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 ...
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.
Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form syngas. The reaction takes place in a single chamber where the methane is partially oxidized. The reaction is exothermic. When the ATR uses carbon dioxide, the H 2:CO ratio produced is 1:1; when the ATR uses steam, the H 2:CO ratio produced is ...
As of 2020, estimated costs of production are $1–1.80/kg for grey hydrogen and blue hydrogen, [177] and $2.50–6.80 for green hydrogen. [ 177 ] 94 million tonnes of grey hydrogen are produced globally using fossil fuels as of 2022, primarily natural gas, and are therefore a significant source of greenhouse gas emissions.
The test plane, a newly liveried ATR 72-600 aircraft with a hydrogen retrofit kit, will soon begin taking to the skies. A JetBlue-Backed Hydrogen-Fuel Powered Airplane Is Coming to the US for ...
Hydrogen is a chemical widely used in various applications including ammonia production, oil refining and energy. [1] The most common methods for producing hydrogen on an industrial scale are: Steam reforming, oil reforming, coal gasification, water electrolysis. [2] Hydrogen is not a primary energy source, because it is not naturally occurring ...
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 ...
