Recently, the use of molten-metal bubble column reactors (MMBCRs) has increased rapidly since they touch upon many hot research topics such as cleaner and cheaper hydrogen production, and the degradation of greenhouse gases to produce valuable solid products as well. Researchers usually prefer the development of a catalyst to increase the process efficiency. However, the price, toxicity, and deactivation of the catalyst are open questions. Another way to solve this problem is the use of intermediate chemicals to react with gases to produce separable products [1, 2]. This may open a gate for innovation in separation and purification technology. How do you think about that?
