A PROCESS FOR EFFECTING CATALYTIC CONVERSION OF HYDROCARBONS WHICH COMPRISES CONTINUOUSLY HEATING A CONTIGUOUS, REFRACTORY MASS OF HEATTRANSFER PEBBLES IN AN UPPER ENCLOSED ZONE TO A TEMPERATURE ABOVE CONVERSION TEMPERATURE; GRAVITATING THE HEATED PEBBLES THROUGH A SERIES OF PARALLEL, VERTICAL PASSAGEWAYS BETWEEN AND IN CONTACT WITH VERTICAL ROWS OF GAS-PERVIOUS CATALYST MASSES IN A CONVERSION ZONE, PASSING A VAPOROUS FEED STREAM COMPRISING PRINCIPALLY HYDROCARBON THROUGH SAID CONVERSION ZONE SO AS TO PASS THROUGH SAID CATALYST MASSES AND CATALYTICALLY CONVERT THE HYDROCARBON TO MORE DESIRABLE GASEOUS PRODUCTS; AND RECOVERING A GASEOUS PRODUCT FROM THE CONVERSION ZONE.
