ABSTRACT:
There is provided an apparatus comprising rotating inner and outer concentric tubes. The inner tube provides a vapor zone and the annular space between the tubes provides a combustion zone. Hot particulate solids, such as sand, are advanced along an endless path through the vapor zone, back through the combustion zone and back into the vapor zone. In the vapor zone, oil is sprayed on the hot solids. The mixture is mixed and cascaded to obtain heat transfer from the solids to the oil, thereby generating hydrocarbon vapors and coke deposition on the solids. The vapors are removed by suction from the vapor zone. The coked solids are transferred into the combustion zone and cascaded and lifted and dropped therein to mix with added oxygen. Coke is burned to heat the solids which are then returned to the vapor zone. The vapors generated in the combustion zone are removed by suction. Segregation of the atmospheres in the two zones is achieved by a combination of maintaining equal pressures in the zones and using the solids, being transferred from one zone to the other, to block gas flow.
