Each ozonization loop (1) which includes a compressor (2), an ozonizer (3), and a heat exchanger (8) for cooling the oxygen-ozone mixture, is associated with three cylinders (4,5,6) filled with silica gel. Each cylinder operates in succession in a cocurrent adsorption, in countercurrent desorption by a substitution gas, and in scavenging by taking off a part of the flow circulating in the loop. The scavenging flow is recovered and combined with the substitution gas. The substitution gas may be in particular impure nitrogen supplied by an air distillation apparatus producing the necessary oxygen.

An apparatus for producing ozone, comprising a case (40) containing an annular bed (49) of adsorbent material, the annular bed (49) occupying less than all the interior of the case (40), thereby to leave a volume between the annular bed (49) and the case (40); means (73) dividing the annular bed (49
An apparatus for producing ozone, comprising a case (40) containing an annular bed (49) of adsorbent material, the annular bed (49) occupying less than all the interior of the case (40), thereby to leave a volume between the annular bed (49) and the case (40); means (73) dividing the annular bed (49) into a plurality of sectors (72); partition walls (53, 57, 63 to 66, 71; 57, 88, 91, 92, 95; 102, 103, 105) dividing said volume between the annular bed (49) and the case (40) into four spaces (59, 74, 75, 58) respectively communicating with a first oxygen-ozone mixture inlet orifice (67), a second oxygen outlet orifice (69), a third substitution gas inlet orifice (70) and a fourth outlet orifice (68) of a production gas consisting essentially of the substitution gas and ozone, these partition walls putting said first orifice (67) in communication with an upstream side, with respect to adsorption, of a first group (721) of said sectors (72), said second orifice (69) with a downstream side, with respect to adsorption, of a second group (721, 723, 724) of said sectors (72) constituted by said first group of sectors (721) and a third group of said sectors (723, 724) adjacent to said first group (721), said third orifice (70) with an upstream side, with respect to countercurrent desorption, of a fourth group of said sectors (722) constituted by the remaining said sectors, and said fourth orifice (68) with a downstream side, with respect to desorption, of said fourth and third groups of sectors (722, 723, 724); and means (51; 55) for effecting a relative rotation between the annular bed (49) and said partition walls in such direction that each said sectors (72) is in succession and cyclically part of said first, fourth and third groups.
