TLDR
In this article, a process for retorting a carbon containing solid, especially oil shale, comprises passing heat transfer particles and raw particles of carbon containing liquid downwardly through a fluidized retort zone containing a plurality of baffles to prevent gross vertical backmixing.Abstract:
A process for retorting a carbon containing solid, especially oil shale, comprises passing heat transfer particles and raw particles of carbon containing solid downwardly through a fluidized retort zone containing a plurality of baffles to prevent gross vertical backmixing. The heated solid particles and heat transfer particles are then passed to a moving packed bed retort to pyrolyze the carbon containing solid particles.read more

Patent
Direct use of methane in coal liquefaction
TL;DR: In this paper, a process for converting solid carbonaceous material, such as coal, to liquid and gaseous hydrocarbons utilizing methane, was described, with a residence time of about 20-120 minutes at a temperature of 250°-750° C.
Patent
Stripping process with horizontal baffles
TL;DR: In this paper, a baffle-style stripping arrangement for an FCC process having substantially horizontal stripping baffles is described, which includes a perforated section and a downcomer section which generates transverse movement of catalyst across the baffle to ensure adequate vertical movement of stripping media.
Patent
Retorting with sintered or fused solids
TL;DR: An improved process for retorting a solid carbonaceous material at elevated temperatures was proposed in this paper, where a portion of the spent solids withdrawn from the retort was heated to a temperature within the range from about 1600° F to about 2400° F.
Patent
Process for coking contaminated pyrolysis oil on heat transfer material
TL;DR: In this paper, the heavy oil fraction of pyrolysis oil vapors containing concentrated contaminants is coked on hot heat transfer material and mixed with raw feed in a retorting vessel provided with an inert stripping gas.
Patent
Steam recycle used as stripping gas in oil shale retorting
TL;DR: In this article, the steam content and pressure of a recycled steam/hydrocarbon gas mixture in an oil shale retorting process is raised by high quality makeup steam producing a retort stripping gas of high efficiency (high oil yield) with minimal water consumption.

Staged turbulent bed retorting process
Gordon E. Langlois,Paul W. Tamm +1 more
TL;DR: In this paper, a continuous process for the retorting of shale and other similar hydrocarbon-containing solids of a broad particle size distribution is described, in which the solids to be retorted are introduced into an upper portion of an elongated vessel with a solid heat transfer material at an elevated temperature.
Patent
Shale retorting process
Gordon E Langlois,Tamm Paul W +1 more
TL;DR: Disclosed as discussed by the authors is a process for the retorting of shale and other similar hydrocarbon-containing solids in which the solids to be retorted are mixed with a solid heat transfer material to rapidly heat the hydrocarbons to a high temperature.
Patent
Method and apparatus for pyrolyzing oil shale
TL;DR: In this article, the fine raw shale particles not easily separable from the shale ash are removed prior to contact of the raw shale with the shale ash and combustion gases by direct contact thereof with raw shale particles.
Patent
Simplified liquefaction pyrolysis process and apparatus therefor
TL;DR: In this paper, a cyclone reactor-separator is used to separate the vaporized product of pyrolysis from the solids, and the carbon is partially combusted for recycling to the cyclone this paper.
