Abstract
Official abstract text for this publication.
A heterogeneous catalyst suitable for use in alkane dehydrogenation has an active layer that includes alumina and gallia. The active layer is dispersed on a support such as alumina or silica-modified alumina.
First claim
Opening claim text (preview).
What is claimed is: 1 . A heterogeneous alkane dehydrogenation catalyst consisting of a combination of a) both aluminum oxide and gallium oxide dispersed as an active layer on b) an alumina support or a silica-modified alumina support. 2 . The catalyst of claim 1 , wherein the aluminum and the gallium in the active layer are present in a molar ratio of gallium to aluminum that is within a range of from greater than 0.5:1 to less than 15:1. 3 . The catalyst of claim 2 , wherein the molar ratio is within a range of from 1:1 to 10:1. 4 . The catalyst of claim 1 , wherein the aluminum oxide in the active layer is present in an amount within a range of from 0.05 percent by weight to 14 percent by weight and the gallium oxide in the active layer is present in an amount within a range of from greater than 0 percent by weight to less than fourteen by weight, each weight percent being based upon total catalyst weight. 5 . The catalyst of claim 4 , wherein the amount of aluminum oxide is within a range of from 0.05 percent by weight to 5 percent by weight and the gallium oxide is present in an amount within a range of from greater than 0 percent by weight to less than seven percent by weight, each weight percent being based upon total catalyst weight.
