Summary:
ISU researchers have developed a cost effective alternative route to depolymerizing lignin apart from pyrolysis.

Development Stage:
Description:
Lignin is the second most abundant natural polymer in the world (behind cellulose), and consists of a variety of different phenol-based monomer units. Despite the potential usefulness of the phenolic compounds as a chemical feedstock or for transportation fuels, lignin is rarely utilized for anything more than as a combustion fuel for process heat. The technology creates an alternative route to depolymerizing lignin apart from pyrolysis. It is a process in which lignin is treated with low cost, readily abundant chemicals, followed by low-temperature, low-pressure hydrogenation to stabilize the monomer units. This treatment lowers costs both in terms of capital investment (low pressure vessels, relatively benign chemicals) and operating costs compared to other methods.

Advantage:
• Inexpensive reagents
• Low operating expenses
• Minimal capital input
• Greatly reduced reaction temperature and pressure
Application:
Bio-based oils
