IN A HYDROCARBON CONVERSION SYSTEM IN WHICH SOLID CONTACT MATERIAL IS PASSED CYCLICALLY THROUGH SEPARATE ZONES WHEREIN SAID MATERIAL IS CONTACTED WITH DIFFERENT GASES UNDER DIFFERENT GASEOUS PRESSURES, THE METHOD OF TRANSFERRING SAID CONTACT MATERIAL BETWEEN SAID ZONES WHILE MAINTAINING A SUBSTANTIAL GAS SEAL THEREBETWEEN WHICH COMPRISES THE STEPS OF PASSING SAID CONTACT MATERIAL FROM THE ZONE OF LOWER GASEOUS PRESSURE DOWNWARDLY IN A CONFINED PATH AS A COMPACT MOVING COLUMN, ELEVATING SAID CONTACT MATERIAL FROM THE LOWER END OF SAID COLUMN THROUGH AN ELONGATED CONFINED PATH WHEREIN THE GASEOUS PRESSURE IS SUBSTANTIALLYI UNIFORM THROUGHOUT, PASSING ALL SAID ELEVATED CONTACT MATERIAL DOWNWARDLY IN A CONFINED PATH FROM THE UPPER END OF SAID ELONGATED CONFINED PATH AS A SECOND COMPACT MOVING COLUMN, INTRODUCING SAID CONTACT MATERIAL AT THE LOWER END OF SAID SECOND COLUMN INTO THE CONTACT ZONE OF HIGHER PRESSURE, AND INTRODUCING A GASEOUS SEALING MEDIUM AT A LOW POINT IN SAID SECOND COLUMN TO PROVIDE A PRESSURE THEREAT GREATER THAN THE PRESSURE IN SAID CONTACT ZONE OF HIGHER PRESSURE,
