Embodiment Construction

[0024] The following examples will further illustrate the present invention, but do not limit the present invention thereby.

[0025] Catalytic combustion reactor for removing hydrogen in tail gas of the present invention ( figure 1 ), mainly including a catalytic combustion main area (1a) and two different heat exchange areas (1b and 1c). There are three cavities from the center to the outside, which are: catalytic combustion chamber (1a), combustion tail gas heat exchange chamber (1b) and hydrogen-containing tail gas heat exchange chamber (1c). First, a certain amount of air and the exhaust gas to be treated are respectively introduced into the reactor inlets (11) and (12), and the exhaust gas passes through the hydrogen-containing tail gas heat exchange chamber (1c), and then passes through the hydrogen-containing tail gas heat exchange chamber (1c) and the internal connecting channel (13) of the catalytic combustion chamber (1a) enters the catalytic combustion chamber (1a...

Abstract

The invention relates to a catalytic combustion reactor and process for removing hydrogen in tail gas. The reactor comprises three cavities from center to outer sides. The center of the reactor is filled with catalyst for catalyzing the chemical reaction of gas containing hydrogen and the air, so that catalytic combustion reaction of the tail gas containing the hydrogen and the oxygen in the air by the aid of the catalyst without heating and pressurizing, and the hydrogen can be removed. The reactor is widely applicable to hydrogen removing of the industrial tail gas, also capable of removing CO and reducing substances such as alcohol like methyl alcohol and ethyl alcohol and hydrocarbons in the tail gas, and especially suitable for processing the anode tail gas of fuel batteries.

Description

technical field [0001] The invention belongs to the technical field of catalysis, and in particular relates to a catalytic combustion reactor and a process for removing hydrogen in tail gas. Background technique [0002] A fuel cell is a power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy through electrode reactions, with high energy conversion efficiency and low environmental pollution. Since the 1990s, proton exchange membrane fuel cell technology has developed rapidly and has entered the early stage of commercialization. It is especially suitable for mobile power sources, backup power sources and distributed power stations. In the 21st century, proton exchange membrane fuel cells will be rapidly applied and become a new industry. [0003] The ideal raw material for proton exchange membrane fuel cells is pure hydrogen. In theory, as long as hydrogen is continuously supplied to the anode of the proton exchange me...
