ABSTRACT:
The invention relates to a hydrocarbon-containing solids retorting process, such as, for example, shale, coal, tar sands, etc., the particles of which are below 6 mm in size, at a vertical entrainment regime, with superheated steam.
As an alternative to the process, the preheating of the solid charge to be fed to the reactor is foreseen, by a stream of retorted solids, removed from the primary separator, when effecting separation of the solid and gaseous phases from the retorting products. Heat exchange to the reactor is augmented by the use of static mixing devices provided in said reactor.
