Plasma catalyzing process of preparing hydrogen by ammonia decomposition

Abstract

A plasma catalysis process for preparing H2 by decomposing ammonia at lower temp to obtain the H2-N2 mixture used for the proton exchange membrane type fuel battery of car features that the non-noble-metal carried catalyst, whose active component is chosen from Fe, Co, Ni, Cr, Mo, Mn, Cu and W, is loaded in the discharge region in a plasma catalytic reactor.

Description

technical field

[0001] The invention belongs to the technical field of plasma chemistry and hydrogen energy, and relates to a hydrogen-nitrogen mixed gas that can decompose ammonia gas at a relatively low temperature, which is beneficial to the use of proton exchange membrane fuel cell vehicles and does not contain carbon monoxide and carbon dioxide. method. Background technique

[0002] The increasing depletion of fossil energy such as coal, oil and natural gas, and the serious environmental pollution caused by the direct use of these fossil energy forces people to continuously improve the efficiency and cleanliness of energy use. It is against this background that the development and application of hydrogen energy has received more and more attention from countries all over the world.

[0003] Hydrogen energy can be converted into electricity using a proton exchange membrane fuel cell (PEMFC). What happens during this conversion is a battery reaction of hydrogen and oxyg...
