| description: |
The purpose of this project is to systematically study the devolatilization of Estonian oil-shales during pyrolysis. The project is of both theoretical and practical importance. The ability to predict formation of volatile products as well as the physical-chemical properties of pyrolysis oil (tar) and how those properties vary with process conditions is important for industrial-based production; i.e. for optimal product yields and properties. Two parallel approaches will be utilized. The first is to approach is to apply existing coal pyrolysis models; primarily the Functional Group-Depolymerization Vaporization Crosslinking (FG-DVC) model, to predict the decomposition behavior of Estonian oil-shales under a variety of pyrolysis conditions (from low to high heating rates; from vacuum to high pressure). The second approach will be to carry out an extensive devolatilization study experimentally. |
