ABSTRACT:
The present invention is a process for feeding particulate material to a fluidized bed reactor operated at greater than atmospheric through a standpipe wherein the ratio of the absolute pressure where the standpipe enters the fluidized bed reactor to the absolute pressure where the particulate material enters the standpipe is at least about 1.5 and gas is injected into the standpipe at a velocity which is about 20-80 percent of the minimum fluidization velocity of the particulate material.
