1. A method of making a catalyst, the method comprising: (a) combining one or more compounds comprising an element selected from the group including alkaline earth element X and a metal element Y, wherein X is selected from the group consisting of Mg, Ca, Be, and Ba and combinations thereof, and Y is selected from the group consisting of Al, Mn, Fe, Co, Ni, Cr, Ga, B, La, P, Ti, and Zn and combinations thereof,(b) mixing the one or more compounds to form a mixture; and(c) calcining the mixture thereby forming a catalyst system, wherein the catalyst system comprises a composition represented by the formula (X1O).(X2O)a.(X3YbO4), wherein X1, X2 and X3 are alkaline earth elements selected from the group consisting of Mg, Ca, Be, and Ba and mixtures thereof, and wherein a is 0 or 1 and b is 0, 1 or 2. 2. A method of forming a catalyst system, the method comprising: (a) combining one or more compounds comprising an element selected from the group including alkaline earth element X and a metal element Y, wherein X is selected from the group consisting of Mg, Ca, Be, and Ba and combinations thereof, and Y is selected from the group consisting of Al, Mn, Fe, Co, Ni, Cr, Ga, B, La, P, Ti, and Zn and combinations thereof, and(b) precipitating the one or more compounds, thereby forming a catalyst system, wherein the catalyst system comprises a composition represented by the formula (X1O).(X2O)a.(X3YbO4), wherein X1, X2 and X3 are alkaline earth elements selected from the group consisting of Mg, Ca, Be and Ba and mixtures thereof, and wherein a is 0 or 1 and b is 0, 1 or 2. 3. The method of claim 1 wherein the catalyst system is formed on a refractory support. 4. The method of claim 1 wherein the catalyst system comprises mixed metal oxides, refractory mixed metal oxides, spinels, mixed spinels or combinations thereof. 5. The method of claim 1 wherein X1, X2 and X3 represent the same element or wherein X1 is a different element than X2 and X3. 6. The method of claim 4 wherein the catalyst system comprises mixed metal oxides represented by the formula CaO.MgO.(MgAl2O4) spinels represented by the formula MgO.(MgAl2O4), CaO (MgAl2O4), or a combination thereof. 7. The method of claim 1 wherein the step of mixing comprises dry milling, wet milling, pulverizing, or blending. 8. The method of claim 1 wherein, in the step of mixing, a solution of mixed oxide is added. 9. The method of claim 1 wherein the step of combining comprises combining at least two compounds, wherein the first compound comprising the element X is a first metal oxide precursor and wherein the second compound comprising the metal element Y is a second metal oxide precursor. 10. The method of claim 9 wherein the first and second metal oxide precursors are each separately selected from the group consisting of metal oxide, metal hydroxide, metal hydroxycarbonate, and metal carbonate, and combinations thereof. 11. The method of claim 1 wherein, in the step of mixing, the at least two compounds are mixed to form an intermediate mixture and wherein the intermediate mixture is homogeneous. 12. The method of claim 1 wherein, in the step of calcining, the one or more compounds are calcined at a temperature of at least about 900° C. 13. The method of claim 1 wherein the catalyst system is formed from at least a first compound and a second compound, wherein the first compound is a calcium source and the second compound is an aluminum source. 14. The method of claim 1 wherein the catalyst system is formed from at least a first, a second and a third compound, wherein the first compound is a calcium source, the second compound is a magnesium source and the third compound is an aluminum source. 15. The method of claim 13 wherein the aluminum source is selected from the group consisting of spent Fluid Catalytic Cracking Catalyst, equilibrium Fluid Cracking Catalyst, bauxite, gibbsite and bohemite and wherein the magnesium source is magnesite ore, brucite, dawsonite, bentonite, and dolomite and combinations thereof. 16. A method of forming a catalyst system, the method comprising calcining an anionic or cationic clay comprising at least one alkaline earth element and aluminum at a temperature of at least about 900° C., thereby forming a catalyst system, wherein the catalyst system comprises a composition represented by the formula (X1O).(X2O)a.(X3AlO4) wherein X1, X2 and X3 are alkaline earth elements selected from the group consisting of Mg, Ca, Be, and Ba and mixtures thereof, and wherein a is 0 or 1. 17. The method of claim 16 further comprising subjecting the clay to a pretreatment before the calcining step, wherein the clay is subjected to drying, extraction, washing, ion exchange, calcination or combinations thereof. 18. The method of claim 16 wherein the anionic clay is hydrotalcite or hydrotalcite-like compound or wherein the cationic clay is selected from the group including smectite, bentonite and kaolin, and combinations thereof. 19. The method of claim 16 wherein the clay is impregnated with a calcium-containing compound or magnesium-containing compound or a magnesium and calcium-containing compound forming an intermediate mixture and wherein the intermediate mixture is calcined at about 1000° C. 20. The method of claim 16 wherein the catalyst system comprises mixed metal oxides, refractory mixed metal oxides, spinels, mixed spinels or combinations thereof.
