Abstract
A process for regenerating an adsorbent material in the form of particles charged with at least two volatile cpds. of different thermal stabilities incorporates calcination of one of the volatile cpds. in a first contact column in which the material is entrained and put into suspension by a current of oxidising gas, being brought there to sufficiently high temp. Gaseous products desorbed in this first column are readsorbed by cooling in a second contact column. The process is partic. applicable in the regeneration of particles of alumina which have adsorbed tars and fluorinated cpds. The process is cheaper and the appts. more compact than rotary furnaces previously used. In addn. fluorinated cpds. are largely volatilised and a complementary purificn. of the air is used in these two cases, to make it non-polluting before its discharge to the atmosphere.
