First, 60 g of hydrated alumina (trade name: Disperal HP14 available from Sasol Ltd.) was added to 800 g of pure water, and 1.29 g of magnesium acetate tetrahydrate (element content of Mg/element content of Al=0.006) was added to the resultant mixture. The resultant dispersoid was dried by a spray-drying method to obtain hydrated alumina 1 which magnesium acetate adhered to. The drying temperature (gas phase temperature) was 170° C. The acid site strength of the hydrated alumina 1 was measured by temperature-programmed desorption (TPD) that determines surface activity using ammonia gas. As a result, the presence of acid sites was not confirmed, and it was found that magnesium acetate adhered to hydrated alumina.
