Abstract: The present invention generally relates to a catalytic gasification of coal. Catalytic gasification of a Wyodak low-sulfur sub-bituminous coal from the Powder River Basin of Wyoming was investigated using an inexpensive sodium carbonate catalyst applied via incipient wetness impregnation. Experiments in an atmospheric pressure fixed-bed laboratory gasifier were performed to evaluate the effects of reaction temperature, feed gas steam content, and Na2CO3 loading on the catalytic gasification of the Wyodak coal. The temperature range investigated (700-900° C.) was selected with consideration of the Na2CO3 melting point (850° C.) to reduce the loss by volatilization of sodium. Sodium was found to be active during both pyrolysis and gasification steps. The catalyst was most cost-effective at addition levels of approximately 3 wt %. The random pore model provided a good fit to the conversion versus time data collected under both the catalytic and the uncatalytic conditions.
