is passed up through the particles at a rate strong enough for them to
lift and not fall back into the fluidized phase above its free surface
by carryover in the fluid stream. The bed of particles in this state
shows the appearance of boiling. In heterogeneous catalytic reactions,
the catalyst loses its activity with operating time.
