Laboratory gasification studies via partial oxidation of biomass pyrolysis vapors
Evans, R. J., & Dayton, D. (1997). Laboratory gasification studies via partial oxidation of biomass pyrolysis vapors. In R. P. Overend, & E. Chornet (Eds.), Making a Business from Biomass in Energy, Environment, Chemicals, Fibers, and Materials: proceedings of the 3rd Biomass Conference of the Americas, Montréal, Québec, Canada, August 24-29, 1997 (Vol. 1, pp. 673-682).

Biomass gasification was simulated at the bench scale in a quartz-tube flow reactor by the partial oxidation of biomass pyrolysis vapors in various atmospheres. Small samples of switchgrass were pyrolysed at two temperatures, 700{sup o}C and 1000{sup o}C and subsequent gas phase reactions were studied at 850{sup o}C. The O{sub 2} concentration in the reactor was varied between 1% and 10% and in certain experiments steam was added to the atmosphere. The lowest O{sub 2} concentration corresponded to enough O{sub 2}, in addition to the oxygen in the biomass, to provide 30% of the stoichiometric limit to oxidize a 50.0-mg switchgrass sample. The point at which the oxygen was introduced into the reactor was also varied. A molecular beam mass spectrometer system was used to monitor the products formed at the various experimental conditions
