Method for the cooling of solid residues of gasification
TLDR
In this article, the authors describe a method and apparatus for cooling the solid residue of gasification of a reactor operated at a pressure above atmospheric for the hydrogenation of carbonaceous materials, where the residual heat which corresponds to the difference between the desired final temperature and the temperature after cooling by the liquid, is eliminated by a gas blown into the bottom region of the cooling apparatus and/or by indirect heat exchange.Abstract:
The present specification describes and claims a method and apparatus for use in cooling the solid residue of gasification of a reactor operated at a pressure above atmospheric for the gasification of carbonaceous materials The residue of gasification is conducted out of the reactor into a cooling apparatus located therebelow and flows through the cooling apparatus from the top to the bottom thereof A cooling liquid is introduced into the solid residue in the upper region of the cooling apparatus and is metered such that the greater portion of the heat contained in the residue is eliminated in the form of heat of vaporization, sensible heat and chemical binding energy with the resultant steam and reaction products produced The remaining residual heat which corresponds to the difference between the desired final temperature and the temperature after cooling by the liquid, is eliminated by a gas blown into the bottom region of the cooling apparatus and/or by indirect heat exchangeread more

Recovery of retorted shale from an oil shale retorting process
Roland F. Deering,John H. Duir +1 more
TL;DR: In this article, the retorted shale particles are recovered from a retort and delivered to a gas lift for transport to a fluidized combustor by passage, serially, through a sealing vessel, a crusher preferably operating at retort pressure, and a surge vessel.

Gasification of carbonaceous solids
Paul W Garbo,Kwauk Mooson +1 more
TL;DR: In this article, a process for the gasification of a solid carbonaceous feed material by an endothermic gasification reaction is described, in which the carbonaceous material in particle form is mixed with particles of solid inert heat carrier material at a temperature substantially in excess of the temperature required for gasification.
