Abstract
The invention discloses a method for cyclic production of hydrogen through decomposition of hydrogen sulfide gas. The method comprises the following steps: decomposing hydrogen sulfide into hydrogen and active sulfur at high temperature of 600-800 DEG C in the presence of a catalyst of chalcocite, and carrying out reaction on the generated active sulfur and rosin at the high temperature of 350-444 DEG C for generating the new hydrogen sulfide. The generated new hydrogen sulfide is re-decomposed for producing the hydrogen.
Description
Technology chin territory
The present invention relates to a kind of method of hydrogen, in particular, the present invention relates to a kind of cyclic production of hydrogen through decomposition of hydrogen sulfide of using.
Background technology
The health of the harmful human body of the pollution of environment, hydrogen process of the present invention is without any deleterious gaseous emission.Hydrogen be a kind of free of contamination clean fuel it on fortification industries, use as aspects such as space flight, chemical industry, so far, the raw material of hydrogen is that the fossil oil of coal, oil, natural gas etc. comes hydrogen as raw material, and obnoxious flavour is discharged in process of production, complex process, the shortcoming that effect is low.
Summary of the invention
The objective of the invention is to encircle a kind of method of cyclic production of hydrogen through decomposition of hydrogen sulfide, this method has overcome the above-mentioned problem of conventional method, use this law have sufficient rosin just all over the city the city the needs of useful hydrogen, raw material sulphur recycles and does not consume.
In achieving the above object, put forward the method for having encircleed a kind of cyclic production of hydrogen through decomposition of hydrogen sulfide according to the present invention, this method comprises uses raw material rosin, hydrogen sulfide, catalyzer copper glance.The road was gone into to be heated in the 600-800 ℃ of catalyzer copper glance reacting to generate hydrogen and active sulphur after the preparation of purified hydrogen sulfide was heated to 600 ℃.The hydrogen of generation and active sulphur will keep 444-500 ℃ not react generation hydrogen sulfide once more again, and pyritous hydrogen and active sulphur import active sulphur and the new hydrogen sulfide of rosin reaction generation in the rosin that is heated to 150 ℃, its chemical equation;
Press above-mentioned method isolated newly-generated hydrogen sulfide circulating reaction hydrogen successively.
Above-mentioned rosin is the resin of a kind of plant pine tree, and the impurity of the rosin elimination Folium Pini that cuts out from the pine tree trunk etc. is just directly made raw material and used.The major ingredient of copper glance is (CU
2S), make catalyzer with copper glance and earlier the just straight use of assorted stone is removed in caked copper glance pulverizing.The active sulphur and the reaction of the rosin (2) formula that generate from the identical decomposition with (3) formula of above-mentioned equation (1) formula generate new hydrogen sulfide.Do not consume sulphur by this method cyclic production of hydrogen through successively, the structural instability of hydrogen sulfide just begins to decompose for about 300 ℃, with copper glance do catalyzer in the rate of decomposition of 600-800 ℃ of decomposing hydrogen sulfide by with what kilogram copper glance, how long hydrogen sulfide passes through the pyritous copper glance, just high more by the rate of decomposition of time hydrogen polysulfide.
Description of drawings is according to cyclic production of hydrogen through decomposition of hydrogen sulfide Special Equipment synoptic diagram of the present invention.
Specific embodiment
Pure hydrogen sulfide is led to into heating the splitter 2 from 1, import the reaction of 4 rosin containers from 2 importing hydrogen and active sulphur mixture again, charcoal, hydrogen, water, the hydrogen sulfide of active sulphur in the mixture and the rosin complete reaction resultant in the splitter, hydrogen sulfide, hydrogen, water are discharged from exporting 5, after open switch 6, rotate 120 ° then and scratch millstone and scratch broken solid-state charcoal, broken charcoal is discharged from 6 outlets.
Embodiment
The production implementation method of invention cyclic production of hydrogen through decomposition of hydrogen sulfide.The data proportioning that raw material hydrogen sulfide, rosin calculate according to chemical equation, use 1 kilogram in hydrogen sulfide, 0.682 kilogram of rosin.Chemical equation;
Make 0.08 kilogram of hydrogen.The data that hydrogen gas that makes according to the present invention and chemical equation calculate are difference to some extent, is because the cause of plant issue and incomplete reaction.
Claims (3)
1. method with cyclic production of hydrogen through decomposition of hydrogen sulfide, this method comprises uses hydrogen sulfide to have the catalyzer copper glance to generate hydrogen and active sulphur at 600-800 ℃ pyrolytic decomposition, the active sulphur semi-annular jade pendant that generates generates hydrogen sulfide 350-444 ℃ high temperature and rosin reaction, isolates hydrogen simultaneously.
2. according to the method for claim 1, rosin will separately be heated to 150 ℃ temperature.
3. according to the method for claim 1, hydrogen and active sulphur semi-annular jade pendant that hydrogen sulfide decomposes will remain on 444-500 ℃, and the hydrogen of decomposition and active sulphur semi-annular jade pendant be secondary response no longer, help the reaction of active sulphur semi-annular jade pendant and rosin and generate new hydrogen sulfide.
