Abstract
High surface area aluminum phosphate-alumina compositions are prepared by reaction of a mixture comprising an aluminum alkoxide and an organic phosphate such as trialkyl or triaryl phosphate, in the presence of moist air to form a precipitate, separating the precipitate from the mixture, drying and calcining the precipitate and recovering a high surface area aluminum phosphate-alumina product which can be used as catalyst support or catalyst component, especially for hydrocarbon treating and conversion processes.
Claims26
An aluminum phosphate-alumina composition prepared by the steps which comprise reacting a mixture comprising an aluminum alkoxide and an organic phosphate having the formula (RO).sub.3 PO wherein R is a hydrocarbon radical selected from the group consisting of alkyl, aryl, cycloalkyl, alkaryl, aralkyl radicals and mixtures thereof, in the presence of moist air, to form an aluminum phosphate-alumina precipitate, and separating said aluminum phosphate-alumina precipitate from said mixture.
A catalyst comprising a metal component selected from the group consisting of Group IB, Group IIA, Group IIB, Group IVA, Group IVB, Group VIIB, Group VIII and mixtures thereof from the Periodic Table of Elements composited with an aluminum phosphate-alumina composition prepared by the steps which comprise reacting a mixture comprising an aluminum alkoxide and an organic phosphate having the formula (RO).sub.3 PO wherein R is a hydrocarbon radical selected from the group consisting of alkyl, aryl, cycloalkyl, aralkyl, alkaryl radicals and mixtures thereof, in the presence of moist air to form an aluminum phosphate-alumina precipitate.
