| titleOfInvention | Upflow three-phase fluidized bed coal liquefaction reactor system |
| abstract | A coal/liquid slurry is conducted upwardly in a three-phase fluidized state through a plurality of vessels connected in series, with the gas generated in each individual vessel being purged to a common header by a pressure control system included in each stage for ensuring control of flow through the reactors. The lead vessel includes the following features: a narrow, bottom entrance section designed to produce a superficial liquid velocity which is higher than the minimum fluidization velocity of the heaviest, largest particles in the slurry, so that all entering particles can be fluidized in the entrance section; an expanded upper section designed to slow the upflow of the slurry to a superficial liquid velocity sufficiently lower than the aforesaid minimum fluidization velocity to carry upwardly all particles which are essentially organic in composition but insufficient to carry upwardly a major portion of particles which are essentially nonorganic in nature, so that such major portion of essentially nonorganic particles settle from the upper section and do not carry over to a subsequent vessel; and a side opening at the intersection of these two sections for the continuous withdrawal of a slurry of those particles which settle from the upper section. The vessels subsequent to the leading vessel each have a uniform diameter smaller than the diameter in the lead vessel, so that particles passed from the lead vessel will not settle in the subsequent vessels. Each subsequent vessel also has vertical internals to provide a close approach to plug flow performance. Also, entry ports are provided at the base of each subsequent vessel for hydrogen gas addition. |
