Utilization of CO_2 Via Catalytic Hydrogenation to Hydrocarbons - Kinetics, Selectivity and Process Considerations

摘要

Recycling of CO_2 from combustion processes in the form of hydrocarbons produced via the Fischer-Tropsch-synthesis takes advantage of the high value of hydrocarbon producets (e.g. as motor fuels or organic bulk products). In this paper results from an ongoing experimental and theoretical investigation are presented. Emphasis lies on thermodynamic and kinetic constraints of the synthesis reaction with CO_2, flexibility in product yield patterns, process implications and the analogy with CO as feedstock which is proven in numerous applications on a technical scale.
