摘要： This invention discloses an integral hydrocarbon conversion apparatus and process 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.

摘要： The suspension density and mass flow rate of a particular solids and gas mixture transported to a reactor is controlled by using a radiation source and detector. The suspension density is measured and compared to a preselected value. The result is converted to a control signal which may be used to control venting from the vessel, and/or the amount of aeration gas supplied to the lower portion of the vessel, in order to maintain the suspension density at the preselected value and provide a constant mass flow rate.

摘要： Catalyst and hydrocarbon vapors are separated in a cyclone zone attached to the discharge of a riser cracking operation. Vortex stabilizing means separating the cyclone zone from a stripping zone allows stripping gas from said stripping zone to be passed upwardly into said cyclone zone countercurrent to the downward flow of catalyst, thereby improving the separation and stripping of gaseous hydrocarbons from separated catalyst. The combined cyclone-stripping zone reduces catalyst hydrocarbon contact time, thereby improving gasoline yield and olefin content, decreasing gas make, and reducing coke deposits.
