A methane reformer is a device based on steam reforming, autothermal reforming or partial oxidation and is a type of chemical synthesis which can produce pure hydrogen gas from methane using a catalyst. There are multiple types of reformers in development but the most common in industry are autothermal reforming (ATR) and steam methane ...
Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is often hydrogen production , although syngas has multiple other uses such as production of ammonia or methanol .
Autothermal reforming Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form syngas. Auxiliary power unit An auxiliary power unit (APU) is a device on a vehicle whose purpose is to provide energy for functions other than propulsion. Availability factor

Syngas is produced by steam reforming or partial oxidation of natural gas or liquid hydrocarbons, or coal gasification. [6] C + H 2 O → CO + H 2 [1] CO + H 2 O → CO 2 + H 2 [1] C + CO 2 → 2CO [1] Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of methane: CH 4 + H 2 O → CO + 3 H 2

Chemical looping systems can directly be engaged as an effective means for syngas production. Compared to the conventional partial oxidation (POX) or autothermal reforming (ATR) processes, the key advantage of the chemical looping reforming (CLR) process is the elimination of the air separation unit (ASU) for oxygen production. The gaseous fuel ...
A membrane reactor is a device where oxygen separation, steam reforming and POX is combined in a single step. In 1997 Argonne National Laboratory and Amoco published a paper "Ceramic membrane reactor for converting methane to syngas" [3] which resulted in different small scale systems that combined an ATR based oxygen membrane with a water-gas shift reactor and a hydrogen membrane.
