Description
Technical field
The present invention relates to a kind of method of hydrogen, the present invention especially relates to a kind of method with preparing hydrogen by decomposing hydrogen sulfide.
Background technology
Shortage of energy sources has retrained expanding economy.Hydrogen is a kind of pollution-free combustible gas, and it is having a wide range of applications aspect industry, the Aeronautics and Astronautics etc.Up to the present, hydrogen mainly is to produce hydrogen as raw material, its complex process, inefficient shortcoming with fossil oils such as coal, oil, Sweet natural gases.
Summary of the invention
The method that the purpose of this invention is to provide a kind of hydrogen, this method comprises multinomial invention, overcome the problems referred to above of ordinary method, application present method scale operation at short notice goes out to have highly purified hydrogen, and cuprous sulfide is reusable after treatment (for example: copper).
In achieving the above object, comprise multinomial invention according to this method of the method that the invention provides a kind of hydrogen, as: the production of A. hydrogen sulfide, the decomposition of B. hydrogen sulfide, the desulfurization of C. cuprous sulfide.
The method that invention A hydrogen sulfide is produced, this method comprises uses raw material rosin, sulphur and catalyzer potassium permanganate, and rosin is exactly the resin of pine tree, its structural formula:
Its molecular formula C
19H
29COOH, it is just can directly be used by rosin removal impurity and moisture content, and sulphur can use the industrial sulphur powder, has the catalyzer potassium permanganate that accounts for rosin 2%-10% to exist down, rosin and sulphur mixture react the system hydrogen sulfide under 350-400 ℃ temperature, its chemical equation:
Since rosin, the physical properties difference of sulphur, and rosiny density is at 0.9-0.95g/cm
3Between, boiling point is about 360 ℃, and the density of sulphur is 2g/cm
3, boiling point is 444 ℃.Because rosiny density, boiling point are all little than sulphur, thus public fragrant heat respectively with sulphur after, again because of sulphur will on the temperature more than 360 ℃ could with the rosin rapid reaction. react in the rosin in that sulphur is from top to bottom dripped into.The quality of rosin, sulphur is calculated by following formula and is carried out adapted.
The method of invention B preparing hydrogen by decomposing hydrogen sulfide, this method comprise uses thin copper wire and hydrogen sulfide.Thin copper wire preferably uses diameter 0.1-0.15mm's.Hydrogen sulfide is removed sulphur steam through purifying, rosin steam and water vapor etc., 400---its chemical equation of reaction under 480 ℃ the temperature:
Wherein, the quality of copper use what calculate by chemical equation and carry out adapted.
The method of invention C cuprous sulfide desulfurization: this method comprises the use powdered rice hulls, the cuprous sulfide monolithic porous.
According to the method for this invention, at first on monolithic porous, keep flat the powdered rice hulls about one deck 0.5cm, cuprous sulfide is not directly contacted with high temperature heater (HTH).Below monolithic porous, heat then in that cuprous sulfide is placed on above the powdered rice hulls, when powdered rice hulls burns, make cuprous sulfide reach 500-600 ℃ of desulfurization and generate sulfurous gas and copper with airborne oxygen reaction.After the reaction beginning, the heat energy of emitting is proceeded till naturally cooling reaction.Make cuprous sulfide fully and burning rapidly, cuprous sulfide pulverized, in the cuprous sulfide powder, add some combustible fuel again, play its reactive chemistry equation of effect that ignites and be incubated as powdered rice hulls hybrid reaction powdered rice hulls and be:
If use high light, as tungsten lamp pipe reacting by heating, though very fast of reaction, cuprous sulfide that can only desulfurization 0.1-0.5cm, its reaction equation is:
The cuprous sulfide desulphurization reaction can not react in pure oxygen.
The industrialization desulfurization can be reelected a little and can use with the fluidizing furnace in the gas washing in SA production equipment.
Description of drawings
Accompanying drawing is the synoptic diagram according to preparing hydrogen by decomposing hydrogen sulfide Special Equipment of the present invention.
Embodiment
Sulphur is added sealing the molten sulphur device 2 from advancing sulphur mouth 3, again rosin 4 is added in the reactor 5, then molten sulphur device 2 is connected and seals with reactor 5.Again thin copper wire is put into sealing in the reactor 7, then reactor 5 and reactor 7 usefulness airways are coupled together and seal.Then all well heaters 8 are connect electrically heated.The sulphur of the heat fused hydrogen sulfide that reaction generates from the rosin 4 of porous plate 9 drippage heat fused is from pneumatic outlet 10 guiding cleaners 11, again by in the cleaner 11 directed response devices 7, in reactor 7, generate hydrogen with the thin copper wire reaction, derive hydrogen from pneumatic outlet 14, after water-cooled, can directly utilize.After reacting completely, again SO
215 feed the residual hydrogen sulfide of removal in the reactor 5 from the gas inlet.Then the resultant carbon in the reactor 5 is taken out.Again the cuprous sulfide of reactor 7 is taken out.Repeat to continue hydrogen according to above-mentioned method.
Embodiment
The production implementation method of invention A hydrogen sulfide according to the data proportioning that chemical equation calculates, is used rosin 250g to raw material sulphur, rosin, and sulphur 344.4g makes 530g hydrogen sulfide chemical equation:
The method of invention B hydrogen sulfide and copper reaction hydrogen is thin copper wire and invent the stink damp precursor reactant that A makes.Calculate with copper 1317.6g and hydrogen sulfide 350g reaction its chemical equation according to chemical equation:
Make 20gH
2
The data that the gas that makes according to the present invention and chemical equation calculate are variant, this be because of
Cause for incomplete reaction.
