          Appeal No. 1998-0558                                                        
          Application No. 08/564,942                                                  


          claims recite ethylbenzene or paraxylene.  The process of                   
          claim 23 calls for activating the catalyst by first oxidizing               
          the metal component of the catalyst with a circulating stream               
          of nitrogen and 1 percent oxygen, purging the reactor with                  
          pure hydrogen, and circulating pure hydrogen through the                    
          reactor at the recited conditions of temperature and pressure.              
          Appealed claim 32, on the other hand, does not define any                   
          particular conditions for activating the                                    





          catalyst, but provides for separating the effluent from the                 
          reactor into a hydrogen-rich fraction, a hydrocarbon-rich                   
          fraction containing benzene and toluene, and a second fraction              
          enriched in C  alkyl aromatic content.                                      
                       8                                                              
               Appellant submits at page 7 of the principal brief that                
          the appealed claims "do not stand or fall together for the                  
          reasons set forth below."  However, although appellant                      
          presents separate arguments for claims 32-34, appellant has                 
          advanced no arguments that are reasonably specific to any of                
          claims 2-5, 8, 23-26, 30 and 31.  Accordingly claims 2-5, 8,                
                                          5
