CO₂ & H₂ - eFuels

The decarbonization of industries that emit large amounts of CO₂, such as cement, steel, incinerators, pulp and paper, biomass boilers, refineries, and chemistry, can be addressed by capturing and converting the CO₂ into renewable or low-carbon fuels.
This process relies heavily on low-carbon electricity (used to produce hydrogen), which is then mixed with CO₂.
As a result, the final life cycle analysis of these fuels shows a lower carbon footprint. This approach offers a solution for decarbonizing the transportation sector, including maritime, aviation, and both light and heavy-duty vehicles.

Axens offers a comprehensive range of technologies, including Carbon Capture (DMX™, Advamine™), Reverse Water Gas Shift (Carboverseo™), CO₂ conditioning, H₂ purification, Fischer Tropsch, and Upgrading (Gasel®), to convert CO₂ into renewable/low-carbon fuels at low operating cost.
Furthermore, the more stringent specifications are met with a diverse range of products allowing the purification of CO₂, Syngas and H₂. The RWGS and Fischer Tropsch catalysts are protected against poisoning and deactivation.
The bankability of your project is guaranteed through a single point of contact, strong research and development support, and integrated guarantees.

CO2 Gas Drying

The dehydration of CO2 streams presents specificities such as corrosiveness, acid gases co-absorption and TEG recovery. Consequently, for decades, it has been seen as a challenge for the operators. This stands true in various industries and particularly in the oil&gas sector, whether on highly sour natural gases or on pure CO2 streams for enhanced oil recovery (EOR) purpose.

DMX™

The DMX™ process, a patented process stemming from IFPEN’s Research and marketed by Axens, is a second-generation process using a solvent that reduces the energy intensity for carbon capture by nearly 30% as compared to the MEA (Mono ethanol amine) reference process.

The DMX™ process is a CO2 post-combustion capture process based on absorption by a demixing solvent, the DMX™ solvent.

The DMX™ process has been developed for CO2 capture on coal power stations flue gases and steel gas. It can also be used for capturing CO2 from other type of emitters such as waste incinerator, cement plant, district heating as well as production of electricity from biomass. This process is well adapted for CO2 capture on industrial smoke or industrial gas when the CO2 partial pressures are low to medium.

The DMX™ solvent is a specifically designed solvent that is demixing under specific temperature and CO2 partial pressure’s conditions. When in contact with CO2, the formation of two phases can be observed, which effectively capture the CO2.

The demixing principle

demixing

Currently, one of the main challenge of the industry is to significantly increase the energy performances of CO2 capture solutions. They represent the costliest part of the CCS process. The DMX™ solvent tackles this issue. It has a high cyclic capacity (4 times higher as compared with the MEA reference) and only the CO2 rich phase needs to be regenerated. As it is very stable, it may be regenerated at higher temperature than amine solvents such as MEA, which allows producing the CO2 in pressure.

DMX™ solvent is also less corrosive and carbon steel may be used as principal material thus reducing also the CAPEX compared to other first-generation solvents.

Gasel®

Axens’ Gasel® Technology aims at producing ultra-clean liquid products, notably SAF, diesel and petrochemicals feedstock (naphtha, waxes), through the conversion of synthesis gas.

The synthesis gas (also called syngas) shall be obtained from several sources such as for instance biomass, wastes, etc.

This Fischer-Tropsch (FT) route is commonly accepted as one of the most promising mid-term solutions for the production of alternative fuels and petrochemicals, including Biomass-To-Liquids (BTL), Wastes-To-Liquids (WTL) and Power-To-Liquids (PTL) pathways.

Lower emissions of particles, sulfur oxides and other pollutants
Fully compatible with current engines and infrastructure, and thus certified as drop-in fuels
Large range of possible capacities ability to process syngas from many different origins / feedstocks, adjustable product slate to renewable/biofuels and chemical markets
Adsorbents

Sulfur Removal Adsorbents for Biogas

Hydrogen sulfide (H2S) and light mercaptans are common contaminants that must be removed from various gases such as biogas and landfill-derived methane in particular. Such sulfur species are extremely corrosive and must be removed to meet fuel gas specifications, pipeline specifications and air quality regulations.
