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.
