The present invention relates to a conversion of fuel grade coke produced through thermal cracking of heavy petroleum residue to anode grade coke. More specifically, the present invention provides a process which employs high sulfur fuel grade coke as the feedstock to produce low sulfur coke which can be used to manufacture electrodes for use in aluminium industry. Further, the invention also relates to a system for removal of metal content from coke and conversion of fuel grade coke to anode grade coke.

A method of treating a powder material includes classifying a powder material within a vessel by using a fluidized bed of the powder material to separate smaller particles of the powder material from larger particles of the powder material, and degassing the separated smaller particles and the larger particles within the vessel by heating and fluidizing the larger particles and the separated smaller particles.

A powder processing apparatus includes a vessel. The vessel has an interior chamber that includes top and bottom regions, and a gas outlet to the exterior of the vessel. A wall divides the bottom region into first and second sub-regions, with the top region extending above the wall. First and second porous plates divide the first and second sub-regions such that there are first and second manifold regions below the first and second porous plates. The first and second gas manifold regions include first and second gas inlets from the exterior of the vessel.

The present invention provides a dry method heavy medium separator adopting a dry method heavy medium separation bed and a separation device. According to the dry method heavy medium separator, a floating material end medium drum screen and a sediment end medium drum screen are arranged below a floating material discharge end and a sediment discharge end of the dry method heavy medium separator and used for separating products from media; a bag-type dust collector is used for collecting dust, a dust collector pipeline is arranged at the top of the dry method heavy medium separator, the air draft volume is larger than the air supply volume during working of the dry method heavy medium separator, the inside of the separator is in a negative pressure state, and therefore dust in the dry method heavy medium separator cannot escape; and the whole system is in a fully closed working state. According to the dry method heavy medium separator adopting the dry method heavy medium separation bed and the separation device, the problems that the fluidization density is instable, the air flow distribution is not uniform in a fluidization process, the medium separation efficiency of an existing medium separation screen for fine materials is low, the magnetic medium content of the fine materials subjected to medium separation is high, and the like are solved, and the medium separation efficiency for fine materials can be improved remarkably.
