BIOMASS TO FORMIC ACID (OXFA
PROCESS)

W
e present a detailed kinetic study of the selective catalytic oxidation
of different biogenic substrates to formic acid (OxFA process) using
two different homogeneous polyoxometalate catalysts. By using high
oxygen pressures (30–60 bar) and temperatures of 80–90°C in aqueous
solution, we were able to investigate the rate-determining substrate
oxidation step catalyzed by the oxidized form of the polyoxometalates
(POMs) by keeping the concentration of the catalytic active species
constant. Under these conditions, kinetic parameters like effective
reaction order and reaction rate constants could be determined by the
differential method for model substrates like glucose, fructose, sorbitol
and gluconic acid. Finally, a detailed kinetic study for water-insoluble
biomasses like beech and spruce wood showed differences in formic acid
(FA) formation and product selectivities depending on the composition of
the wood in terms of their ratios of lignin, cellulose and hemicellulose.
Jakob Albert is currently working as Assistant
Professor and Head of the research group “Bio-
mass and Sustainable Production of Platform
Chemicals” at FAU’s Institute of Chemical Reac-
tion Engineering (CRT). He holds a Diploma in
2011 and a PhD degree in 2014 from the FAU in
Chemical Engineering. His key activities are in
the research fields of biomass valorization, sus-
tainable platform chemicals, polyoxometalate
catalysts and multiphase reaction systems. He
is an inventor on 19 invention disclosures and
patents and has received numerous scientific
awards e.g. the Promotionspreis of the Tech-
nical Faculty of the FAU in 2014, a Max-Buch-
ner-Scholarship in 2015, an EAM Starting Grant
2015, an Innovation MINT-Award 2016 and the
Science Sets Sail Award of the Excellence Clus-
ter Engineering of Advanced Materials in 2017.
