Fluid Coke
Photo credits: Ralph Gray. Fluid coke is made in a continuous process in which heated feedstocks are sprayed into a fluidized bed of hot (500°C) coke particles. The feedstock is vaporized and deposited on the coke particles. The particles grow by layers until they are removed and new seed coke particles are added.
