A method of making a catalyst comprises: mixing a catalytically active component and a surfactant to form a mixture, wherein the catalytically active component comprises phosphorus; forming a gel; physically shearing the gel to form a physically sheared gel; combining the physically sheared gel with
A method of making a catalyst comprises: mixing a catalytically active component and a surfactant to form a mixture, wherein the catalytically active component comprises phosphorus; forming a gel; physically shearing the gel to form a physically sheared gel; combining the physically sheared gel with a support; and calcining the support with the physically sheared gel to form the catalyst. Another method of making a catalyst comprises: mixing a catalytically active component and a surfactant to form a mixture, wherein the catalytically active component comprises phosphorus; letting the mixture sit without mixing for greater than 1 hour to form a set mixture; subjecting the set mixture to shear to form a sheared mixture; combining the sheared mixture with a support; and calcining the support with the sheared mixture to form the catalyst.

1. A method of making a catalyst, comprising: mixing a catalytically active component and a surfactant to form a mixture, wherein the catalytically active component comprises phosphorus;forming a gel;physically shearing the gel to form a physically sheared gel;combining the physically sheared gel with a support; andcalcining the support with the physically sheared gel to form the catalyst. 2. The method of claim 1, wherein the forming comprises letting the mixture sit for greater than 1 hour without mixing. 3. The method of claim 1, wherein the catalytically active component comprises one or more elements from one or more of Groups 2, 10, 14, and 15. 4. The method of claim 1, wherein the catalytically active component comprises platinum, tin, nickel, phosphorus, calcium, or a combination comprising at least one of the foregoing. 5. The method of claim 1, wherein the support comprises a calcined alumina support. 6. The method of claim 1, wherein the total preparation time of the catalyst is 2.5 to 54 hours. 7. The method of claim 1, wherein the catalyst comprises 0.1 to 20 wt % phosphorus, 0.1 to 75 wt % tin, and 0.1 to 10 wt % of Group 1 and/or 2 metals, based upon a total weight of the catalytically active component. 8. The method of claim 1, wherein the catalyst comprises 0.2 to 25 wt % platinum, 0.2 to 5 wt % tin, 1 to 3 wt % phosphorus, 0.1 to 5 wt % calcium, 0.1 to 2 wt % chlorine, and 0.1 to 4 wt % nickel, based upon a total weight of the catalyst. 9. The method of claim 1, wherein the catalyst comprises 0.5 to 1.5 wt % platinum, 1 to 4 wt % tin, 1 to 2 wt % phosphorus; 1 to 5 wt % calcium, 0.12 to 1 wt % chlorine, 0.5 to 2.5 wt % nickel, based upon a total weight of the catalyst. 10. The method of claim 1, wherein the catalyst comprises 0.7 to 1.2 wt % platinum, 2 to 3.5 wt % tin, 1.1 to 1.5 wt % phosphorus, 1.2 to 2.0 wt % calcium, 0.12 to 0.6 wt % chlorine, 0.8 to 1.5 wt % nickel, based upon a total weight of the catalyst. 11. The method of claim 1, wherein mixture can be free of a sulfated surfactant. 12. The method of claim 1, wherein the mixture sits for greater than or equal to 2 hours without mixing. 13. The method of claim 1, wherein the mixture sits for greater than or equal to 5 hours without mixing. 14. The method of claim 1, wherein the mixture sits for greater than or equal to 8 hours without mixing. 15. The method of claim 1, wherein the catalytically active component comprises platinum, tin, nickel, phosphorus, calcium, or a combination comprising at least one of the foregoing. 16. A catalyst formed by the method of claim 1. 17. A method of making a catalyst, comprising: mixing a catalytically active component and a surfactant to form a mixture, wherein the catalytically active component comprises phosphorus;letting the mixture sit without mixing for greater than 1 hour to form a set mixture;subjecting the set mixture to shear to form a sheared mixture;combining the sheared mixture with a support; andcalcining the support with the sheared mixture to form the catalyst. 18. The method of claim 17, wherein the mixture sits until a gel forms. 19. The method of claim 17, wherein the catalyst comprises 0.1 to 20 wt % phosphorus, 0.1 to 75 wt % tin, and 0.1 to 10 wt % of Group 1 and/or 2 metals, based upon a total weight of the catalytically active component. 20. The method of claim 17, wherein the catalyst comprises 0.2 to 25 wt % platinum, 0.2 to 5 wt % tin, 1 to 3 wt % phosphorus, 0.1 to 5 wt % calcium, 0.1 to 2 wt % chlorine, and 0.1 to 4 wt % nickel, based upon a total weight of the catalyst.
