A high pressure, optically accessible fast pyrolysis reactor aimed at eliminating char formation during biomass gasification was constructed and tested at atmospheric pressure with cellulose particles. A high pressure, optically accessible coal steam gasification system was assembled following stand alone system tests for the steam generator, coal feeder and electric heater subassemblies. A plug flow reactor model was developed to better understand the heat and mass transfer and chemical kinetic processes in the gasification reactions. A new counter flow burner suitable for simultaneous velocity and species concentration measurements of flames burning fuel vapor and air at various scalar dissipation rates is ready for experiments, and preliminary computations for this burner flame were completed. In summary, the work proposed on most tasks for the first year of the project is complete with the exception of catalyst selection for the hydropyrolysis H2BiOil and Hydro De-Oxygenation HDO processes. These two catalyst selection tasks are underway as a part of a follow-up year two project of the current program.
