oil, be possible not only to save the energy, reduce coal separation cost simultaneously.
Summary of the invention
For traditional diesel oil+sec-octyl alcohol medicament, bad dispersibility is there is during coal slime flotation, reagent consumption amount is big, the problems such as flotation effect is general, the present invention provides a kind of coal separation composite drug and preparation method thereof, and this coal separation composite drug can not only improve the hydrocarbon-type oil selectivity to cleaned coal, improve flotation effect, save flotation cost, and Appropriate application aromatic hydrocarbons residual liquid has produced high value-added product, has good economic benefit and social benefit;Additionally, using aromatic hydrocarbons residual liquid as the raw material of coal separation composite drug, have have no irritating odor, good stability, preparation technology simple, on the premise of floating essence productivity, tail coal ash all have improvement, rate of economizing gasoline is up to 25%;Be conducive to energy-saving and emission-reduction, the advantage such as increase economic efficiency simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of coal separation composite drug and preparation method thereof, its raw material includes: aromatic hydrocarbons residual liquid, octyl alconyl residual liquid, light diesel fuel, emulsifying agent, water;Described aromatic hydrocarbons residual liquid is that petroleum chemical enterprise refines the residual liquid produced in purification process at aromatic hydrocarbons C10;Described octyl alconyl residual liquid is that under rhodium catalyst, through the by-product that rectification and purification obtains, outward appearance is light yellow liquid with propylene and synthesis gas as raw material;Described light diesel fuel is formed by component blendings such as straight-run diesel oil, catalytic cracking diesel oil, hydrogenated diesel oil and coker gas oils, selects the light diesel fuel of No. 0;Described emulsifying agent is dodecylbenzene sodium sulfonate, content concretely 1%, 3%, 5%.
This kind of coal separation composite drug is made up of the material of following mass percent: aromatic hydrocarbons residual liquid 65%, octyl alconyl residual liquid 15%, light diesel fuel 5%, emulsifying agent 1%-5%, water 10%-14%.
The preparation method of this kind of coal separation composite drug is as follows:
The most first the mixing of aromatic hydrocarbons residual liquid, octyl alconyl residual liquid and light diesel fuel ratio on request is put in the reactor of band stirring, stir 30min, form mixed oil liquid;2. emulsifying agent is mixed with water ratio on request, obtain the mixed liquor of emulsifying agent and water;3. with the stir speed (S.S.) of 100rmp, under conditions of stirring, adding the mixed solution that step is 2. obtained in the mixed oil liquid that 1. step obtains, continuing stirring to solution is brown.
The invention has the beneficial effects as follows: this coal separation composite drug can not only improve the hydrocarbon-type oil selectivity to cleaned coal, improve flotation effect, save flotation cost, and Appropriate application aromatic hydrocarbons residual liquid has produced high value-added product, has good economic benefit and social benefit;Additionally, using aromatic hydrocarbons residual liquid as the raw material of coal separation composite drug, have have no irritating odor, good stability, preparation technology simple, on the premise of floating essence productivity, tail coal ash all have improvement, rate of economizing gasoline is up to 25%;Be conducive to energy-saving and emission-reduction, the advantage such as increase economic efficiency simultaneously.
