CO AND CO2 HYDROGENATION BY FISCHER TROPSCH SYNTHESIS PROMOTED WITH IRON BASED HETEROGENEOUS CATALYSIS: DATA COLLECTION AND PROCESS DESIGN
type: CreativeWork
description: The reduction of CO2 emissions into the atmosphere has become a global priority, given the crucial role of this greenhouse gas in climate change. A promising approach to mitigate CO2 is its conversion into fuels and chemicals through processes such as Fischer–Tropsch (FT) synthesis. Traditionally, FT relies on syngas (CO/H2) over transition-metal catalysts, but the direct hydrogenation of CO2 has been less explored, particularly with Fe-based heterogeneous catalysts. Iron is an abundant and inexpensive metal, already known for its high activity in conventional FT from CO. This research aims to develop novel Fe-based catalysts effective in both CO and CO2 derived FT, while also addressing the interconnected challenges of environmental sustainability, operational safety, and predictive process modelling. The ultimate goal is to provide a holistic solution for upgrading CO2 into hydrocarbons, bridging existing gaps in the development of materials (e.g., Fe-based metallosilicates and hydrotalcites) that have been scarcely investigated to date. To this end, innovative iron-based catalysts were synthesized, tested under CO and CO2 FT conditions, and evaluated through Life Cycle Assessment (LCA), HAZOP/LOPA safety analysis, and artificial intelligence tools (artificial neural networks) for performance optimization. This integrated approach provides a comprehensive perspective on CO/CO2 conversion, representing an important step toward the practical implementation of Carbon Capture and Utilization (CCU) technologies. Two main classes of Fe-based heterogeneous catalysts were investigated: (1) mixed oxides derived from hydrotalcites (e.g. Mg-Fe-Cu), synthesized via ultrasound-assisted co-precipitation (US) and, in some cases, subjected to ball milling (BM), and (2) iron catalysts supported on mesoporous metallosilicates, synthesized by non-hydrolytic sol-gel routes. All catalysts were promoted with potassium and copper, both known to enhance activity and selectivity toward he…
