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.
Claims9
A process for the treatment of solid particles of a particle size between 0.1 .mu.m and 10 cm, comprising urging said particles upwardly in at least one substantially tubular, metal, vibrating, helical coil having at least two turns, said particles being subjected to a temperature profile over most of their path in said coil and said particles being contacted with at least one fluid over at least part of their path, said process being characterized by electrical heating of at least one turn of the coil by the Joule effect to a temperature between 20.degree. and 1000.degree. C.
