A method for making a silica supported catalyst involves impregnating a silica component with a catalytic metal using an aqueous, alkaline bath before drying. More specifically, the method involves forming and washing a silica component, such as a silica gel or a co-gel, for example a silica-zirconia co- gel. Then, the washed silica component is contacted with the alkaline bath to effect the impregnation with the catalytic metal, such as cesium, to form an activated silica component. Subsequently, the activated silica component is dried to form the catalyst. The resulting catalysts demonstrate good mechanical strength.
L'invention concerne un procédé de production de catalyseur à support de silice qui consiste à imprégner un constituant de silice avec un métal catalytique au moyen d'un bain alcalin aqueux avant séchage. Plus particulièrement, ledit procédé consiste à former et à laver un constituant de silice, de type gel ou co-gel de silice, par exemple un co-gel de silice-zircone. Ensuite, le constituant de silice lavé est mis en contact avec le bain alcalin afin que soit effectuée l'imprégnation avec le métal catalytique, de type césium, afin de former un constituant de silice activé. Le constituant de silice activé est ensuite séché afin de former le catalyseur. Les catalyseurs obtenus présentent une bonne résistance mécanique.
