Abstract
The invention provides a transparent tubular reactor. The transparent tubular reactor is of a structural form in which a heating rod is embedded into a quartz outer tube for heating, and a reaction tube is a quartz tube and can be made of transparent materials such as hard glass. The heating rod and a thermocouple are sleeved with corresponding casings, and the casings are in the forms of blind tubes. The heating rod casing is inserted into the reaction tube from below the reaction tube, and quartz cotton and a catalyst are placed on the heating rod casing. The thermocouple casing is inserted into a catalyst from the upper part of the reaction tube, so that the thermocouple can be prevented from getting into direct contact with the heating rod. The flowing mode of gas is similar to a conventional tubular reactor, gas flows inwards from the upper inlet of the reaction tube, and a reaction product flows out of a bottom outlet. The reactor can be applied to the reaction research of the catalyst. In a reaction process, the color and state changes of the catalyst sample can be observed directly, so that the transparent tubular reactor has certain application value and application prospect.
Description
Technical field
The present invention relates in general to the instrument field of catalyst reaction performance test, is specifically to provide the visual fixed bed tubular reactor of a kind of outer tube transparent interior sample state.
Background technology
Fixed bed as a kind of conventional differential reactor device, is widely used in the sign of catalyst reaction performance.In real reaction process, the generation of catalytic reaction is accompanied by the change of catalyst color and state sometimes, that is to say, if we can observe the color of catalyst and the variation of state in course of reaction, there is change in the structure of this explanation catalyst, obviously this has obvious directive significance to the actual response state of our Study of Catalyst and catalytic reaction process in course of reaction.
The mode of the external heating furnace heating of the general employing of fixed bed now, reaction tube is in heating furnace, therefore in course of reaction, cannot observe color and the state of catalyst, thereby cannot judge that whether catalyst condition changes, and has limited the application of this reaction unit from sense organ.And the fixed bed reactors that can be observed reactor color and state there is not yet patent report, so the development and application of the visual transparent tubular reactor of catalyst seems extremely important, also very urgent.
Summary of the invention
The present invention has designed a kind of brand-new transparent tubular reactor, and considers emphatically the problem of existence in design.For example will consider that heating rod and temperature thermocouple insert in reaction tube, but both preferably will completely cut off mutually simultaneously, not be in contact with one another, the temperature of working sample, therefore carries out special design to the structure of this reactor so more accurately.Specifically, in the present invention, reactor is the version of the built-in heating rod heating of quartz outer tube, and reaction tube is transparent quartz ampoule material, also can adopt common hard glass or other transparent material.Heating rod and thermocouple all overlap and have corresponding heating rod sleeve pipe and thermocouple sheath outward, and the upper end of heating rod sleeve pipe and the lower end of thermocouple sheath are the form of blind pipe, so that the sealing of reaction tube.Heating rod sleeve pipe and heating rod insert in reaction tube below reaction tube, above heating rod sleeve pipe, place the certain thickness silica wool of one deck, on silica wool, place catalyst sample, heating rod heats catalyst by the mode of naturally conducting heat again, and makes the temperature of catalyst sample even.And thermocouple sheath and thermocouple insert in catalyst from reaction tube top, can prevent that like this thermocouple from contacting with the direct of heating rod, thermocouple contacts with catalyst in addition, can effectively measure the temperature of catalyst.The flow pattern of gas and traditional tubular reactor are similar, from reaction tube upper entrance, flow into, and after catalyst reaction, product flows out from reaction tube outlet at bottom.
Below in conjunction with accompanying drawing, be elaborated
Fig. 1 is the structural representation of transparent tubular reactor of the present invention;
As Fig. 1 structural representation that is transparent tubular reactor of the present invention.This transparent tubular reactor 1 is the version of built-in heating rod 8 heating of quartz outer tube 2, and reaction tube 2 is transparent quartz ampoule material, also can adopt common hard glass or other transparent material.The outer all covers of heating rod 8 and thermocouple 4 have corresponding heating rod sleeve pipe 7 and thermocouple sheath 3, and the lower end of the upper end of heating rod sleeve pipe 7 and thermocouple sheath 7 is the form of blind pipe, so that the sealing of reaction tube 2.Heating rod sleeve pipe 7 and heating rod 8 insert from below in reaction tube 2, heating rod sleeve pipe 7 is placed the certain thickness silica wool 6 of one deck above, on silica wool 6, place again catalyst sample 5, the rugosity of heating rod sleeve pipe 7 is suitable with reaction tube 2, therefore can play the effect of carrying silica wool 6, prevent from blowing in course of reaction or loose and cause catalyst sample 5 losses.Heating rod 8 heats the catalyst sample 5 supporting above by the mode of naturally conducting heat, and makes the temperature of catalyst sample 5 even simultaneously.And thermocouple sheath 3 and thermocouple 4 insert catalyst samples 5 from reaction tube 2 tops, can prevent that like this thermocouple 4 from contacting with heating rod 8, thermocouple 4 and catalyst sample 5 close contacts in addition, can measure the temperature of catalyst sample 5 effectively.The flow pattern of gas and traditional tubular reactor are similar, from reaction tube upper entrance 9, flow into, after catalyst sample 5 reaction, product flows out from 10 outlets of reaction tube bottom, enters in the detecting instruments such as chromatogram, mass spectrum, to analyze or emptying by carrying out after vent gas treatment.
Special construction due to this tubular reactor, in course of reaction, can observe directly the variation of catalyst sample color and state, for example, when the color of catalyst sample or state change, illustrate that catalyst sample changes in course of reaction, can tentatively judge according to the color of catalyst sample or state the variation of active specy in catalyst sample, the change color that for example transformation between the different valence state of noble metal causes, thereby the relation between the structure of associated catalyst sample and its reactivity worth to a certain degree.Moreover, catalyst is carried out to original position pretreatment, for example CuO reduction is processed and is generated 0 valency Cu, and the variation by color or state judges that whether preprocessing process is complete, and then catalyst can be used for further catalytic reaction or structural characterization.Therefore this transparent tubular reactor can, to a certain extent for the repercussion study of catalyst, have certain practical value and application prospect.
