A fluid distribution apparatus is disposed in a fluidized bed reactor and includes a distributor pipe configured to carry a fluid and a centerpipe fluidly connected to the distributor pipe and enclosing a conical distributor for receiving the fluid from the distributor pipe. The conical distributor is defined by an exterior radius including the centerpipe, an upper end including an upper angled circular plate, and a lower end including a lower circular plate. The fluid distribution apparatus further includes a plurality of inlet nozzles fluidly connected to the conical distributor and disposed through the centerpipe for distributing the fluid from the conical distributor to a bed of the fluidized bed reactor.
