Shale retorting process
Disclosed 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 hydrocarbon-containing solids to a high temperature. The shale and heat-transfer material are entrained in a high-velocity gaseous stream and conveyed upward in a vertical dilute phase lift pipe retorting vessel, whereby the hydrocarbon-containing solids are rapidly heated to an elevated temperature vaporizing a minor portion of the hydrocarbons in the solid. The hydrocarbon-containing solids then pass into a disengaging zone wherein the gas and solids are separated. The partially retorted solids then pass into a gravitating bed retort and flow downward countercurrent to the flow of a stripping gas. The process is characterized by a high liquid yield and a minimum gas yield along with minimal amounts of volatile components being left in the retorted solids.
