Versuchsvorschrift

Lanthanum nitrate hexahydrate 2.99 g and cerium nitrate hexahydrate 0.95 g were dissolved in 12.5 g of water to provide an aqueous solution of lanthanum nitrate-cerium nitrate mixture. Fifteen (15.0) g of silica gel (CARIACF 30® manufactured by Fuji Devison) was impregnated with the solution prepared as described above and dried at 120° C. in air, followed by a sequential calcination in air at 500° C. for 5 hours and in nitrogen at 500° C. for 5 hours. Thus lanthanum and cerium oxides as carried on the silica gel were obtained. The product was labelled Catalyst (8). This support type catalyst contained 7.5 wt % of lanthanum oxide and 2.5 wt % of cerium oxide, and had a specific surface area of 109 m2 /g.
