Abstract: Proposed is a two-pot-two-step simultaneous conversion system for carbon dioxide and a hydrocarbon containing at least one hydroxy group and a method thereof. The system integrates a process of producing a metal salt that is a dehydrogenated form of the hydrocarbon, hydrogen, and water by reacting a hydrocarbon containing at least one hydroxy group in the presence of water and a metal oxalate, and a process of converting carbon dioxide or carbon dioxide-derived carbonate into formate by hydrogenation, thereby increasing energy efficiency while maintaining a higher hydrocarbon conversion rate and a higher carbon dioxide conversion rate than the one-pot conversion system for hydrocarbon and carbon dioxide.

Abstract: Provided is a process of manufacturing light olefins, which is a fluidized bed catalytic naphtha cracking process having improved economic feasibility and decreased greenhouse gas emissions. The process of manufacturing light olefins according to the present invention has a decreased hot spot occurring when supplying an additional fuel oil and decreased tendency of catalyst deactivation by water, thereby improving economic feasibility of the process and reducing greenhouse gas emissions to allow construction of an environmentally friendly process.
