Abstract
Official abstract text for this publication.
There is provided a dehydrogenation catalyst for producing olefins from alkane gases, in which a metal active component is supported on an alumina carrier containing boron. There is provided a method for preparing a dehydrogenation catalyst for producing olefins from alkane gases. The method includes impregnating alumina in a boron-containing solution and calcining it to provide a boron-alumina carrier; providing a solution containing the metal active component; impregnating the boron-alumina solution in the solution containing the metal active component and drying it; and calcining the boron-alumina carrier on which the metal active component is supported at 700° C. to 900° C.
First claim
Opening claim text (preview).
1 . A dehydrogenation catalyst for producing olefins from alkane gases, in which a metal active component is supported on an alumina carrier containing boron. 2 . The dehydrogenation catalyst of claim 1 , wherein the boron is supported in an amount of 0.1 to 2 wt % based on the alumina. 3 . The dehydrogenation catalyst of claim 2 , wherein the boron is supported in an amount of 0.5 to 2 wt % based on the carrier. 4 . The dehydrogenation catalyst of claim 1 , wherein the metal active component essentially includes cobalt. 5 . The dehydrogenation catalyst of claim 4 , wherein the cobalt is supported in an amount of 1 to 5 wt % based on the alumina. 6 . The dehydrogenation catalyst of claim 4 , wherein the metal active component further includes platinum. 7 . The dehydrogenation catalyst of claim 6 , wherein the platinum is supported in an amount of 0.001 to 0.05 wt % based on the alumina. 8 . A method for preparing a dehydrogenation catalyst for producing olefins from alkane gases, the method comprising the steps of: impregnating alumina in a boron-containing solution and calcining it to provide a boron-alumina carrier; providing a solution containing the metal active component; impregnating the boron-alumina solution in the solution containing the metal active component and drying it; and calcining the boron-alumina carrier on which the metal active component is supported at 700° C. to 900° C. 9 . The method of claim 8 , wherein the boron-alumina carrier is calcined at 400 to 600° C. 10 . The method of claim 8 , wherein the boron is supported in an amount of 0.1 to 2 wt % based on the alumina. 11 . The method of claim 10 , wherein the boron is supported in an amount of 0.5 to 2 wt % based on the carrier. 12 . The method of claim 8 , wherein the metal active component essentially includes cobalt. 13 . The method of claim 12 , wherein the cobalt is supported in an amount of 1 to 5 wt % based on the alumina. 14 . The method of claim 12 , wherein the metal active component further includes platinum. 15 . The method of claim 14 , wherein the platinum is supported in an amount of 0.001 to 0.05 wt % based on the alumina. 16 . A continuous reaction-regeneration olefin production method including the catalyst of claim 1 . 17 . The continuous reaction-regeneration olefin production method of claim 16 , wherein the reaction temperature is 560 to 640° C. 18 . The continuous reaction-regeneration olefin production method of claim 16 , wherein alkane, which is a raw material in the olefin production method, has a flow rate (weight hour space velocity) of 4 to 16 h −1 .
