    • Process and apparatus for the removal of carbonaceous materials from particles containing such materials, comprising introducing said particles into the lower part of a first, riser-type reactor, into which lower part an oxygen-containing gas is introduced, the reactor being operated under entrainment conditions with a relatively high density phase in the lower part and with a relatively low density phase in the upper part at a temperature suitable to burn off carbonaceous materials at such a rate that the flue gas at the top of the reactor does not contain any substantial amount of oxygen, separating solids and gas at the top of the reactor, introducing the separated particles into the upper part of a second, fluidized bed-type reactor while introducing an oxygen-containing gas into the lower part of the second reactor, the reactor being operated under fluidized bed conditions at a temperature suitable to burn off carbonaceous materials, the amount of oxygen-containing gas being established in such a way that the flue gas at the top of the reactor is substantially free of oxygen, removing processed particles from the lower part of the reactor, and recirculating a part of the processed particles to the lower part of the riser-type reactor.
    • 从含有这种材料的颗粒中除去含碳物质的方法和装置,包括将所述颗粒引入第一升管式反应器的下部,下部引入含氧气体,反应器在夹带下操作 在下部具有相对高密度相的条件,并且在上部具有相对低密度相的条件,其温度适于燃烧碳质材料,使得反应器顶部的烟气不含任何实质的 反应器顶部的氧气分离固体和气体,将分离的颗粒引入第二流化床型反应器的上部,同时将含氧气体引入第二反应器的下部,反应器 在适于燃烧含碳材料的温度下在流化床条件下操作,含氧气体的量被确定 以这样的方式使得反应器顶部的烟气基本上不含氧,从反应器的下部除去加工的颗粒,并将一部分处理过的颗粒再循环到提升管式反应器的下部 。
