A mesoporous aluminophosphate material includes a solid aluminophosphate composition modified with at least one element selected from zirconium, cerium, lanthanum, manganese, cobalt, zinc, and vanadium. This mesoporous aluminophosphate material has a specific surface area of at least 100 m2/g, an average pore size less than or equal to 100 Å, and a pore size distribution such that at least 50% of the pores have a pore diameter less than 100 Å. The material can be used as a support for a catalytic cracking catalyst. Additionally, a method for making such a mesoporous aluminophosphate material is disclosed. The method, which preferably avoids use of organic reagents or solvents, includes providing an aqueous solution containing an inorganic phosphorus component; an inorganic aluminum containing component; and an inorganic modifying component containing at least one element selected from zirconium, cerium, lanthanum, manganese, cobalt, zinc, and vanadium. A solid mesoporous aluminophosphate material is formed in the solution by adjusting the pH of the solution to the range of 7 to 12 and is then recovered.
A mesoporous aluminophosphate material, comprising a solid aluminophosphate composition modified with at least one element selected from the group consisting of zirconium, lanthanum, manganese, cobalt, and zinc, wherein the mesoporous aluminophosphate material has a specific surface area of at least 100 m2/g, an average pore diameter less than or equal to 100 Å, and a pore size distribution such that at least 50% of the pores have a pore diameter less than 100 Å and further, that 10%-56% of the pores have a pore diameter of 50-100 Å, while 1%-35% of the pores have a pore diameter of >150 Å.
A mesoporous aluminophosphate material, comprising a solid aluminophosphate composition modified with at least one element selected from the group consisting of manganese, cobalt, and zinc, wherein the mesoporous aluminophosphate material exhibits hydrothermal stability after steaming at 1500° F. (815° C.) for four hours with 100% steam at atmospheric pressure by maintaining a surface area of at least 81 m2/g, has a specific surface area of at least 100 m2/g, an average pore diameter less than or equal to 100 Å, and a pore size distribution such that at least 50% of the pores have a pore diameter less than 100 Å, and further that 10%-56% of the pores have a pore diameter of 50-100 Å, while 1%-35% of the pores have a pore diameter of >150 Å.
