This invention is directed to star shaped alumina extrudates with a pore
volume in the pores of a diameter over 1000 nm, as determined by mercury
porosity, of at least 0.05 ml/g and a total pore volume between 0.5-0.75
ml/g. The extrudates have a length of between 2-8 mm, a length to
diameter ratio of between 1-3, a side crushing strength of at least 50 N
and a bulk crushing strength of at least 1 MPa.
