Abstract
A method for the supply of hot solid particles, preferably hot spent substrate particles, to a retorting vessel for the extraction of hydrocarbons from a hydrocarbon-containing substrate according to which hot solid particles are supplied to a slide situated at an angle to the horizontal plane, fluidization gas is supplied to the fluidization means of the slide, which fluidization gas is passed through the fluidization means causing fluidization of the hot solid particles on the slide and displacement of the hot fluidized particles alone the slide, at least one draw-off vessel is situated between the slide and retorting vessel which is filled with hot fluidized particles from the slide, and fluidization gas is passed through fluidization means of each filled draw-off vessel causing the hot solid particles therein to flow into a respective inlet of the retorting vessel.
