Abstract: Catalyst supports in bead form having a porosity of more than 60 percent formed by suspending finely divided silicate and/or silica fillers, carbonates, metal oxides and hydroxides compatible with a silica sol, in a silica sol so that the total weight of the solids is at least 50 percent by weight based on the silica content of the silica sol, dispersing the resulting mixture into drops of the required size, gelling the drops in a water-immiscible medium, separating the resulting granulate from the medium, subjecting the granulate to a heat treatment at 100* to 800* C, and subsequent acid treatment to remove a major portion of the cations, and washing the acid treated granulates.

Abstract: Process for the complete separation of an adsorbable gas component A from another substantially non-adsorbable gas component B in at least two adsorption zones 1 and 2 arranged one behind the other, comprising the following steps: A. IN THE FIRST STEP THE ADSORPTION ZONE 1 IS LOADED UNTIL COMPLETELY SATURATED WITH THE COMPONENT A; b. in the second step the feed gas in the interstitial volume of adsorption zone 1 is displaced with pure component A from a storage means and the sweeping gas, optionally together with the feed gas is delivered to the partially unloaded zone 2; C. IN THE THIRD STEP THE PURE COMPONENT A is liberated by heating of zone 1 and is delivered to a storage means. Thereafter the aforesaid steps are repeated however with interchanged functions of zones 1 and 2.

Abstract: POROUS, ABRASION-RESISTANT BEAD-LIKE CATALYST SUPPORTS FOR REACTIONS IN FLUIDISED BEDS CONTAINING IN A MATRIX OF A SILICON DIOXIDE GELMIXED WITH 0.1 TO 3% BY WEIGHT OF MAGNESIUM OXIDE A SILICON DIOXIDE FILLER WITH A SPECIFIC SURFACE AREA OF 20 TO 200 M.2/G. ACCORDING TO BET IN QUANTITIES OF FROM 20 TO 60% BY WEIGHT AND AN ARGILLACEOUS MINERAL FROM THE GROUP COMPRISING KAOLINITE, MONTMORILLONITE AND ATTAPULGITE IN QUANTITIES OF FROM 5 TO 30% BY WEIGHT, BOTH QUANTITIES BEING RELATED TO THE DRY GRANULATED MATERIAL. THE CATALYST SUPPORTS ARE OBTAINED BY SUSPENDING THE SILICON DIOXIDE FILLER AND THE ARGILLACEOUS MINERAL IN THE AFORESAID QUANTITIES IN AN AQUEOS, STABLE SILICON DIOXIDE SOL WITH A SPECIFIC SURFACE AREA OF 150 TO 400 M.2/G. ACCORDING TO BET AND GELLING THE LIQUID SUSPENSION BY THE ADDITION OF HYDRATED FINALLY DIVIDED MAGNESIUM OXIDE IN QUANTITIES OF 0.1 TO 3% BY WEIGHT AND FEEDING THIS GELLABLE MIXTURE IN DROPLET FORM INTO A LIQUID WHICH IS IMMISCIBLE WITH WATER AND FINALLY SEPARATING THE SULPHATED GRANULATED MATERIAL FROM THE LIQUID AND DRIVING AND HARDENING THE BEAD-LIKE GRANULATED MATERIAL FOR AT LEAST 10 MINUTES AT A TEMPERATURE OF FROM 500 TO 1000*C.
