Abstract
Apparatus for contacting particles with a fluid includes two tubes having different diameters and each including a straight lower section inclined relative to the horizontal and a straight, vertical upper section, the lower ends of the tubes being joined together. Fluid introduced into the lower ends of the tubes allows particles to drop slowly in the larger diameter tube and fluidizes the same particles in the smaller diameter tube.
