摘要： 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 in a pretreatment zone with a first capping agent which is at treating conditions either a liquid or a gas. The treating conditions are such that the first capping agent is sorbed by the solid particulate carbonaceous material. The solid particulate carbonaceous material containing the sorbed first capping agent is then subjected to pyrolysis in the presence of a second capping agent, and 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 first capping agent, or the second 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 agents, 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 agents is hydrogenated to form regenerated capping agents, at least a portion of which is recycled to the pretreatment zone and at least another portion is recycled to the pyrolysis zone. In another embodiment the capping agents are produced by the process, separated from the liquid product mixture, and recycled.

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.

The pyrolysis product stream contains a gaseous mixture and particulate solids.

Preferably the solid particulate source of heat is formed by oxidizing part of the separated particulate solids.

摘要： In a process for recovery of values contained in solid carbonaceous material, the solid carbonaceous material is comminuted (10) and then subjected to pyrolysis, in the presence of a solid particulate source of heat in a pyrolysis zone, to form a pyrolysis product stream (24). The pyrolysis product stream contains a gaseous mixture and particulate solids. The solids are separated from the gaseous mixture to form a substantially solids-free gaseous stream (28) which comprises volatilized hydrocarbon free radicals newly formed by pyrolysis. The solid particulate source of heat is formed by oxidizing part of the separated particulate solids (32). Condensed stabilized hydrocarbons are obtained by quenching the gaseous mixture stream with a quench fluid (76) which contains a capping agent for stabilizing and terminating newly formed volatilized hydrocarbon free radicals. The capping agent is partially depleted of hydrogen by the stabilization and termination reaction. Hydrocarbons of four or more carbon atoms in the gaseous mixture stream are condensed. A liquid stream (64) 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 the regenerated capping agent is recycled to the quench zone (34) as the quench fluid. In another embodiment capping agent is produced by the process, separated from the liquid product mixture, and recycled.

摘要： This invention discloses a process and apparatus for pyrolyzing particulate coal by heating with a particulate solid heating media in a transport reactor. The invention tends to dampen fluctuations in the flow of heating media upstream of the pyrolysis zone, and by so doing forms a substantially continuous and substantially uniform annular column of heating media flowing downwardly along the inside diameter of the reactor. The invention is particularly useful for bituminous or agglomerative type coals.
