Abstract
For the treatment of solid catalyst or adsorbent particles, particles are urged upwardly in at least one vibrating helical coil having at least two pitches or turns, the particles being subjected to a temperature profile on most of their path within the coil and being contacted with at least one fluid over at least part of their path. At least one pitch or turn of the coil is heated by the Joule effect at a temperature between 20.degree. and 1000.degree. C.
