Abstract

L'INVENTION CONCERNE UN PROCEDE POUR PREPARER DES SUPPORTS POUR CATALYSEURS ZIRCONE-SILICE D'UN GRAND VOLUME DE PORES, LES SUPPORTS RESULTANTS ET UN PROCEDE DE POLYMERISATION D'OLEFINES SELON LEQUEL ON MET EN CONTACT UNE OLEFINE OU UN MELANGE D'OLEFINES AVEC UN CATALYSEUR PREPARE AVEC CES SUPPORTS. ON PREPARE LES SUPPORTS EN FAISANT REAGIR UN COMPOSE DU ZIRCONIUM DE FORMULE MZR(CO).NHO, DANS LAQUELLE M EST UN ION DE METAL ALCALIN OU D'AMMONIUM ET N VA DE 0 A 10, AVEC UN COMPOSE DU SILICIUM DU TYPE ASIO, OU A EST UN METAL ALCALIN, DANS UNE SOLUTION AQUEUSE A UN PH EGAL A AU MOINS 11, PUIS EN AJOUTANT UNE SOLUTION ACIDE JUSQU'A UN PH DE 5 A 9 ENVIRON DE MANIERE A PRODUIRE UN HYDROCOGEL. L'HYDROCOGEL EST ENSUITE VIEILLI ET DEPOUILLE DES SOUS-PRODUITS SOLUBLES PAR LAVAGE D'ABORD A L'EAU, PUIS AVEC UNE SOLUTION AQUEUSE DE NITRATE D'AMMONIUM ET DE NOUVEAU A L'EAU. L'EAU EST ELIMINEE PAR L'HYDROCOGEL LAVE PAR DISTILLATION AZEOTROPIQUE OU PAR LAVAGE AVEC UN SOLVANT MISCIBLE ET ENSUITE CALCINATION DU XEROCOGEL RESULTANT.
