2019 Session 4: Biorefinery Technology
"Organosolv Fractionation and Flexible Biorefinery"
Presenter: Ali Manesh, American Science and Technology
Scientists have long been interested in a flexible biorefinery that can produce different bio-based products depending on market demand. Among many ideas, application of various types of organosolv processes have proven to be the most viable pathway toward this goal.
Attis Innovations has developed a new alternative pulping process that uses organic solvent for fractionation of lignocellulosic biomass to produce cellulose (for paper or sugar production), pure lignin, and various bio-chemicals. In the past ten years, Attis has built two pilot plant biorefineries, a 40 gallon capacity plant and a 2000 gallon capacity plant, allowing their new technology to migrate from a lab environment to the larger scale testing facilities and prove the scalability of their Organosolv process and its commercial viability.
In the past 5 years, the large scale pilot plant has been used by various pulp and paper companies, many biomass owners, and several technology developers to perform various research and development tests, test various ideas, and reduce risk of future investment.
During this presentation you will learn:
1. Lessons learned from both pilot plant studies
2. New opportunities to produce various bio-chemicals by changing some of the process parameters (such as time, temperature, pressure, pH, etc.)
