full_question: Lithium iodide is used in the Celanese AO Plus process to drive down the rate of this reaction. In a different process, this side reaction is mitigated by the addition of a ruthenium tri-carbonyl tri-iodide promoter. The metallic copper catalyst for one step of this reaction is very vulnerable to sintering and poisoning from sulfur and halidesthese problems are partially mitigated by the addition of aluminum and zinc oxides. This is the main side reaction in both the Cativa and Monsanto processes. During one of the steps to this reaction, the hematite catalyst is reduced to magnetite while chromium oxide acts as a stabilizer. This reaction is usually performed in two reactors in series referred to as the "high temperature" and "low temperature" reactors. This reaction is typically performed after steam reforming of methane, where it converts the remaining syngas to hydrogen for use in methanol or ammonia synthesis. For 10 points, name this reaction which converts the namesake mixture of carbon monoxide and water to carbon dioxide and hydrogen.
