Reentech process

A cyclone outside the moving-bed catalytic colnmn serves to sort only catalyst particles of a desired size among the catalyst particles dropped to the lower portion. A nickel-molybdenum catalyst regenerator with an air injector serves to regenerate the catalyst transferred from the cyclone and the regenerated catalyst is then returned to the moving-bed catalytic cracker [29], 

The annual capacity of the Reentech plants is 6000 tonne/yr of plastic input yielding some 4.2 million litres of fuel oil [27], 

The Reentech process incorporates the following key process steps  

The carbon residues of catalytic cracking are separated by a cyclone.
