How does an autothermal reformer work?

Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form synthesis. The reaction takes place in a single chamber where the methane is partially oxidized. The reaction is exothermic due to the oxidation.

What is Autothermal operation?

Autothermal operation combines energy-absorbing and energy- releasing chemical reactions to control the temperature of a chemical reactor instead of removing or adding heat. Eliminating heat transfer simplifies reactor design and reduces costs.

What is ethanol reforming?

Reforming of ethanol to produce hydrogen is a potentially attractive process. The reactions involved include steam reforming followed by water-gas shift and selective oxidation of CO. The development of suitable catalysts for these reactions is crucial for the viability of the process.

How is methanol converted into hydrogen?

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 an autothermal reactor?

Autothermal Reforming (ATR) is a process for producing syngas, composed of hydrogen and carbon monoxide, by partially oxidizing a hydrocarbon feed with oxygen and steam and subsequent catalytic reforming.

What is autothermal reforming?

Autothermal Reforming (ATR) is a process for producing syngas, composed of hydrogen and carbon monoxide, by partially oxidizing a hydrocarbon feed with oxygen and steam and subsequent catalytic reforming.

What is the suitable fuel for autothermal reforming?

The suitable fuel for autothermal reforming is highly flexible, such as several gaseous hydrocarbons, e.g., methane, natural gas, LPG, as well as liquid hydrocarbons, e.g., gasoline, diesel, alcohols, naphtha, residual oil, ethylene glycol, and glycerol.

What is the difference between steam reformer and autothermal reformer?

The steam reformer requires external combustion to provide heat for the endothermic reforming reactions, whereas the autothermal reformer requires high purity oxygen within the reactor to facilitate internal combustion. Each reformer can operate at three discrete temperature (SMR: 800 °C, 850 °C, or 900 °C, ATR: 900 °C, 950 °C, or 1000 °C).

What is autothermal hydrogen rejuvenation?

Autothermal reforming, which is the combined process of steam reforming and partial oxidation, is a promising technology for low-cost and high-reliability hydrogen production.
