A Texas lignite was gasified with steam and oxygen in a 15.2-cm-i.d. top-feeding fluidized bed reactor at a pressure of 810 kPa (103 psig), average bed temperatures between 1030 and 1200 K, and molar steam-to-carbon feed ratios from 1.0 to 2.5. In-bed gas and solids sampling results indicate that the water gas shift reaction is at or near thermodynamic equilibrium and that the particle size is independent of the reactor operating conditions. A perfectly mixed model for the bed, incorporating Johnson gasification kinetics and an empirical formula for pyrolysis product yields, provides an excellent correlation of steady-state reactor data.
