Mn2O3-ZnO katalizatzailea metanolaren sintesirako, CO2-tik abiatuta hidrokarburoak ekoizteko bitartekari gisa

Abstract

The CO₂ capture and utilization processes are becoming increasingly important due to the progressive augment in greenhouse gases. In this work, the production of hydrocarbons from CO₂ in a single stage (with methanol as intermediate) was studied. Specifically, the Mn2O₃-ZnO catalyst for the synthesis of intermediate methanol was investigated. It was concluded that the optimal catalyst calcination temperature is 400°C. Moreover, it was proven that the catalyst works better in oxide state than in metallic state. Finally, regarding the influence of feed composition, better results were obtained in H₂+CO feeding than in H₂+CO₂ feeding due to water concentration in the reaction medium and to the higher reactivity of CO comparing to that of CO₂.
