Abstract
A method for operating a fluidized-bed reactor includes introducing an alkali-containing material into a fluidized-bed reactor and introducing hydrous clay into the fluidized-bed reactor, the hydrous clay having a moisture content of at least about 5% by weight. The method further includes heating at least a portion of the alkali-containing material and hydrous clay, such that at least a portion of the hydrous clay is at least partially calcined and the at least partially calcined clay adsorbs at least a portion of alkali present in the fluidized-bed reactor. The method further includes removing at least a portion of the at least partially calcined clay and adsorbed alkali from the fluidized-bed reactor.
