ABSTRACT:
This invention discloses an integral hydrocarbon conversion apparatus having a downflow hydrocarbon reactor, an upflow riser regenerator and a horizontal cyclone separator to permit the conversion of hydrocarbonaceous materials to hydrocarbonaceous products of lower molecular weight in a near zero pressure drop environment. A leg seal is provided surmounted to the downflow reactor to insure that the pressure is at least 0.5 psi higher than the upper portion of the downflow reactor (higher than the loop seal valve) vis-a-vis the pressure in the lower portion of the downflow reactor.
