Abstract
A system provides an oxygen-bearing gas and gaseous reactant stream to a fluidized bed reactor using a sparger to entrain the oxygen-bearing gas into the reactant gas stream. A feed line couples the sparger to the reactor's fluidized bed and introduces the reactant gas stream and entrained oxygen-bearing gas directly into contact with the fluidized bed. A controller controls and maintains both the amount of oxygen-bearing gas and the gaseous reactant above an upper flammability limit, preferably with a safety margin of at least 10%.
