Description
Technical field
The invention belongs to biochemical test chamber device, specifically refer to a kind of catalytic activity determinator.
Background technology
Desulfurization is that Containing Sulfur chemical product is as requisite technological process in crude oil processing, as the development of hydrodesulfurizationprocess process has become worldwide heat subject, the catalyzer of the various trades mark appears on the market in succession, the activity of catalyzer is the focus that researcher and user very pay close attention to, but the difference due to assay method, same catalyzer has various result, directly has influence on the application and development of catalyzer; On market, disclose a kind of Standard Program For Activity Test of Hydrodesul Phurization Catalyst, comprised Kaolinite Preparation of Catalyst, catalyst activity determinator is set, catalyzer weighing, catalyzer pre-service, determination of activity, calculating; The data that finally obtain evaluating catalytic activity are for comparison reference; The catalyst activity determinator use cost that it adopts is higher, relatively complicated, is not easy to laboratory operation, thereby is necessary to carry out on this basis innovative design.
Summary of the invention
The object of this invention is to provide catalytic activity determinator.
Technical scheme of the present invention is achieved in that
Catalytic activity determinator is provided, comprises a three-necked bottle, it is characterized in that: one of them open communication base buret endpiece of described three-necked bottle, the entrance point of described base buret is communicated with catalyzer separating funnel; One of them opening of described three-necked bottle also connects oxygen bottle by two-way valve A, so that mensuration source of oxygen to be provided; Described three-necked bottle bottom is placed in water-bath, and described water-bath is placed on magnetic stirring apparatus, is convenient to the liquid in three-necked bottle to stir; One thermometer is set, and its lower end is placed in water-bath, for measuring the temperature of water-bath; Described thermometer is suspended on an iron stand.
The determinator of catalytic activity as above, is characterized in that: one of them opening of described three-necked bottle is communicated with base buret and oxygen bottle by the two-way control of two-way valve B.
The determinator of catalytic activity as above, is characterized in that: one of them opening of described three-necked bottle is also provided with a gas outlet, is also provided with two-way valve C on described gas outlet.
Below, provide and utilize device of the present invention to carry out catalytic activity method for measuring:
Refer to Fig. 1, according to Fig. 1, connect apparatus of the present invention, fix separating funnel;
1, open two-way valve A, B, C, in separating funnel, add appropriate water, make the liquid level in base buret rise to 0ml parallel with the liquid level in separating funnel, then close two-way valve C, open the logical oxygen of oxygen bottle reduction valve and two-way valve A;
2, in base buret, liquid level drops to scale 50ml left and right, opens two-way valve C;
3, in base buret, liquid level rises to scale 0ml left and right, closes two-way valve C;
4, emptying air after repeating step 2 and 3, five times, static 5 minutes, makes system temperature constant in (40 ℃ of summer, autumns, 35 ℃ of spring, winters);
When 5, liquid level is static in base buret, read the volume (injection front volume) in base buret now, pour appropriate 0.05mol/L sodium sulfide solution in porcelain crucible, with syringe, suck 5ml, from three-necked bottle injection port K1, inject.Use the same method, get another syringe and suck 5ml desulfurization catalyst solution (liquid to be measured), from three-necked bottle injection port K2, inject.Start stirrer and carry out timing, read rapidly base buret initial volume (volume after injecting), every 1 minute, read No. one time base buret volume later, and find corresponding volume from the volume table of comparisons (showing attached).When liquid level no longer rises, reaction stops; Recorded test result, temperature of reaction, closes stirrer.
Please note when changing test solution, must first close two-way valve B, then open two-way valve C, then open three-necked bottle opening stopper.
Desulfurization catalyst activity is calculated as follows:
CA=?V2－V7／5×10
In formula: the activity of CA-desulfurization catalyst (every ml soln per minute absorbs the milliliter number of oxygen).ml·min-1?ml-1
When starting latter second minute, V2-reaction finds corresponding volume from the volume table of comparisons.ml
The corresponding volume of finding from the volume table of comparisons when V7-reaction starts latter the 7th minute.ml
Points for attention:
1, the sodium sulfide solution of preparation, the term of validity is 1 week.
While 2, carrying out parallel experiment, whole operating system remains under equivalent environment and condition as far as possible carries out, to reduce test error.
Structural reduction of the present invention, easy to operate, be adapted to laboratory environment, equipment is easy to get, less investment, measuring accuracy is high, for the mensuration of desulfurization catalytic activity provides a kind of utility unit.
