What is methanol reforming process?

A methanol reformer is a device used in chemical engineering, especially in the area of fuel cell technology, which can produce pure hydrogen gas and carbon dioxide by reacting a methanol and water (steam) mixture.

Why is nickel a good catalyst?

2 Nickel Catalysts. Nickel-based catalysts are the most frequently used in reforming reactions due to C–C bond rupture capability. Nickel has been generally supported onto alumina because of its ability to withstand reaction conditions.

Which catalyst is used during the reaction of natural gas and steam?

nickel
The reaction bed in which natural gas steam reforming occurs normally contains a catalyst. This catalyst, mainly based on nickel, facilitates kinetic reactions (4.1) and (4.2), decreasing the reforming temperature. The main causes of catalyst deactivation are poisoning by sulfur and deposition of carbon.

How do you extract hydrogen from methanol?

To produce hydrogen from methanol at a low temperature (<100 °C), researchers recently invented some highly active and selective complex catalysts to catalyze methanol–water reforming at a low temperature (<100 °C) and produce high quality H2 with only a trace of, or even completely without CO.

What is the difference between SMR and ATR?

The difference between SMR and ATR is how heat is provided to activate the endothermic steam reforming reaction. In SMR, the catalyst is contained in tubes that are heated by an external burner. In ATR, a portion of the natural gas is burned to raise the temperature of the process gas before it contacts the catalyst.

What is Autothermal?

Definition of autothermal chemistry. : of, relating to, or being a reaction that creates synthesis gas using only the heat produced by the reaction itself One of the major advantages of thermophilic digestion (anaerobic and aerobic) is the ability to operate the digester under autothermal conditions.
