Abstract
- Catalytic gasification of a Wyodak low-sulfur sub-bituminous coal from the Powder River Basin of Wyoming was investigated using an inexpensive catalyst, Na 2 CO 3 , widely available in Wyoming. Experiments were performed in an atmospheric pressure fixed-bed laboratory gasifier. The effects of different factors including feed gas composition, catalyst loading and reaction temperature on the associated coal pyrolysis and char gasification were evaluated. Na 2 CO 3 was found to be active during both pyrolysis and gasification steps and it can considerably decrease the activation energy of gasification step. The optimal Na 2 CO 3 addition level is approximately 3 wt.%. Shrinking core model and random pore model can be used to fit the kinetic data obtained under both non-catalytic and catalytic conditions.
