ABSTRACT:
In a process for recovery of values contained in solid carbonaceous material, a solid carbonaceous material is comminuted and then treated at an elevated temperature with a capping agent which is at treating conditions either a liquid or a gas. The treating conditions are such that the capping agent is sorbed by the solid particulate carbonaceous material. The solid particulate carbonaceous material containing the sorbed capping agent is then subjected to pyrolysis preferably in the presence of a solid particulate source of heat and a transport gas in a transport flash pyrolysis reactor, to form a pyrolysis product stream. The solid particulate carbonaceous feed material is pyrolyzed and newly formed volatilized hydrocarbon free radicals are substantially simultaneously terminated by the sorbed capping agent as such radicals are formed, to form a pyrolysis product stream. The pyrolysis product stream contains a gaseous mixture and particulate solids which are separated from the gaseous mixture to form a substantially particulate solids-free gaseous mixture stream which contains capping agent terminated volatilized hydrocarbon free radicals, hydrogen depleted capping agent, pyrolysis product vapors and a transport gas.
Hydrocarbons of four or more carbon atoms in the gaseous mixture stream are condensed. A liquid stream containing the stabilized liquid product is then treated or separated into various fractions. A liquid containing the hydrogen depleted capping agent is hydrogenated to form a regenerated capping agent, at least a portion of which is recycled to the pyrolysis zone. In another embodiment the capping agent is produced by the process, separated from the liquid product mixture, and recycled.
