Description
Technical field
The present invention relates to a kind of chemical catalyst, especially relate to a kind of Preparation method and use of copper nickel compoilite oxide catalyst.
Background technology
Clorox (NaClO) is a kind of broad-spectrum raw material of industry, because it all has stronger oxidisability in acidity, weakly alkaline solution, is commonly used for disinfectant, bleaching agent; Liquor natrii hypochloritis is for the treatment of waste water, can reach the object of oxidation Decomposition pollutant, bleaching, sterilizing, deodorization, but in processing procedure, usually because clorox is unsettled compound, under higher or solar radiation, easily there is photolysis reactions in temperature, easily generate NaClO
3, NaCl, HCl etc., greatly reduce the utilization rate of clorox strong oxidizing property, the HCl gas producing in decomposable process has caused very large harm to environment simultaneously, strengthened again its oxidation susceptibility if generate environment amenable oxygen when clorox is decomposed, this will make this problem be settled properly.
Clorox is also the harmful side product of chlor-alkali plant, metallurgy industry, need to carry out nothing and poison processing.In chlor-alkali and metallurgy industry production, in tail gas gas, contain a large amount of chlorine, chlorine, as noxious material, need to carry out necessary processing before discharge, and conventional method is that the product of neutralization is clorox with the chlorine in sodium hydroxide solution and in waste gas at present.But the clorox generating often because low, the impurity content of concentration up to the value less than recycling, so in producing all waste liquid directly discharge.Clorox is because its unstability can generate the poisonous and hazardous material of environment, and simultaneously excessive clorox can produce carcinogenic substance chloroform in the aqueous solution, is industrial necessarily requiring so carry out resolution process.The general row acid decomposition of the generable isolation of clorox, thermal decomposition, light decompose and metal catalyzed decomposition.And clorox is met acid fast decoupled decomposition generation chlorine again.It is slow that thermal decomposition and light decompose decomposition rate, can not meet industrial demand, can produce environmentally harmful NaClO simultaneously
3.And catalytic decomposition can make clorox be decomposed into environment amenable sodium chloride and oxygen, be the optimal path of processing clorox problem so selective catalysis decomposes.Metal oxide has good catalytic effect to clorox, and the cartalytic decomposition effect of metal oxide (MeO) is as follows:
2MeO+NaClO＝Me
2O
3+NaCl
Me
2O
3+NaClO＝2MeO+NaCl+O
2
Although noble metal catalyst activity is higher, expensive, cost is high, is difficult to apply in actual production.The oxide of the metals such as manganese, copper, nickel has the effect of accelerated decomposition to clorox, be the ideal chose as catalyst.Nickel ion and copper ion and clorox can form good wrong fount, can realize the catalytic decomposition to clorox.But the oxide of independent copper and mickel needs higher temperature to the decomposition of clorox, and speed is slow, and efficiency is low, has limited its application.The decomposition reaction of clorox is one-level dynamic response, reduces temperature and concentration and can make the decomposition reaction velocity of NaClO slow down.And general in actual production what produce is the clorox of low temperature and low concentration, this requires catalyst to have and under low temperature, low consistency conditions, realizes fast decoupled feature.The composite oxide catalysts of copper and mickel can meet this requirement, and realize clorox fast, efficiently decompose.
Based on this, the present invention proposes a kind of composite oxide catalysts of copper and mickel, this catalyst has good catalytic performance, the effect that can make at low temperatures clorox reach fast, efficiently decompose.
Summary of the invention
