ABSTRACT:
A method for generating heat from retorted oil shale particles which are carrying a deposit of carbon wherein the particles are lifted upwardly in a heating chamber using a carrier gas and the carrier gas is controlled in relation to the particles so that at any given time during the lifting step a substantial amount of the particles fall downwardly for a finite distance thereby causing internal backmixing of the heated falling particles with relatively cooler rising particles.
