This lecture will d iscuss our progress in developing materials-based separation processes for biorefinery applications. The discussion will be centered on the kraft pr ocess\, which is a high-volume biorefining process that currently yields b iopolymer (cellulose)\, biobased chemical (such as tall oil)\, and bioener gy (steam and electricity) products. The main byproduct of the process – k raft black liquor – is dewatered by energy-intensive multi-effect evaporat ion\, followed by combustion of the concentrated black liquor to produce s team and electricity. However\, black liquor is a potential high-volume fe edstock (available at > 1 billion tons/yr in kraft processes) for chemical production because it contains lignin and hydroxy acid fractions.
\nWe will highlight the key role of advanced separation processes in increa
sing the energy efficiency of the kraft process as well as enabling valori
zation of stream components. The discussion is placed in the context of th
ree interconnected issues. First\, we will illustrate the importance of im
agining biorefineries as an interconnected network of conversion and separ
ation processes\, and the possibility for materials-based separations to e
nable new ways of dewatering black liquor as well as valorizing black liqu
or components such as hydroxy acids and lignin. Second\, we will illustrat
e the differing separation challenges encountered in stream fractionation
versus product purification\, both of which are critical for biorefineries
. Third\, we will explore the development and identification of versatile
and inexpensive separation materials that can handle complex multicomponen
t streams in harsh conditions of temperature\, pH\, and high dissolved sol
ids content.
