Abstract
<PICT:0608859/III/1> In a process in which contact particles contaminated with carbon are regenerated by treatment as a fluidized mass with oxygen-containing gas, cool contact particles are continuously or intermittently injected into the effluent regenerating gas, immediately after its separation from the regenerated particles, and over a substantial part of the disengaging space. As shown, a reactant, e.g. gas oil, heavy or light gas oil naphtha, &c., from line 10, regenerated catalyst from line 14 and steam from line 16 (which may also serve for vaporized oil) pass to a reaction vessel 22 through a distributer head 18, the reaction products escaping through separator 32. The catalyst may be a cracking or reforming catalyst. The spent catalyst is stripped in zone 40 by gas introduced by lines 42, and fluidized by the introduction of gas by lines 43, 44, passes by pipe 54 to regeneration vessel 58 admixed with air or other regenerating gas from line 52. After regeneration in a fluidized condition, the catalyst returns via line 74 to line 14. Fluidizing gas lines 82 are shown. A proportion is, however, withdrawn through pipe 118, and after cooling in an indirect heat exchanger 122, passes through pipe 134 to a header 136 whence it is uniformly distributed at below, say, 500 DEG F. in the dilute phase 68 of the catalyst in regeneration vessel 58, to reduce the temperature to 1000-1050 DEG F. Emergency cooling water sprays 142 are also provided. Regeneration gases escape through separator 84 to line 88, to which a proportion of cooled catalyst may also be introduced, and pass through a heat exchanger 92 to an electrical precipitator 96. The separated catalyst fines are admixed with coarser particles from line 103, and fluidized by gas from lines 102, 106 are returned to the regeneration vessel 58 admixed with air from line 114. Specifications 590,244 and 593,185 are referred to.
