Question
This reaction is used to remove carbon monoxide from hydrogen sources for PEM fuel cells to prevent it from poisoning the platinum catalysts they contain. For 10 points each:
[10m] Name this reaction that converts carbon monoxide and water to hydrogen and carbon dioxide, often performed on syngas (“SIN-gas”) produced by steam reforming. It is also used to control the ratio of hydrogen to carbon monoxide in the Fischer–Tropsch process.
ANSWER: water–gas shift reaction [or WGSR]
[10h] The “sorption-enhanced” water–gas shift uses this process to remove carbon dioxide as the reaction progresses. This process uses changes in the eponymous quantity to alternately adsorb and desorb the target gas.
ANSWER: pressure swing adsorption [or PSA]
[10e] Another application of the water–gas shift and pressure swing adsorption is purifying hydrogen to prevent poisoning of the iron catalysts used in this industrial process, which synthesizes most of the world’s ammonia.
ANSWER: Haber–Bosch process
