Appeal No. 96-0037 Application 08/237,224 The appellants' invention is directed to a process for separating fluidized cracking catalyst solids from hydrocarbon vapors. The subject matter before us on appeal is illustrated by reference to claim 15, which reads as follows: 15. A process for separating fluidized cracking catalyst solids from hydrocarbon vapors comprising: (a) feeding a mixture of fluidized cracking catalyst solids and hydrocarbon vapors from a riser reactor into a separator having at least one semi-circular separating area; (b) deflecting the mixture off of a deflecting means in the separator into said at least one semi-circular separating area; (c) separating said mixture by inertial separation in said at least one semi-circular separating area into a hydrocarbon vapor product stream and a fluidized cracking catalyst stream; (d) withdrawing said hydrocarbon vapor product stream from said at least one semi-circular separating area through a horizontally upwardly disposed opening on the side of a horizontally disposed gas outlet which extends through said at least one separating area and parallel to said deflector in said at least one semi-circular separating area; and (e) withdrawing the fluidized cracking catalyst from said at least one semi-circular separating area. THE REFERENCE The sole reference relied upon by the examiner to support the final rejection is: Barnes 4,666,674 May 19, 1987 2Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
