Process

The catalytic oxidation “OxFA-process” enables the conversion of biomass by partial oxidation. The biomass used in each case is selectively degraded with a water-soluble catalyst to the C1 building blocks formic acid and carbon dioxide.. The technical process can be subdivided in three parts, the pretreatment of biomass, the oxidation process and the isolation of main product: bio formic acid.

Substrates

Competitive Advantage

catalytic – highly efficient
no fermentation, noble metal free catalyst, no additives, mild reaction conditions, low energy consumption

selective – low amount of residues
FA and CO2 as main products, no wide product distribution, little isolation and downstream requirements

practical – low pressure and temperature
low equipment costs, low operating costs, smaller installation, safer handling

biomass agnostic – wet and lignified
water soluble and non-soluble biomass, wet and lignified biomass, huge potential of technically usable biomass

decentralized – short transportation distances
ubiquitous biomass and biogenic residues, smaller plants for decentralized production, modular and standardized production

bio-based – exclusive upside potential
formic acid as bio-based platform chemical, a variety of additional products from syngas, deicing agents to synthetic fuels and additives

Substrates

From simple sugars to complex biomass many biogenic feedstocks are suitable

A special feature of the OxFA process is that the biomass used can be both hydrous and lignified. Due to the low demands of the process on biogenic feedstock, a broad range of biomass can be implemented in the process. Whether algae, bagasse, wood, corn silage, wheat straw or sugar beets: Many renewable raw materials can be converted into bio-based formic acid. Even residues from the food industry such as molasses, vinasses, pressed pulp, spent grain and pomace are also an excellent starting material for biogenic formic acid. Formic acid can be obtained sustainably even from waste such as fermentation residues or biological sewage or sewage sludge. Sugar and starch containing biomass exhibits extraordinary high yields in formic acid.

Depending on the substrate, up to one kilogram bio-based formic acid per kilogram dry matter can be produced.

IP and Patents

OxFA technology is patented on different levels of the process. We have several patents directly applied by OxFA, others were purchased and there is technical know-how not being disclosed. Our portfolio contains the catalyst itself, reactor design and process design as well as the downstream process to formic acid and it´s derivatives.

Research and Development

The OxFA process is based on intensive fundamental research in the field of catalytic oxygenation of biomass within the Chair of Chemical Reaction Engineering of the Friedrich-Alexander university (FAU) Erlangen-Nuremberg.

The OxFA GmbH commercializes the proprietary technology and optimizes the necessary catalysts and reaction technology. In further research projects together with the FAU and the Ostbayerischen Technischen Hochschule Amberg-Weiden new fields of application and downstream processes regarding also the field of bio-based are investigated.
