摘要： CATALYST IS ADDED TO A BED OF CATALYST IN CONTROLLED AMOUNTS BY AN EASILY CONTROLLED SYSTEM USING, FOR EXAMPLE, MOTIVE AIR TO MOVE CONTROLLED AMOUNTS OF CATALYST THROUGH A CONDUIT AND THEN ONTO A BED OF CATALYST AT REGULATED INTERVALS. CATALYST FLOW IS STOPPED WHEN A CYCLE TIMER STOPS THE FLOW OF AIR TO THE CONDUIT BECAUSE THE CATALYST STAGNATES WHEN THE MASS OF CATALYST PARTICLES INTRODUCED TO THE CONDUIT (BY A STANDPIPE FROM FRESH CATALYST STORAGE) ASSUMES ITS ANGLE OF REPOSE.
