A PROCESS FOR HOMOGENEOUS NON-CATALYTIC PARTIAL OXIDATION OF OXIDIZABLE VAPORS VAPOROUS AT REACTION TEMPERATURE WHICH COMPRISES PASSING A STREAM OF SAID HYDROCARBONS IN ALTERNATING SEQUENCE UPWARDLY THROUGH A PLURALITY OF DENSE PHASE REGIONS AND VOID REGIONS WITHIN A REACTION ZONE, SAID DENSE PHASE REGIONS CONTAINING TURBULENT FINELY DIVIDED FLUIDIZED NON-CATALYTIC SOLIDS HAVING AN APPARENT DENSITY OF ABOUT 20 TO 40 LBS./CU FT. AND SAID VOID REGIONS CONTAINING AN ESSENTIALLY HOMOGENEOUS VAPOR PHASE HAVING AN APPARENT DENSITY OF NOT MORE THAN 1 LB,/CU. FT., CONTACTING THE SAID HYDROCARBON STREAM IN SAID DILUTE REGIONS AT A REACTION TEMPERATURE BETWEEN ABOUT
