The shift conversion reaction_________________?
Show answer Hide answer
Answer: B. Converts CO to CO2 with steam
Explanation
The shift conversion reaction utilizes steam to convert carbon monoxide into carbon dioxide and hydrogen. Water gas shift reactions adjust hydrogen to carbon monoxide ratios in syngas processing plants. Catalytic shift conversion plays a vital role in hydrogen production and ammonia synthesis preparation. Carbon monoxide reacts with steam over metal catalysts to produce carbon dioxide and hydrogen gas. The shift conversion process is moderately exothermic and operates in high-temperature and low-temperature stages. Equilibrium limitations require multi-stage reactor setups with intermediate cooling to maximize conversion.
Petroleum refineries use shift conversion units to maximize hydrogen yields for hydroprocessing operations. Ammonia production plants rely on shift reactors to remove carbon monoxide poisons from synthesis gas feeds. Clean energy technologies use water gas shift reactions to generate pure hydrogen for fuel cell applications. Option A describes nitrogen and hydrogen reacting to form ammonia, not the carbon monoxide shift reaction. Option C is false because shift conversion reactions require active metal catalysts like iron or copper. Option D is partially inaccurate because the reaction is mildly exothermic rather than extremely exothermic.
