Renewable Lignin Biofuel from an Industrial By-Product Stream
In collaboration with Liquid Lignin Company, an easily processable, flowable lignin has been discovered that can be used to continuously produce a clean-burning, low-ash biofuel from a key paper mill by-product stream.
Purification and Fractionation for making Ultrapure Lignin
Separation processes are being investigated that can convert the lignin recovered from a
dirty by-product stream into an ultrapure product containing less than 100 ppm metals. Such
a clean lignin has potential applications as a renewable biopolymer.
Watch video to see how we can simultaneously purify and fractionate lignin to make it ultrapure!
Carbonaceous Oligomers via Supercritical Extraction for Advanced-Materials Applications
The fractionation of carbonaceous oligomers via supercritical extraction has been used
to isolate the lowest mol wt liquid-crystalline PAH oligomer ever observed. Advanced-materials
applications are anticipated.
Rapid expansion of sub- and supercritical solutions into liquid solvents (RESOLV) process for encapsulation of bioactive agents in polymeric nanoparticles
Rapid expansion of sub- and supercritical solutions into liquid solvents (RESOLV) process has been used to fabricate
bioactive compound-loaded polymeric nanoparticles with tunable particle size, loading capacity, and release profile.
Renewable biopolymers such as poly(L-lactide) and lignins are being investigated as encapsulating matrices for natural
oxidative labile bioactive agents (e.g., catechins and curcuminoids).
