Abstract
1347106 Alumina hydrogel SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 19 April 1971 [16 Feb 1970] 21798/71 Heading C1A An alumina hydrogel is precipitated by concurrently reacting an aqueous solution of an aluminium salt with an aqueous solution of an aluminate at pH 8À5-10À5, and 20-40 C., to a solids content of the reaction mixture of up to 40 gm/l. and the resulting hydrogel is separated and washed with 0À005-1 M. ammonium carbonate or bicarbonate solution which is free from alkali metal ions, and then dried and calcined, to give a product having the following characteristics: Bulk density 0À5-0À8 gm/c.c. Surface area 200-350 m<SP>2</SP>/gm. Pore volume 0À4-0À7 c.c./gm. Average pore diam. 60-120 (<1% pores below 30 and <1% pores greater than 350 , at least 70% pores 40-160 ). An alkali metal carbonate may be added before or after precipitation. The precipitated slurry preferably contains 20-40 gm/litre solids. Calcination is preferably performed at 450- 650 C. in a non-reducing atmosphere. In a modification the reaction is performed in the presence of an alkali metal carbonate, to a solids content of up to 80 gms/l.
