Abstract: A horizontal fluid bed retorting process is provided for preheating, retorting, combusting, and recovering heat from oil shale and other solid hydrocarbon-containing material. In the process, the combustor and heat recovery chambers share a common heat-conductive metal wall with and are positioned in side-by-side relationship to the cellular preheating and retorting chambers. The heat of combustion in the combustor and the heat recovered from the combusted shale or other material in the heat recovery chamber are transferred by conduction into the retorting and preheating chambers, respectively, to provide the process heat requirements for preheating and retorting the oil shale or other feed. The oil shale or other feed is fluidly moved in a generally horizontal S-shaped flow pattern through the preheating and retorting chambers in countercurrent flow to the combusted material in the combustor and heat recovery chambers.

Abstract: A process is provided for determining retorting conditions in an in situ oil shale retort. In the process, the thickness of the hot shale zone is determined by monitoring the off gases in response to changing the feed conditions, such as the temperature or flow rate, of the feed gas. The location and depth of the hot shale zone can be determined by monitoring the response time and temperature of the off gases when the proportion of steam and air in the feed gas is changed. The depth of the mineral decomposition zone can be monitored by monitoring the amount of carbon dioxide produced when the air content of the feed gas is substantially reduced. The depth of the kerogen decomposition zone can be determined by monitoring the amount of hydrogen saturated gases produced when the inflow of air in the feed gas is stopped.

The flame front is supported by a specially blended feed gas consisting essentially of air, steam and retort off gases. Product yield and quality are increased by varying the volumetric ratio of air, steam and retort off gases in the feed gas during retorting in proportion to the oil yield, or the relative richness, leanness and kerogen content of the oil shale being heated by the flame front, or in proportion to the amount of carbon residue on the retorted shale being combusted.
