Description
Technical field
The present invention relates to environmental friendly catalysis field, specifically utilize a kind of method that polyether-type vanadyl heteropolyacid ionic liquid is catalyst fuel oil oxidation sweetening.
Background technology
The SOx that oil inflame gives off is one of important factor causing topsoil, and countries in the world have promulgated strict fuel oil sulfur-bearing standard in succession.At present, developed country performs Europe V standard just in succession, and namely sulphur content is lower than 10 μ g/g.Although China has also issued the state V standard identical with Europe V, at present still at execution state IV standards, namely sulphur content has been 50 μ g/g.Although current commercially available petrol and diesel oil is stripped of mercaptan, thioether sulfides wherein through Catalytic Hydrogenation Techniques, still containing thiophene, thionaphthene and dibenzothiophene class sulfide that micro-difficulty removes in oil product.Therefore, realize the target that China's petrol and diesel oil sulphur content reaches Europe V standard, key is to remove above-mentioned thiophene-type sulfide how efficiently.
In current existing non-hydrodesulfurization, the most potential desulfurization technology is catalytic oxidation desulfurization.Catalytic oxidation desulfurization technology is under the catalysis of catalyzer, utilize oxygenant by polarity for the sulfide-oxidation in oil product large sulfone, sulfoxide, recycling fuel oil and sulfone, feature that sulfoxide polarity gap is large, by extracting or adsorbing, isolate sulfone, sulfoxide, thus reach the object of desulfurization.Therefore, oxidation sweetening more easily removes in hydrogenating desulfurization, be difficult to removal thionaphthene and dibenzothiophene class sulfide.
In current existing catalytic oxidation desulfurization technology, with hydrogen peroxide (H
2o
2) technology the most ripe (Ind.Eng.Chem.Res., 2010,49,11760 of making oxygenant; Ind.Eng.Chem.Res., 2010,49,8998; Chem.Eur.J., 2012,18,4775; EnergyFuels, 2014,28,2754; CN104689850A; CN104312621A; CN103666536A; CN103333711A).Due to O
2or air is that oxygenant can overcome H
2o
2be heated and the intrinsic shortcoming such as easily decompose, be considered to a kind of rising eco-friendly fuel desulfuration technology.But, with O
2or air is oxygenant, its oxidation activity comparatively H
2o
2relatively low, need to carry out under the catalysis of catalyzer, sometimes also need the existence of co-oxidation sacrifice agent aldehyde.The O of catalysis
2oxidation sweetening has document and patent report (Fuelprocessingtechnology, 2009,90,317; EnergyFuels, 2004,18,116; CatalToday, 2007,123,276; CN103834432A).Heteropllyacids compound containing high-valence state transition metal is used as oxide catalyst, and arouse widespread concern, it is for catalytic oxidation desulfurization, shows good catalytic effect (GreenChem., 2010,12,1954; Chem.Commun., 2012,48,11647; Chem.Commun.2007,2,150; Catalysis journal, 2014,35,1433).But current Problems existing: one is that the catalytic activity of catalyzer need further raising, to realize the oxidizable object removed completely of thiophene-type sulfide in fuel oil; Two be catalyzer recycle weak effect.The reason that catalyst activity is low: one is because the catalyzed oxidation ability of catalyzer itself is low; Two is because current oxidation sweetening system still belongs to solid-liquid or liquid-liquid two-phase system, catalyzer with reaction substrate contact area is little, mass transfer diffusional resistance greatly, cause speed of reaction slow.
Ionic liquid has that structure can design, character controllable, advantages of environment protection, utilizes its structure designability, catalytic active center can be assembled in ionic liquid structure, make it while having catalytic activity, guarantee reusing of ionic liquid.But constructed reaction system majority is biphasic catalysis, speed of response is obviously not as homogeneous catalysis.Therefore, the ideal response system that ionic liquid participates in should be, during pyroreaction, ionic liquid and reactant coexist a phase, reaction terminates rear ionic liquid and product office two-phase again, reach the object of " high temperature homogeneous reaction; low temperature two-phase laminated flow ", the recovery of realization response-isolation integral and ionic liquid and reusing.
Summary of the invention
In order to solve, the catalyst activity existed in existing desulfurization technology is low, the dysoxidizable problem of thiophene-type sulfide, the present invention proposes a kind of method that polyether-type vanadium oxa-polyacid ionic liquid is catalyst fuel oil oxidation sweetening.The method technique is simple, and catalyst activity is high, it is effective to recycle, for deep desulfurization of fuel oil provides an eco-friendly operational path.
The present invention utilizes the designability of ionic liquid structure, structure of controlling temperature unit (polyether chain) is incorporated in the cationic structural of ionic liquid, in the positively charged ion that high-valence state vanadium atom is incorporated into ionic liquid or anion structure, and the heteropolyacid root be made up of high-valence state tungsten is designed to the negatively charged ion of ionic liquid, formulate out new class and there is catalyzed oxidation and the bifunctional ionic-liquid catalyst of temperature control, for the O of catalysis fuel oil
2oxidation sweetening.The feature of this catalyzer is: (1) has vanadium and tungsten two kinds of catalytic oxidation activity centers simultaneously, gives the catalytic activity that catalyzer is higher; (2) there is unique temperature-control performance, give the feature that catalytic desulfurization system has " high temperature homogeneous reaction; low temperature two-phase laminated flow ", during high temperature, catalyzer can carry out with the oxidation desulfur reaction of sulphur-containing burning oil in a phase, and reaction terminates automatically to be separated into two-phase again to catalyzer during room temperature and fuel oil.Therefore, new desulfurization system can solve low, the dysoxidizable problem of thiophene-type sulfide of catalytic activity that current oxidation sweetening catalyst system exists effectively, reaches the object of deep desulfurization of fuel oil.
Technical scheme of the present invention is:
In autoclave, add a certain amount of catalyzer, sulphur-containing burning oil and temperature control solvent toluene, with the air several in replacement of oxygen still, be then filled with the oxygen of certain pressure, heat and open magnetic agitation, reacting certain hour at a certain temperature.After reaction terminates, be cooled to room temperature, release, drive still.Catalyzer phase and the layering of oil product phase, the oil product on upper strata, with after isopyknic DMF (DMF) extraction, measures desulfurization degree; The catalyzer of lower floor without the need to process, direct reuse.
