Porous hydrated alumina prepn. - with controlled pore size

Porous particles of hydrated alumina having a given pore size are prepd. by pptn. from an aq. soln. of alkali aluminate, by addn. of sufficient acid, the pore size being controlled by keeping the soln. at a fixed temp. closely controlling the mean pore size. Used as a catalyst support both with smal...

Zusammenfassung:	Porous particles of hydrated alumina having a given pore size are prepd. by pptn. from an aq. soln. of alkali aluminate, by addn. of sufficient acid, the pore size being controlled by keeping the soln. at a fixed temp. closely controlling the mean pore size. Used as a catalyst support both with small and large pores.
