Pyrolysis process for producing condensed stabilized hydrocarbons utilizing a beneficially reactive gas
This patent describes a process for producing condensed stabilized hydrocarbons from a solid particulate carbonaceous material. It comprises pyrolyzing a solid particulate carbonaceous feed material at a pyrolysis temperature by introducing the solid particulate carbonaceous feed material, a carbon containing particulate solid source of heat which has been heated to a temperature higher than the pyrolysis temperature and a beneficially reactive gas into a pyrolysis zone, under turbulent flow conditions and under conditions of time and elevated temperature sufficient to produce therefrom a pyrolysis product; separating the particulate solids from a gaseous mixture which comprises the pyrolytic product vapors; contacting the substantially solids-free gaseous mixture stream with a quench fluid comprising a capping agent suitable for stabilizing the newly formed volatilized hydrocarbon free radicals, under predetermined conditions of temperature and flow rate of capping agent sufficient for substantially simultaneously stabilizing substantially all of the newly formed volatilized hydrocarbon free radicals by termination, and substantially simultaneously condensing at least a major portion of the larger hydrocarbons, and separating at least a portion of the condensed stabilized hydrocarbons thusly formed from the gaseous residue.
