Abstract
A process for preparing H2 by cracking, pyrolyzing and gasifying of water steam, CO2 and combustible substance includes such steps as adding combustible substance, lime stone and high-temp molten metal into smelting furnace, blowing O2, combustion to raise temp to 1400 deg.C, stopping the blowing of O2, blowing water steam from top, laterally blowing steam or the mixture of CO2 and combustible substance powder, combustion to heat the heat-exchanging tube cluster for generating steam, recovering fume, generating the mixture of H2 and CO2, separating H2 and recovering CO2.
Description
Technical field
The present invention relates to a kind of method that becomes hydrogen with water vapor, carbonic acid gas and combustible pyrolysis pyrolytic gasification.Belong to the Metal smelting technical field.
Background technology
At present, utilize generation biogas such as domestic waste, industrial or agricultural rubbish, coal drystone, coal to make fuel, or generate electricity and generation hydrogen with boiler combustion.Aforesaid method all exists investment big, takes up an area of defectives such as length big, consuming time, environmental pollution are serious.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of less investment is provided, speed is fast, and cost is low, and energy consumption is low, non-environmental-pollution, high efficiency become the method for hydrogen with water vapor, carbonic acid gas and combustible pyrolysis pyrolytic gasification.
The object of the present invention is achieved like this: a kind of water vapor of using, carbonic acid gas becomes the method for hydrogen with the combustible pyrolysis pyrolytic gasification, it is to be fuel with the combustiblematerials, water vapor, carbonic acid gas is a vaporized chemical, be equipped with lime masonry slag making desulfurization heat preserving agent, the pyritous molten metal is done carbon stablizer and efficient cracking pyrolysis agent, adopt furnace roof to blow water vapor, furnace bottom or furnace side are blown water vapor or are blown carbonic acid gas and the primary mixture of combustiblematerials powder, heat-exchanging tube bundle by top in the smelting furnace combustion heating furnace produces steam, flue gas reclaims the mixed gas that produces inflammable gas hydrogen and carbon dioxide
This method specific embodiment is: in smelting furnace, add combustiblematerials, Wingdale and pyritous molten metal, furnace bottom oxygen blast gas, burning, heat up, when stove Nei Wenduda is more than 1400 ℃, blow off oxygen, furnace roof blows water vapor, the primary mixture of furnace bottom or furnace side steam blowing or carbonic acid gas and combustiblematerials powder, the heat-exchanging tube bundle of top produces water vapor in the burning heating smelting furnace, reclaims the flue gas in the smelting furnace, produce the gas mixture of hydrogen and carbonic acid gas, separate this gas mixture, extract hydrogen, carbonic acid gas reuse to smelting furnace recycles.
The parts by weight of raw materials of each component is in the described smelting furnace:
80～100 parts of combustiblematerialss
3～5 parts in Wingdale
2～3 parts of iron and steel scrap liquid and ferromanganese liquid.
The present invention is without air, but utilize water vapor, carbonic acid gas and combustiblematerials to become the gas mixture of hydrogen and carbonic acid gas by Pintsch process, pyrolytic gasification, again through separation and Extraction hydrogen, carbonic acid gas circulating combustion, sufficient combustion, less investment, speed is fast, and cost is low, and energy consumption is low, non-environmental-pollution, high efficiency.
After tested, the present invention can be than traditional method energy-conservation 95～98%.
Combustiblematerials of the present invention is: straw, straw, domestic refuse, industrial refuse, coal drystone, coal etc.
Pyritous molten metal of the present invention is iron and steel scrap liquid and ferromanganese liquid.
Embodiment
Embodiment 1:
In smelting furnace, add the 98kg straw or/and straw, Wingdale 5kg and pyritous molten metal 3kg, furnace bottom oxygen blast gas, burning, heat up, when stove Nei Wenduda is more than 1400 ℃, blow off oxygen, furnace roof blows water vapor, furnace bottom or furnace side steam blowing or carbonic acid gas and coal drystone powder primary mixture, coal drystone powder consumption 2kg, the heat-exchanging tube bundle of top produces water vapor in the burning heating smelting furnace, reclaim the flue gas in the smelting furnace, produce the gas mixture of hydrogen and carbonic acid gas, hydrogen content 65% in the mixed gas, carbon dioxide content 32%.Separate this gas mixture, extract hydrogen, carbonic acid gas reuse to smelting furnace recycles.Common property is given birth to about 1000 cubes of hydrogen.
