Laboratory studies carried out by Alcan showed that fluid coke, being of consistent uniform spherical size, could easily be fluidized, with the fluidized bed being able to carry an electrical current. This discovery led Alcan people to the conclusion that electric calcination in a fluidized bed would be a most favorable method for calcining fluid coke. It is the purpose of this paper to outline the main features of a one‐ton per hour pilot unit which was built to study this new calcination technique, and in particular to focus attention on the numerous problems that had to be solved before obtaining a successful operating unit.
