Abstract
The invention discloses a catalyst for producing hydrogen by reforming ethyl alcohol water vapor. A composition of copper oxide, zinc oxide and nickel oxide is loaded on a composite bearing base of aluminium oxide and silicon dioxide, and the composition comprises the following components in percentage by weight: 20% to 30% of copper oxide, 40% to 60% of zinc oxide and 20% to 30% of nickel oxide. The invention provides the catalyst for producing hydrogen by reforming ethyl alcohol water vapor, which is low in temperature, high in activity, high in selectivity and relatively low in cost.
Description
technical field
The present invention relates to a kind ofly for hydrogen production by ethanol steam reforming catalyst and manufacturing process thereof, belong to fuel cell hydrogen source technical field.
technical background
Day by day exhausted along with the non-renewable resources such as day by day serious and oil of global warming effect, fossil energy will be non-fossil energy replacement gradually.Wherein hydrogen production by ethanol steam reforming has unique superiority: (1) ethanol wide material sources, and biofermentation legal system ethanol raw material used can be regenerated; (2) ethanol is nontoxic, under normal temperature and pressure, is in a liquid state, and has the security on Storage and Processing; (3) energy of ethanol is far away higher than methyl alcohol and hydrogen; (4) ethanol has heat diffusivity on catalyst, and on highly active catalyst, ethanol is reformed and can in low temperature range, be occurred.The present invention will provide a kind of ethanol steam reforming catalyst that low temperature, high activity, high selectivity and price are cheaper that has.
Summary of the invention
The object of the invention is a kind of hydrogen production by ethanol steam reforming catalyst and manufacturing process thereof of being provided for, this catalyst has higher activity, and cheap.
For realizing above object, of the present invention a kind of for hydrogen production by ethanol steam reforming catalyst, be the composition that load has cupric oxide, zinc oxide and nickel oxide on alundum (Al2O3) and silica complex carrier.
The mass ratio of each component is cupric oxide 20%-30%, zinc oxide 40%-60%, nickel oxide 20%-30%.
A kind of preparation method for hydrogen production by ethanol steam reforming catalyst of the present invention, step is as follows:
(1) by Al (NO
3)
39H
2o joins rare HNO
3in, then add ethyl orthosilicate to mix, and forming gel, drying, roasting, make the catalyst carrier that aluminium silicon mol ratio is 1:1;
(2) nitrate of copper, zinc, nickel is water-soluble, add the urea of the 20-30% of total nitrate mass percent, after stirring, add said catalyst carrier, make dirty solution;
(3) by the isothermal reaction 6 hours at 100-110 ℃ of above-mentioned dirty solution, ageing 25h under normal temperature, filters, and evaporating water at 60-80 ℃ is dried, and grinds, and roasting 5-8h at 400-600 ℃, can obtain a kind of for hydrogen production by ethanol steam reforming catalyst.
The beneficial effect that the present invention produces is, it is cheaper that catalyst of the present invention has high stability, high activity, high selectivity and price, use catalyst of the present invention the reaction temperature of ethanol steam hydrogen production reaction can be reduced to 240 ℃, the conversion ratio that still guarantees ethanol is 100%, therefore can greatly reduce energy resource consumption.
Catalyst of the present invention, in preparation process, is made as 1:1 by the aluminium silicon mol ratio of catalyst carrier, can strengthen the performance of catalyst.Meanwhile, this catalyst only need, at lower roasting temperature, can reduce production costs.
