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 and a preparation method and use thereof, in particular to a catalyst for hydrogen production, a preparation method and the use of the catalyst for ethanol steam reforming to produce hydrogen, belonging to fuel cell hydrogen source technology. Background technique [0002] With the increasing global greenhouse effect and the depletion of non-renewable resources such as oil, the disadvantages of fossil fuels have been paid attention to by all countries. It is urgent to find a pollution-free green fuel that can replace oil. As a clean energy, hydrogen is attracting more and more attention. [0003] Hydrogen is an efficient, clean, and renewable energy source. It will play a significant role in the continuous development of the global energy system and will have a huge impact on the global ecological environment. Hydrogen itself is renewable, only water is produced when it is burned, no pollutants, or even CO 2 , Can achieve...
