Definitions
- This invention relates to a novel method of generating hydrogen gas from water.
- Hydrogen is emergin as the favorite alternative to fossil fuels.
- hydrogen is primarily used as a feedstock, intermediate 10 chemical, or, on a much smaller scale, a specialty chemical. Only a small portion of the hydrogen produced today is used as an energy carrier, m ostly by the Aerospace industries.
- Automotive industries are developing new models that run on either hydrogen based internal combustion engines (ICEs), or gasoline - fuel cell cars.
- ICEs hydrogen based internal combustion engines
- 15 most of the commercial hydrogen production processes are not considered as renewable as these technologies merely shift the source of pollution from a distributed one (like cars, households for example) to a more concentrated source like a hydrogen producing plants or thermal power plants.
- the United States hydrogen industry alone currently produces nine million tons of hydrogen per year for use in chemicals production, petroleum refining, metals treating, and electrical applications.
- the electrolytic process is used worldwide for production of hydrogen gas. Currently, this method is used to produce high purity hydrogen. The cost of hydrogen produced using this method is significantly higher and hence, it is used only in specialty applications like semiconductor manufacture. But this method can facilitate more distributed hydrogen generation using electricity made from renewable and nuclear resources and will help to cater local requirements with oimitnuni distribution, and storage requirements [ 1]
- the primary by-product of this process is oxygen.
- Steam -methane reforming process is also used widely for the hydrogen production. In this catalytic process natural gas or other light hydrocarbons are reacted with steam to produce a mixture of hydrogen and carbon dioxide. The high-purity hydrogen is then separated from the product mixture.
- Partial oxidation of fossil fuels in large gasifiers is another method of thermal hydrogen production. It involves the reaction of a fuel wim a limited supply of oxygen to produce a hydrogen mixture, which is then purified. Partial oxidation can be applied to a wide range of hydrocarbon feedstock, including natural gas, heavy oils, solid biomass, and coal. Its primary byproduct is carbon dioxide. Emerging methods hold the promise of producing hydrogen without carbon dioxide emissions, but all of these are still in early development phases.
- therm o-chemical water-splitting using nuclear and solar heat photolytic (solar) processes using solid state techniques (photo- electrochemicaL, electrolysis), fossil fuel hydrogen production with carbon sequestration, and biological techniques (algae and bacteria).
- An object of this invention is to propose a novel method of producing hydrogen gas from water.
- Another object of this invention is to propose a novel method of producing hydrogen gas from water in presence of carbonaceous waste material and catalytic fluxes.
- Further object of this invention is to propose a novel method of producing hydrogen gas from water wherein molten slag is used for the thermo-chemical decomposition of water.
- Still further object of this invention is to propose a novel method of producing hydrogen gas from water which is simple and cost effective.
- mis invention there is provided a novel method for producing hydrogen gas from water comprising adding water to the slag and carbonaceous flux to produce hydrogen by thermo-chemical decomposition of water.
- Fig 1a shows the Effect of water addition on the concentration of FeO and Fe 2 O 3 in the slag and formation of H 2 gas, based on results of computation of Water - Slag phase equilibria at 1873 K.
- Fig 1b relates to a plot of enthalpy of water- slag system verses water addition, based on results of computation of Water - Slag phase equilibria at 1873 K. (b).
- Fig 2 shows the effect of water addition on the concentration of FeO and Fe 2 O 3 in the slag and formation of H 2 , CO and CO 2 gases computed using FACT-sage programme.
- Fig 3 shows the experimental set-up for hydrogen production.
- Fig 4 shows the line diagram and schematic of the set-up for hydrogen production in the slag pit at plant level.
- A is amount of water added in the system
- x is amount of C available in the flux
- y is FeO in the slag and z formation of CO 2 by 5 reaction between CO and water.
- slag not only provides sensible heat for endothermic water decomposition reaction but also arrest the reverse reactions between hydrogen and oxygen gas.
- the Fe and lower oxides of Fe in the slag react with oxygen gas in the product gas mix and form Fe 2 O 3 and thereby reduce the Io therm odynam ic activity of oxygen.
- Different types of wastes which can act as a deoxidizer, can be used as a flux to improve the production of hydrogen gas.
- the sensible heat of molten slag can be used for the thermo-chem ical 15 decomposition of water,
- slag acts as heat sources and some of the deoxidizing constituents (Fe, FeO) in the slag also take part in the decomposition reaction (1) by reacting with nascent oxygen via reaction (2):
- the exothermic oxidation reaction provides additional energy required for reaction (1) and also reduces the oxygen partial pressure of the system and thereby enhances the rate of formation of hydrogen gas.
- the phase equilibria data was computed for reaction between 100
- the carbonaceous and other plant wastes m aterials such as coal fines, coke breeze, etc. caa be used as deoxidizer which will enhance formation of hydrogen by therm o-chemical decomposition of water.
- the reactions between water and carbon are:
- the innovative devices (laboratory and plant) have been designed and fabricated for production of hydrogen gas using the steel plant slag as a heat source.
- the device designed can effectively harvest the product gas wim > 35% hydrogen using waste heat from slag.
- the condenser (6) and gas collection (11) tanks were first evacuated using vacuum pump (13), for removal of residual air and generation of negative pressure for flow of gas in the taaks.
- the system was isolated from surrounding by closing valves (6, 12) before experiment.
- the granulated slag from LD steel plant was melted in the induction furnace and superheated to ⁇ 1650 - 1700 C.
- the reaction hood (2) was then kept on the crucible.
- the controlled amount of water was sprayed on molten slag surface through water line (3).
- the product gases were formed by reactions between water, deoxidizers in the slag, and carbon from the crucible, as discussed in above sections.
- the product gas of me reactions was
- gas after removal / stripping of the steam was then collected in the gas collection tank (11) by opening the gas flow control valves (9, 10).
- the gas samples from condenser tank and gas collection tank were collected by connecting the gas sampler to the valves (9) and (12) respectively.
- the condensed water from the condenser tank (7) was
- the slag pot trolley in slag pit area the pot is removed from the trolley by overhead crane and slag is then poured in the slag pit. It takes about 2 days to fill the slag pit. Once pit is completely filled with slag, slag is cooled for some time and then it is quenched by spraying water jets from sides and top. It takes about a day to cool the slag in the pit.
- valve (19) was opened to remove the air and steam from the gas pipe line, once product gas with steam started coming out from the exhaust pipe of the blower (22), the valve (19) was closed and valve (6) was opened slowly.
- the product gas samples were collected by opening valve (5) and by connecting gas sampler.
- gas pressure in the tank reached + 800 mm (compound gauge (15) the gas valve (6) was closed and gas valve (19) was opened.
- reaction hood (2) was moved up samples were collected from condenser (7) and collection (11) tanks using samples ports connected to valves (17 and 18).
