    • A combination of a retorting process with a granular filtration zone whereby finely divided solids are removed from hydrocarbonaceous vapors. Raw hydrocarbon-containing particles such as shale are retorted by contacting them with heat carrier particles, and the resulting hydrocarbonaceous vapors withdrawn from the retort are contaminated with entrained, finely divided solids. These solids are removed from the hydrocarbonaceous vapors by passing the contaminated vapors at substantially the retorting temperature transversely through a downwardly moving bed of solid contact material maintained at approximately retorting temperature. The solid contact material is selected from retorted solids, heat carrier particles and mixtures of them. The mixture of finely divided solids and contact material withdrawn from the granular filtration may be returned to the process.
    • 蒸煮过程与颗粒过滤区的组合,其中从烃蒸气中除去细分的固体。 含烃原料如页岩是通过将其与热载体颗粒接触来进行蒸馏,并且从蒸馏器中排出的所得烃类蒸汽被夹带的细碎固体污染。 通过使受污染的蒸汽基本上通过蒸馏温度横向通过保持在大约蒸煮温度的向下移动的固体接触材料床,从烃类蒸气中除去这些固体。 固体接触材料选自蒸馏固体,热载体颗粒和它们的混合物。 从颗粒过滤中取出的细碎固体和接触材料的混合物可以返回到该方法中。
