In situ retorting with water vaporized in situ

Patent ·
OSTI ID:6684838

A combustion zone is advanced through an in situ oil shale retort containing a fragmented permeable mass of oil shale particles by introducing into the retort on the trailing side of the combustion zone: water, at least sufficient fuel to vaporize the water, and sufficient oxygen to oxidize the fuel for vaporizing the water and to form a gaseous combustion zone feed containing water vapor and oxygen. The gaseous combustion zone feed is for introduction into the combustion zone to advance the combustion zone through the fragmented mass of particles and produce combustion gas in the combustion zone.
