In-situ retorting with flame front-stabilizing layer of lean oil shale particles

Patent ·
OSTI ID:6900968
; ;

An in-situ retort and process are provided for underground retorting of oil shale. The in situ retort is formed with at least one flame front-stabilizing layer of minute lean oil shale particles which serves as a redistribution region or grid. When the flame front is ignited and passed through the retort with a feed gas, the flame front-stabilizing layer will stabilize and enhance horizontal uniformity of the flame front to substantially minimize burning of the product shale oil.
