Abstract

The present invention is catalyst for water vapor reformation of ethanol to prepare hydrogen and its preparation process and use. The catalyst is composite alumina and silica carrier supported Ni-Fe, Ni-Co, Ni-Cu, Ni-Zn, Cu-Zn, Cu-Co, Ni-Zr, NiO-LaOx, NiO-CeOx, NiO-YOx, NiO-MgOx or NiO-SrOx. It is prepared through the following steps: preparing catalyst carrier; compounding mixed solution of two kinds of nitrate; prepared turbid liquid of catalyst carrier; adding the mixed solution into the turbid liquid through stirring, evaporating water, stoving, grinding and baking. The catalyst has simple preparation process, low use temperature, high ethanol converting rate, and other advantages.

Description

technical field [0001] The invention relates to a catalyst, a preparation method and application, in particular to a catalyst for hydrogen production, a preparation method and the use of the catalyst for hydrogen production by steam reforming of ethanol, which belongs to the fuel cell hydrogen source technology. Background technique [0002] With the increasing global warming effect and the depletion of non-renewable resources such as petroleum, the disadvantages of fossil fuels have been paid attention to by various countries, and it is urgent to find a non-polluting green fuel that can replace petroleum. As a clean energy, hydrogen is attracting more and more attention. [0003] Hydrogen is an efficient, clean and renewable energy, which will play a significant role in the sustainable development of the global energy system and will have a huge impact on the global ecological environment. Hydrogen itself is renewable and when burned produces only water and no pollutants, ...
