Реферат: PROCESO PARA LA FABRICACION DE UN SOPORTE QUE CONTIENE SILICE Y AL MENOS UN CONSTITUYENTE ELEGIDO ENTRE LA ALUMINA Y EL FOSFATO DE ALUMINIO, SEGUN EL CUAL SE MEZCLA UN ALCOHOL, AGUA, UN ALCOHOLATO DE SILICIO Y UN ACIDO EN CONDICIONES TALES QUE SE EVITA UNA GELIFICACION O PRECIPITACION DE SILICE, SE AÑADE UNA SOLUCION ACIDA DE UN COMPUESTO DE ALUMINIO Y/O UNA SOLUCION DE UNA FUENTE DE IONES DE FOSFATO, SE AÑADE UN AGENTE GELIFICANTE, SE RECOGE UN GEL QUE SE SOMETE A UN LAVADO AL AGUA Y A CONTINUACION MEDIANTE UN LIQUIDO ORGANICO, Y DESPUES SE SECA EL GEL POR ATOMIZACION HASTA LA OBTENCION DE UN POLVO, Y SE CALCINA EL POLVO. POLIMERIZACION DE OLEFINAS EN PRESENCIA DE UN CATALIZADOR QUE CONTIENE CROMO SOBRE UN SOPORTE TAL COMO SE DESCRIBE ANTERIORMENTE. PROCESS FOR THE MANUFACTURE OF A SUPPORT CONTAINING SILICON AND AT LEAST ONE CONSTITUENT CHOSEN BETWEEN ALUMINA AND ALUMINUM PHOSPHATE, ACCORDING TO WHICH ALCOHOL, WATER, A SILICON ALCOHOLATE AND AN ACID IN SUCH GEL CONDITIONS ARE MIXED OR PRECIPITATION OF SILICE, AN ACID SOLUTION OF AN ALUMINUM COMPOUND IS ADDED AND / OR A SOLUTION OF A SOURCE OF PHOSPHATE IONS, A GELING AGENT IS ADDED, A GEL IS COLLECTED THAT IS SUBMITTED TO A WATER WASH AND IS CONTINUED BY A ORGANIC LIQUID, AND THEN THE GEL IS DRIED BY ATOMIZATION UNTIL A POWDER IS OBTAINED, AND THE POWDER IS CALCINATED. OLEFIN POLYMERIZATION IN THE PRESENCE OF A CHROME CONTAINING CATALYST ON A SUPPORT AS DESCRIBED ABOVE.
