the movement of solid particles in hydrocyclone

US3817856A Method for contacting liquid and solid

an apparatus and a process wherein a solid liquid slurry is ciruclated in a vertical reactor by means of gas lift action in a centrally located tube inside the reactor. one or more hydrocyclones are used to clarify luqiid product leaving the reactor and to return slurry solids to the reactor. the process is particularly desirable for catalytically desulfurizing residual oils in the presence of
