Set-up for production of hydrogen gas by thermo-chemical decomposition of water using steel plant slag and waste materials |
摘要 |
A system for the production of hydrogen from water in the presence of slag, comprising a graphite crucible containing molten slag; a reaction hood disposed over said crucible; a water line for spraying water on the molten slag in the crucible; and a steel tube for collecting and transferring the produced hydrogen gas from said hood into a condenser tank. |

1. A system for the production of a gas stream comprising hydrogen, the gas stream containing greater than 30% hydrogen by volume with less than 10% carbon monoxide by volume when adding water and carbonaceous flux, such that an H2O:C ratio by weight is 10:1, to molten slag containing FeO, the system comprising:
a graphite crucible or slag pit; FeO-containing molten slag in the graphite crucible or slag pit, wherein FeO is a deoxidizing constituent for reacting with oxygen to form Fe2O3 for preventing a reverse reaction between hydrogen and oxygen gas; a reaction hood disposed over said crucible or slag pit, wherein the reaction hood isolates a reaction space under the reaction hood from the surrounding atmosphere; a water line for spraying water on the FeO-containing molten slag in the crucible or slag pit to produce hydrogen gas by the decomposition of water; and a tube for collecting and transferring a gas stream containing greater than 30% hydrogen by volume with less than 10% carbon monoxide by volume from said hood into a condenser tank; wherein the collected hydrogen gas is passed to a gas collection tank via at least one control valve. |
