Abstract: A CATALYST SUPPORT IN THE FORM OF A MULTI-TUBULAR REFRACTORY MODULE IS MADE BY FORMING A PLASTIC COMPOSITION CONTAINING THEMATWRIAL OF THE SUPPORT OR A COMPOUND THERMALLY DECOMPOSALE OR RETRACTABLE THERETO, A LIQUID

AND A VISCOSITY-CONTROLLING SUBSTANCE, FORCING THE SAID COMPOSITION SUCCESSIVELY THROUGH A ZONE COMPRISING A PLURALITY OF DISCRETE PRIMARY CHANNELS WITHIN A SOLID BLOCK AND TEN A UNIFYIG ZOYING ZONE COMPRISING SECONDARY CHANNELS WITHIN THE SAME BLOCK, THE SECONDARY CHANNELS BEING INTERLINKED IN THE CONFIGURATION OF CONTINUOUS CURVES TRANSVERSE TO THE DIRECTION OF FLOW OF THE PLASTIC COMPOSITION, DRYING THE MODULE THUS PRODUCED AND CALCINING IT TO CAUSE THE FORMATION OF CERAMIC BONDS.
