The success of the circular carbon economy will depend on the full range of technologies for converting CO2 and its derivatives into useful synthetic products using processes powered by low-carbon energy sources. CEA-Liten has put the circular carbon economy at the center of its research, most notably through the Carbon Conversion Platform. The platform has biomass conversion equipment for wood and agricultural and forest residues. It has other equipment that can be used to evaluate the potential of sources like household and industrial waste, solid recovered fuel, sludge from wastewater treatment plants, micro-algae, and food industry waste. The platform's test benches can be used to assess the performance of catalytic reactors for the conversion of gas mixtures including CO2 and/or CO by hydrogenation.
Finally, the platform is home to pilot manufacturing equipment and test benches for the development of thermoconversion processes and catalytic reactor technologies. The purpose is to scale up the following kinds of processes and technologies:
The platform also has laboratory-scale equipment used to develop models and understand reaction mechanisms. Finally the platform can analyze liquid and gaseous hydrocarbon products. The work carried out at the platform benefits from modeling and simulation for the development of conversion processes, analysis of test results, and system integration capabilities.
Industrial equipment manufacturer Leroux et Lotz Technologies turned to Liten, a CEA Tech institute, to design and build a complete sample collection and analysis system for gasification reactors. The system was installed on Leroux et Lotz’ test reactor in Nantes, France.
The REACSOL solar reactor developed by Liten, a CEA Tech institute, was successfully used for high-temperature biomass gasification in tests carried out in conjunction with lab CNRS-PROMES. The results of the tests—gasification of wood-based biomass continuously fed into the reactor with concentrated solar energy as the heat source—were encouraging.
The Génépi biofuel platform is open! Following three years of construction, most of the facility’s equipment is now operational. The platform is ready to innovate efficient biomass gasification methods to produce fuel.
