process for the production of an amorphous oxide / alumina / aluminium phosphate - too for use on 'upgrading' of rueckstandsoelen.

摘要

A method for preparing an amorphous magnesia-alumina-aluminum phosphate catalyst support comprises the steps of: (a) forming an aqueous solution containing magnesium and aluminum ions and phosphoric acid; (b) precipitating amorphous magnesia-alumina-aluminum phosphate from said solution in the presence of a source of organic cation having a size equal to or larger than 2 Angstrom; and (c) separating the precipitate. o
