ABSTRACT OF THE DISCLOSURE 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 resist- ance as exhibiting a less reduction in the BET specific surface area even under temperatures of 1000°C or higher, and exhibits a high porosity even when coated onto other catalyst supports having a lower specific surface area, and is producible at a lower cost.
