Abstract
A radial reactor for utilization for catalytic reactions of gaseous or liquid feedstreams including an annular catalyst bed, wherein the material contained within the catalyst bed includes an active catalyst material, contained within an outer ring-shaped layer of the catalyst bed, and a generally inert material, contained within an inner ring-shaped layer of the catalyst bed, wherein the generally inert material includes a potassium-containing compound, such as potassium oxide, hydroxide, carbonate or bicarbonate.
Claims19
A process for the nonoxidative dehydrogenation of an alkylaromatic feedstream comprising passing a fluid alkylaromatic feedstream into a radial reactor comprising a catalyst bed having at least a first layer loaded with a potassium-containing supported compound and having at least a second layer loaded with a dehydrogenation catalyst, such that said fluid contacts said first layer and then contacts said second layer before said fluid exits said catalyst bed.
A process for the nonoxidative dehydrogenation of an alkylaromatic feedstream that comprises loading a radial reactor having a catalyst bed that defines a vertical inner layer and a vertical outer layer with an inert material containing a potassium compound in the vertical inner layer and with a dehydrogenation catalyst material in the vertical outer layer, and then introducing a fluid feedstream comprising ethylene into said radial reactor though an inlet and forcing said fluid into a central core of said radial reactor and then through an inner screen and then through said vertical inner layer and then through said vertical outer layer and then through an outer screen and into a channel that flows into a headspace and exits said radial reactor through an outlet.
