Background technology
The energy is the important substance basis that the mankind depend on for existence and development, to the development and use of the energy from the past be that to turn to gradually in solid fuel epoch of master be master's the liquid fuel epoch with oil, hydro carbons etc. now with timber, coal.Yet it is, human more urgent to the demand of clean reproducible energy along with the soaring of oil price peters out with petroleum resources.Hydrogen Energy promptly is the clean renewable energy source that the low pollution of a kind of ideal or zero is polluted.Compare hydrogen with traditional fossil oil and have advantages such as aboundresources, recyclability, environment-friendly high-efficiency, can satisfy the needs of environmental resources and social economy's Sustainable development.As the important secondhand energy and the green energy resource in future, countries in the world all a large amount of input man power and materials study the exploitation and the application of Hydrogen Energy, and Hydrogen Energy also becomes more and more widely in the application of every field.
Hydrogen Energy is more at present as the desirable energy its preparation method in future, forms mainly containing of mass-producing: hydrocarbonaceous fossil oil reforming hydrogen manufacturing, water electrolysis hydrogen production etc.Remove photolysis water hydrogen, biological hydrogen production, thermochemistry hydrogen manufacturing etc. in addition in addition, though the not mass-producing at present of these class methods, the direction of representing the Hydrogen Energy new preparation technology to develop.At present, about in the world 95% hydrogen is to transform preparation through the hydrocarbonaceous fossil oil, and this wherein the technology of on the largest scaleization be Sweet natural gas steam reformation (CH
4+ H
2O → CO+3H
2), this process production technology is comparatively ripe, but energy consumption and production cost are all high, and facility investment is big, and product is carbon monoxide (CO) and hydrogen (H
2) mixed gas, as utilizing hydrogen (H wherein separately
2), just certainly will increase separation costs.Therefore cheap hydrogen manufacturing novel process or other hydrogen manufacturing new technology of research and development is significant.
Summary of the invention
For solving problems such as raw material resources are not enough, energy consumption is high, facility investment is big; The present invention provides a kind of oxygen carrier catalytic film to transform the method for water vapour continuous production hydrogen;, safety green, continuous, stable with realization response; Can solve the deficiency that prior art exists preferably, expand the source of Hydrogen Energy greatly, realize the environmental benefit maximization.
The present invention realizes through following technical proposal: a kind of oxygen carrier catalytic film transforms the method that water vapour is produced hydrogen, process the following step:
