A fluid-solids contactor comprising an annular rotating fluidized bed and a method of using the same are disclosed. The fluid-solids contactor includes a vessel and a plurality feed inlets disposed thereon. The vessel comprises a stationary inner wall, an outer wall, and a chamber formed between the stationary inner wall and the outer wall. The feed inlets are configured to create an annular rotating bed with mixture of solids and a fluid when the solid particles and a fluid are fed into the chamber. The stationary inner wall of the vessel is permeable to the fluid such that the fluid from the chamber can be continuously withdrawn from the solids to the space within the stationary inner wall of the vessel.

The present invention is concerned with a process for providing a homogeneous particle-containing slurry comprising the steps of: (a) providing a vessel comprising at least one impeller rotating around a vertical axis of the vessel, wherein a rotational speed n.sub.1 of the at least one impeller is higher than n.sub.min according to equation (1), the vessel further comprising an inlet and an outlet; (b) introducing a particle-containing slurry into the vessel or introducing components forming the particle-containing slurry into the vessel; (c) rotating the at least one impeller at least around the vertical axis for homogenizing and/or maintaining a homogeneous particle distribution within the slurry; (d) withdrawing the homogeneous particle-containing slurry via the outlet; (e) reducing the rotational speed n.sub.1 of the at least one impeller to a reduced rotational speed n.sub.red, whereas n.sub.red is lower than n.sub.1 and higher or equal gas inlet than n.sub.min according to equation (1):
