Description
Technical Field
The invention relates to a supported non-noble metal catalyst, in particular to a catalyst for hydrodehalogenation of halogenated aromatic hydrocarbon, and preparation and application thereof.
Background
In recent years, it has become possible to provide,there is increasing interest in the integrated remediation of volatile halogenated aromatic contaminants, including Polychlorinated Biphenyls (Polychlorinated Biphenyls). The traditional method for eliminating halogenated aromatic pollutants is incineration, which often requires combustion temperatures higher than 1000 ℃ and large amounts of organic fuel, and is costly to invest and maintain, and more seriously, combustion under oxidizing conditions results in the higher toxic pollutant Dioxin (Dioxin)s) (including polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)). The catalytic combustion process can treat halogenated aromatic pollutants directly without adding fuel, but it is only suitable for treating pollutants with low content (<1%) and difficult recycling under gas phase conditions, see chinese patent application nos. 00110236.2 and 00122988.5.
Dioxin can be avoided by chemical reductionsThe activity of the reducing agent is very high, such as U.S. patents (publication numbers US4950833 and US6414212), european patents (publication number EP476053) and the like, which use sodium as the reducing agent; U.S. Pat. No. 4,430,870 for LiAlH4Is a reducing agent; U.S. Pat. No. 4,430,667 uses sodium naphthalene to dehalogenate aromatic halohydrocarbons; U.S. patent publication No. US 4910353; chinese patent application No. 95110017.3, dehalogenates aryl halohydrocarbons using sodium hydride as a reducing agent; these strong extremely active reducing agents have high dehalogenation efficiency, but they are extremely sensitive to airand water, are easily deactivated, and are potentially hazardous during storage and use.
The heterogeneous catalytic hydrogenation degradation of halogenated organic pollutants is a high-efficiency, energy-saving, economic and safe treatment method, and is more suitable for large-scale industrial treatment of organic wastes containing halogenated aromatic hydrocarbons. It is generally considered that the noble metal-based catalyst in which noble metals such as Pd, Pt, Rh and the like are supported on various carriers can achieve dehalogenation of halogenated aromatic hydrocarbons under mild conditions (Dini, P., Bart, J.C., Giordano, N.J.Chem.Soc., PerkinII, 1975, 1479; Laura P., Michele R., Appl.Catal.B: 1999, 23, 135; Carlos, A., Marques, M.S., Pietro T.J., Chem.Perkin., Trans., 1993, 1, 529; Yuji, U.S., Satoshi K., Tatsuo M.Appl.Catal.B: 2000, 27, 97; for example, Chinese patent application No. 93111071.8) can achieve complete conversion of chlorobenzene at 65 ℃ over 4 hours with a palladium complex supported on a polymeric carrier as a catalyst; U.S. Pat. No. 5,149,170 discloses Ru as the main component of the catalyst; the U.S. Pat. No. 5,515 (publication No. 5,5783515) uses Ir as the main component of the catalyst and can show higher activity under different conditions; also US patents (publication nos. US4749817 and US4618686) and so on. However, halogens or hydrogen halides generated during dehalogenation poison them and deactivate them quickly, and a large amount of expensive noble metals are used to prepare the catalyst.
Examples of catalysts that may be used include Ni, Mo, Co, Ni-Mo, Co-Mo, Fe (Hagh, B.F.; Allen, D.T. AICHE J.1990, 36(5), 773; Suzdoif, A.R.; Moroxv, S.V.; Anshits, N.N.; Tsiganova, S.I.; Anshits, A.G.Cat. Le1994, 29, 49; Gioia, E.; Famiglietl, V.; Murena, F.J.Hazard. Mater.1993, 33, 63; Hagh, B.F.; Allem, D.T.Chem.Eng.Sci.1990, 45 (8)), 2695; Moanrldo, R.ahan, S.E., Larser, D.En.W.1997, U.31, C.409; noble metals, which are most likely to be used in place of the same type of noble catalysts, and may be used in place of the inexpensive catalysts, not only noble metals, but are available, and are available; although they exhibit some stability, they generally require higher temperatures and higher pressures to exhibit some activity; as another example, U.S. Pat. No. 6,6271168 uses a Fe-P-S-Na complex catalyst to treat halogenated aromatics at 300 ℃.
Disclosure of Invention
The invention aims to provide a catalyst for hydrodehalogenation of halogenated aromatic hydrocarbon, which has high catalytic activity and mild reaction conditions, and preparation and application thereof.
In order to achieve the purpose, the invention adopts the technical scheme that:
the catalyst consists of a carrier and an active component, wherein the carrier is selected from Al2O3、SiO2Activated carbon, activated carbon,TiO2One or more of the active components, mainly Ni, and the loading amount of the active components is 0.1-30 wt%.
The active component is in the state of metal, metal oxide or other forms (such as aluminate, silicate, etc.) in the catalyst; the loading amount of the active component Ni is preferably 5-15%; the carrier is preferably activated carbon; the catalyst can contain a valence-variable transition metal element M as An auxiliary agent, wherein the M is selected from one or more of Co, Cu, V, Fe, Zn, An, Ag, Ce and Ln, and the molar ratio of the M to the main active component Ni is 1: 10-20; m is preferably one or more of Cu, Ag, Ce and Co;
the loading of active component nickel on the activated carbon is as follows: in general, the active components of the supported metal catalysts are present in a highly dispersed state on the carrier, and the smaller the metal crystal grains, the higher the specific surface area of the metal, and the higher the catalytic activity. For a particular carrier, there exists a critical value of grain size in relation to the loading of active ingredient, known as mono-layer dispersion, which can be determined by X-ray diffraction; when the carrying capacity exceeds the single-layer dispersion amount, the crystal grains grow gradually, the specific surface area is reduced, and the activity is reduced; therefore, when the loading amount exceeds 30 wt%, the crystal grains become very large, the activity is reduced to be close to that of bulk phase nickel, and the utilization rate of metal is not high; whereas at too low a loading, less than 0.1% (theoretically, the catalytic activity can be exhibited as long as nickel crystallites are present on the support), although the metal particles can be kept small, in practice the amount of active component available per unit mass of catalyst is small and the utilization of the support is not high, and therefore is not practical.
The preparation method of the catalyst comprises the following steps: loading nitrate of an active component on a carrier by adopting an isometric loading method, and directly activating and using a catalyst precursor loaded with the nitrate of the active component after vacuum dehydration at 100-140 ℃; or activating for use after vacuum roasting at 200-500 ℃;
the loading can be carried out by a normal pressure method or a vacuum method in one step or in steps; the vacuum method is preferably used for one-step impregnation loading; the catalyst precursor loaded with the nitrate as the active component is preferably directly activated for use after vacuum dehydration at 110-130 ℃; or preferably activated after vacuum roasting at 250-350 ℃.
The application conditions of the catalyst are as follows: in the presence of activated supported catalyst, at 40-100 ℃, using lower aliphatic alcohol as solvent and stoichiometric strong base as proton absorbent, at 1-15 x 105And (3) reacting under the pressure of hydrogen Pa.
The reaction temperature is preferably 60 to 70 ℃, and the strong base is preferably NaOH or Ca (OH)2As for the reaction medium, lower aliphatic alcohol, theoretically, as long as it can provide protons on hydroxyl groups, and has a low viscosity, it can be used as the reaction medium of the present invention to facilitate the sufficient dissolution and contact of various reactants, and methanol and isopropanol, for example, can be used as the reaction medium, and ethanol is preferred in view of toxicity, price, and the like.
The catalyst of the invention is used for catalytic hydrogenation degradation of organic halogenated aromatic hydrocarbon pollutants, and the reaction formula can be expressed as follows:
The invention has the following advantages:
1. low cost and good practicability.
