ABSTRACT:
A heat resistant transition alumina produced by mixing aluminum sulfate and a lanthanum compound, heating the mixture, and then thermally decomposing the mixture, and a process for producing the heat resistant transition alumina. The heat resistant transition alumina has a high BET specific surface area, and an excellent heat resistance as exhibiting a less reduction in the BET specific surface area even under temperatures of 1000.degree. C. or higher, and exhibits a high porosity even when coated onto other catalyst supports having a lower specific surface area, and is producibile at a lower cost.
