Protective Gas Solution Methanol Cracking Hydrogen Generator By Advanced Technology

Protective Gas Solution Methanol Cracking Hydrogen Generator by Advanced Technology

Besides endothermic gas or endo gas, more and more methanol is used for the thermal treatment of metals as a protective gas. The methanol is directly inserted into the furnace and cracked there.
CH3OH → CO + 2 H2
Carbon monoxide and hydrogen are formed. The Methanol cracking gas is an excellent carrier gas.
Hydrogen and carbon monoxide are reducing agents and avoid oxidation or corrosion of metal surfaces in a furnace. It has to be taken into account, however, that carbon monoxide increases the carbon content of the steel. Methanol cracking gas can therefore be used for the surface hardening of steel by carbonization or carburization. Carbon concentration can be increased up to the saturation level of austenite in close surface areas (around 1mm deep).To control the carbonization, water vapor can be added or nitrogen can be used for dilution.

Figures:

1. The lowest hydrogen production cost (less than CNY18/Kg)
2. Low energy consumption – oil furnace design with no heat conduction
3. Smaller size – skid only need 20 m2 per 100Nm3/H
4. Safe and reliable – process is safe for hydrogen production from methanol reforming.

Applications:

1. With the reduction of photovoltaic power generation cost, the production cost of large scale alcohol is lower than that of coal to methanol, and the full cycle of zero carbon emission of alcohol hydrogen;
2. Effectively reducing the cost of hydrogen is an effective method to achieve the landing of fuel cell technology and form operation advantage;
3. It can be used as backup system and peak load balancing system of hydrogen generating unit;
4. More convenient and economical hydrogen source for hydrogen refueling stations.
