Изобретение относится к глинозему, стабилизированному лантаном, сохраняющему большую удельную поверхность при высокой температуре, в частности после кальцинирования при 1200oС в течение 4-х часов. Изобретение относится также к способу получения этого стабилизированного глинозема из порошка глинозема, полученного быстрой дегидратацией гидроксида или оксигидроксида алюминия, согласно которому указанный порошок повторно гидратируется в присутствии соединения лантана и затем подвергается термической обработке. Стабилизированный глинозем можно использовать в качестве носителя катализатора.The invention relates to alumina stabilized with lanthanum, which retains a large specific surface at high temperature, in particular after calcination at 1200 o C for 4 hours. The invention also relates to a method for producing this stabilized alumina from alumina powder obtained by the rapid dehydration of aluminum hydroxide or oxyhydroxide, according to which said powder is rehydrated in the presence of lanthanum compound and then subjected to heat treatment. Stabilized alumina can be used as a catalyst carrier.
