Technical field:
The present invention relates to catalyst technical field is and in particular to a kind of double-component alkynes catalyst for hydrogenation.
Background technology:
During hydrocarbon cracking alkene, generating ethylene, propylene, butylene and butadiene produce part alkynes simultaneously and Alkadienes.It is objectionable impurities that these alkynes and alkadienes are processed particularly in olefin polymerization process after alkene, needs to remove.Choosing Selecting hydrogenation and being allowed to become corresponding monoolefine is most economical and the most received method.Wherein, selective hydrogenation catalyst Using very crucial, need catalyst to have good selectivity, only monoolefine is not lost to alkynes and diene hydrogenation;And And catalyst will have good activity, reacts at a lower temperature, reduce and by olefin(e) oligomerization, catalyst is polluted, and Catalyst is led to inactivate.
Content of the invention:
The technical problem to be solved is to provide that a kind of selectivity is strong, activity is high and double groups of long service life Part alkynes catalyst for hydrogenation.
The technical problem to be solved to be realized using following technical scheme:
A kind of double-component alkynes catalyst for hydrogenation, by the first component catalyst than 3:1 for the weight and component B catalyst Composition, described first component catalyst using ceramic as carrier, active component based on palladium, copper be help active component, wherein Palladium accounts for the 10-15% of total weight of carrier, and copper accounts for the 3-5% of total weight of carrier;Described component B catalyst oxygen than 2:1 by weight Change chromium and phosphorus pentoxide mixes.
The preparation method of described first component catalyst is: Palladous chloride., copper chloride and potassium chloride are mixed by weight 2:1:0.5 Add water after conjunction and be made into the impregnation liquid of mass concentration 20-30%, and add the ceramic of 3-5 times of Palladous chloride. weight, fully dispersed Afterwards stand 30min, microwave treatment 5min under microwave frequency 2450mhz, power 700w, process terminate after under ice-water bath with The speed of 10 DEG C/min is lowered the temperature, and continues after temperature is down to 35-45 DEG C under microwave frequency 2450mhz, power 700w Microwave treatment 3min, then naturally cools to room temperature, and gained mixture is sent in freezer dryer, becomes through abundant crushed after being dried Powder, finally by gained powder at 450-500 DEG C roasting 3h.
Using front through pretreatment, its processing method is described ceramic: first adds equivalent to mix 20 parts of ceramics Close in solution, by weight, the Oleum Terebinthinae than 1:1 is mixed, fully this mixed solution with the dilute nitric acid solution of mass concentration 40% Moistening stands 3h at 0-5 DEG C, and supersound process 15min under supersonic frequency 40khz, power 100w, is subsequently adding 1.5 parts Spermol and 1 part of silane coupler, mix homogeneously microwave treatment 5min, mistake under microwave frequency 2450mhz, power 700w Filter, gained filtering residue is dried 8h prior to 100-110 DEG C, then at 500-550 DEG C of roasting 2h, last grind into powder.
The invention has the beneficial effects as follows: the present invention adopts double-component form that alkynes catalyst for hydrogenation, this catalysis are obtained Agent is high to the hydrogenation selectivity of alkynes and alkadienes, substantially reduces the loss amount of monoolefine;And catalysis activity is strong, can will be hydrogenated with Reaction temperature reduces by more than 50 DEG C, thus reducing pollution catalyst being caused by olefin(e) oligomerization, extends the use longevity of catalyst Life.
Specific embodiment:
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, tie below Close specific embodiment, the present invention is expanded on further.
The preparation of first component catalyst: 2g Palladous chloride., 1g copper chloride and 0.5g potassium chloride are added water and is made into mass concentration 30% impregnation liquid, and add 6g ceramic, fully dispersed rear standing 30min, then at microwave frequency 2450mhz, power Microwave treatment 5min under 700w, process is lowered the temperature with the speed of 10 DEG C/min after terminating under ice-water bath, treats that temperature is down to 35- Continue microwave treatment 3min under microwave frequency 2450mhz, power 700w after 45 DEG C, then naturally cool to room temperature, gained Mixture is sent in freezer dryer, becomes powder through abundant crushed after being dried, finally by the roasting at 450-500 DEG C of gained powder 3h.
After testing, palladium accounts for the 12.67% of total weight of carrier, and copper accounts for the 3.95% of total weight of carrier.
Component B catalyst is mixed by the chromium oxide than 2:1 for the weight and phosphorus pentoxide.
First component catalyst is sufficiently mixed than 3:1 with weight with component B catalyst, that is, double-component alkynes hydrogenation is obtained Catalysts.
The pretreatment of ceramic: first add 20g ceramic in mixed in equal amounts solution, this mixed solution is by weight ratio The Oleum Terebinthinae of 1:1 is mixed with the dilute nitric acid solution of mass concentration 40%, and abundant moistening stands 3h at 0-5 DEG C, and in Supersound process 15min under supersonic frequency 40khz, power 100w, is subsequently adding 1.5g spermol and 1g silane coupler, and mixing is all Even microwave treatment 5min under microwave frequency 2450mhz, power 700w, filters, gained filtering residue is prior to 100-110 DEG C of drying 8h, then at 500-550 DEG C of roasting 2h, last grind into powder.
