Abstract
The present invention, which discloses, a kind of prepares 1, the catalyst and its preparation method and application of 4- butynediols coproduction propilolic alcohol, the catalyst is based on the weight content of final catalyst, vector contg is 40 wt% ~ 70wt%, the content of copper bismuth zinc composite oxide is 30wt% ~ 60wt%, the copper bismuth zinc composite oxide is supported on carrier, and the carrier is at least one of SBA-15 molecular sieve, aluminium oxide, titanium oxide, molecular sieve, zinc oxide, zirconium oxide, silicon-containing alumina；The method for preparing catalyst use containing zinc, copper, bismuth solution impregnating carrier, final catalyst is made through drying and roasting after dipping.The advantages that active height of the catalyst, long-term operation stability is good, propilolic alcohol yield is high and preparation method is simple.
Description
Technical field
Isosorbide-5-Nitrae-butynediols coproduction propilolic alcohol catalyst and its preparation method and application, tool are prepared the present invention relates to a kind of
It says to body and is related to a kind of loaded catalyst and its preparation for preparing 1,4- butynediols coproduction propilolic alcohol for formaldehyde ethinylation
Methods and applications.
Background technique
Industrialized production Isosorbide-5-Nitrae-butynediols technique is mainly acetylene-formaldehyde process (Reppe method), domestic manufacturing enterprise Ru Shan
Western three-dimensional, Sichuan day China, Xinjiang Meike chemical industry, state's electricity Sinopec Ningxia derived energy chemical, Xingjiang Tianye Co., Inner Mongol gouy east, four
Chuan Weinilun factory etc. is all made of such technology.In the 1970s, develop the Reppe method technique of improvement, using slurry bed or
Suspension bed technique, reaction carry out under normal pressure or lower pressure.But Reppe technique is improved to catalyst and process condition
It is more demanding.In commercial plant, in order to avoid catalyst inactivation, reaction raw materials formaldehyde generally uses lower in reaction
Mass percentage concentration, due to the presence of water a large amount of in reaction solution, the copper ion of catalyst surface constantly by the flushing of water, compared with
It is easy to be flush with water.The catalyst of industrial application at present can all have a small amount of under normal handling conditions, in reaction solution
Cu2+In the presence of will lead to more Cu if operating condition slightly fluctuates2+It is lost, not only influences the activity of alkynes aldehyde reaction,
And Cu2+As reaction product flows into subsequent reactions workshop section, it is adsorbed on Ni-Al alloy catalyst surface, reduces nickel alumin(i)um alloy table
The quantity in the activated centre in face, to reduce the activity of catalyst.In addition, since Isosorbide-5-Nitrae-butynediols price in recent years is continuous
Decline, causes the profit of enterprise constantly to reduce, and propilolic alcohol causes its price to occupy high due to the continuous increase in downstream product market
Under not, so while producing Isosorbide-5-Nitrae-butynediols, the more propilolic alcohol of coproduction, the profit of enterprise is bigger.
US4110249 and US4584418 and CN1118342A is individually disclosed with DNAcarrier free malachite, carrier-free
Copper oxide/bismuth oxide catalyst, these catalyst are not wear-resisting, and metal component is easy to be lost.
US3920759 and CN102125856A is individually disclosed to be urged using zinc silicate, kaolin as the copper bismuth support type of carrier
Agent, for formaldehyde and acetylene reaction synthesis Isosorbide-5-Nitrae-butynediols catalysis reaction.But such catalyst has the disadvantage that
(1) carrier zinc silicate is unstable, can dissolve in the reaction system, the service life is short；(2) catalyst amount is more, metal copper oxide
Content is higher, easily reunites, and cannot give full play to the catalytic effect in each activated centre, causes the waste of copper resource.
CN201210157882.3 discloses a kind of copper bismuth catalyst and preparation method, and its step are as follows: using organosilicon
The alcoholic solution in source is added drop-wise in the mixed liquor containing mantoquita, bismuth salt, zinc salt and dispersing agent, and the pH of mixed solution is adjusted with aqueous slkali
Value obtains mixed sediment, through further aging, uses dispersing agent for the washing of medium progress sediment, and use inert atmosphere
It is roasted.The activity of the catalyst is higher, but higher cost, bad mechanical strength, it is difficult to realize industrialization.
CN201210397161.X is disclosed for Isosorbide-5-Nitrae-butynediols production catalyst and preparation method thereof, this method
Use nano silica for carrier, copper and bismuth are adsorbed on carrier by the method to precipitate deposition.The catalysis of the method preparation
Agent has preferable activity and selectivity, but due to using urea for precipitating reagent, reaction process is slower, can generate a large amount of ammonia
Gas causes environmental pollution.
CN103157500A discloses a kind of preparation method of loaded catalyst, and this method uses mesopore molecular sieve to carry
Body loads to soluble mantoquita and bismuth salt on carrier using infusion process, and the catalyst particle size of preparation is received for 10 ~ 80
Rice.CN103480382A disclose it is a kind of produce Isosorbide-5-Nitrae-butynediols catalyst and preparation method thereof, this method is using acidification
Nano silica afterwards is carrier, is adsorbed on copper and bismuth on carrier with dipping and deposition sedimentation method, then dry, roasting
Burn to obtain finished catalyst.Above-mentioned catalyst activity stability is to be improved.
In conclusion production Isosorbide-5-Nitrae-butynediols loaded catalyst is not high in the prevalence of activity in the prior art,
Especially long-term operation activity stability needs to be further increased, the propilolic alcohol of coproduction while producing Isosorbide-5-Nitrae-butynediols
Yield very little is insufficient.
Summary of the invention
It is an object of the invention to overcome above-mentioned defect existing in the prior art, provides and a kind of prepare Isosorbide-5-Nitrae-butynediols
The loaded catalyst and its preparation method and application of coproduction propilolic alcohol.The active height of the catalyst, long-term operation are stablized
The advantages that property is good, propilolic alcohol yield is high and preparation method is simple.
It is a kind of to prepare Isosorbide-5-Nitrae-butynediols coproduction propilolic alcohol catalyst, based on the weight content of final catalyst, carrier
