Description

Utilize waste polymer containing heteroatoms through cracking to prepare the method for fuel oil
Technical field
The invention belongs to waste polymer and reclaim preparation fuel oil technical field, be specifically related to a kind of two-step approach of using, be that solvent edman degradation Edman and catalytic cracking solution are received back and forth and contained the novel method of heteroatoms waste polymer with the preparation fuel oil: earlier under the condition of gentleness, remove assorted element (N, Br, Cl, S etc.) in the system, will remove heteroatomic polymkeric substance again and carry out catalytic pyrolysis to produce fuel oil by degrading solvent.
Background technology
Energy and environment are the two principal themes that cause that the world today shows great attention to.Along with polymkeric substance in people's production, life widespread use and a large amount of waste polymers of thereupon bringing not only cause serious environmental to pollute, also cause the significant wastage of social resources simultaneously.
In order to eliminate the environmental pollution that waste polymer brings, make full use of these physical resources, at present, its method of handling roughly is divided into following four kinds: landfill method, burning method, regeneration method and thermochemical cycle.What wherein be considered to most worthy is thermochemical cycle, and this method is that waste polymer is carried out thermal destruction under inert atmosphere, finally obtains corresponding monomer or petroleum chemicals.
But waste polymer is a very complicated system, and it contains assorted element usually, as N, Br, Cl, S etc.As mainly by the waste polymer that electronic and electrical equipment produced of high-impact polystyrene (HIPS) and acrylonitrile-butadiene-styrene terpolymer preparations such as (ABS), in the cracked oil of its generation because of containing itrogenous organic substance, when acting as a fuel, it can produce HCN when using, objectionable impuritiess such as NOx can't be used the fuel oil that makes.In addition, because this series products all has higher requirement to flame retardant resistance, in order to reach fire-retardant purpose, all having added a certain amount of fire retardant man-hour mostly adding, is many with halogen-containing flame retardant wherein, as Polybrominated biphenyl, tetrabromo-bisphenol etc., thereby make bromine content in the goods up to 4-7wt%.Can produce hydrogen halide on the one hand when these contain the waste polymer cracking of halogen, severe corrosion equipment also can produce halogenous organic compound on the other hand, thereby the liquid that its cracking is generated acts as a fuel and can generate toxic gas when using.Therefore, brought great difficulty, become the technical barrier that solution is badly in need of in this field to these recovery that contain heteroatomic polymkeric substance.
At present, the research of investigator in this field has both at home and abroad obtained certain progress.As aspect the catalytic pyrolysis dehalogenation, adopted in system, to add single catalyst or composite catalyst, and be aided with technical measures such as different atmosphere (nitrogen, ammonia or air) and contact mode.What single catalyst adopted is metal oxide and its esters.Metal oxide comprises: alkaline earth metal oxide such as MgO, CaO, BaO etc.; Transition metal oxide such as Fe 2O 3, Co 2O 3, Ni 2O 3, La 2O 3, CeO 2, Nd 2O 3, TiO 2Deng; Other main group metal oxide compound such as Al 2O 3, (L.Tiikma, L.Johannes, H.Luik, J.Anal.Appl.Pyrolysis, 2006,206 (75): 205 such as PbO; Y.Masuda, J.Anal.Appl.Pyrolysis, 2006,160 (77): 159; J.Wootthikanokkhan, A.Jaturapiree, V.Meeyoo, J.Polym.Environ.2003,11 (1): 1).What composite catalyst mainly adopted is load carbon catalyzer and load oxide catalyst, as Ca-C, Fe-C, Ca-Zn, NiMo/Al 2O 3, (N.S.Vrandecic, I.Klaric, T.Kovacic, J.Thermal Anal.Calorimetry, 2003,74 (1): 171 such as metalloscene catalyst and compound solid-acid FSZ; S.L.Gupte, N.Agarwal, G.Madras, K.Nagaveni, M.S.Hegde.J.Appl.Polym.Sci., 2003,90 (13): 3532; T.Bhaskar T.Matsui, J.Kaneko, Greem Chem., 2002,4 (4): 372; M.Brebu, E.Jakab, Y.Sakata, J.Anal.Appl.Pyrolysis, 2007,79 (1-2), 346); M.Brebu, M.A.Uddin, A.Muto, Y.Sakata, C.Vasile, J.Anal.Appl.Pyrolysis, 2002,63 (1): 43).Although obtained certain progress by the pyrolysis method recovery, well remove heteroatomic effect but still can not reach, make the fuel oil that makes can't satisfy the standard of fuel oil.In addition, catalyzer exists easily poisons, and the life-span is short, problems such as regenerability difference, and this has become current obstruction cracking process and has reclaimed the key issue that contains the heteroatoms waste polymer.
In polymer recovery, except passing through pyrolysis method, existing investigator also attempts adopting the degrading solvent method to carry out the dehalogenation reaction, and also adopt some subsidiary conditions to carry out simultaneously, as microwave (M.Ito, K.Ushida, N.Nakao, Polym.Degrad.Stab., 2006,91 (8): 1694), overcritical (A.J.M.Lagadec, S.B.Hawthorne, Envioron.Sci.﹠amp; Tech., 2002,36 (6): 1337) etc.Adopt degrading solvent method dehalogenation can not only effectively avoid pyrolysis method need add efficient catalytic agent and complicated catalysis dehalogenation technology, and because degrading solvent method and unlike thermo-cracking, follow free radical reaction course dehalogenation, but carry out with ionic species, thereby its dehalogenation reaction activation energy is significantly less than thermo-cracking dehalogenation reaction activation energy, makes dehalogenation easier.As Mihai Brebu etc. (M.Brebu, T.Bhaskar, A.Muto, Y.Sakata, Chemosphere, 2006,64:1021) adopt the debrominate of hot alkaline solution method, obtained higher debrominate rate; (M.Saburo such as Saburo Moriwaki, M.Motoi, T.Hideki, Appl.Thermal Eng., 2006,26 (7): 745) studied the dechlorination situation of PVC in commercial microwave oven, found that microwave absorbing subsidiary such as gac and iron can promote PVC dechlorination and decomposition effectively, the dechlorination rate of discarded PVC can reach more than 90% under microwave condition.
Although the degrading solvent method has above advantage, main chain is not contained heteroatomic polymkeric substance, adopt degrading solvent method polymer pyrolysis effectively; And, then needing higher temperature and pressure if will make the further cracking of polymkeric substance generate micromolecular compound, this needs special reaction unit to bear high temperature and high pressure.On the other hand, higher to remove the then required reaction times of heteroatomic degree longer if will reach under the condition of gentleness, and efficient is lower; And, then need higher temperature and pressure again if will rapidly and efficiently remove heteroatoms, conversion unit is had relatively high expectations.
