Abstract
Alumina of high average pore size (i.e. above 50 ) is prepared by treating an aluminium amalgam with an aqueous medium, preferably water, above 80 DEG C., and calcining the alumina hydrate so formed at above 550 DEG C., but below the temperature at which a -alumina is formed, preferably between 550 DEG and 900 DEG C. The calcination is preferably carried out for 2 to 40 hours. The hydrate is preferably dried before calcination. In an example, small pieces of high purity aluminium were immersed in 0.1 N hydrochloric acid for three hours, and then mercury equal in weight to the aluminium was added and the mixture allowed to stand for one hour with occasional shaking, after which the hydrochloric acid and excess mercury were decanted from the amalgam, which was rinsed with distilled water, and then reacted with disdistilled water at 95 DEG C. for 16 hours. The hydrate is decanted off as a slurry, filtered, dried at 80 DEG C., and calcined. Depending on calcination conditions, products ranging from specific surface area of 287 m.2/g. with an average pore diameter of 78 to 121 m.2/g. with an average pore diameter of 126 ., may be obtained. Specifications 815,512 and 815,513 are referred to.
