HOLLOW CATALYST CARRIER AND HOLLOW CATALYST MADE OF TRANSITION-ALUMINA AND PROCESS FOR PRODUCTION THEREOF Abstract of the Disclosure: The invention relates to a hollow catalyst carrier and hollow catalyst made of a transition-alumina (e.g. y- alumina). The catalyst carrier is a calcined product having a pipe-like or multi-cell structure and having a very large void ratio (i.e. not less than 3 %), a very large specific surface area (i.e. not less than 5 m2/g), a bulk density of 0.8 to 1.8 g/cm3, a compressive strength in the extrusion direction of not less than 20 kg/cm2, and at least one hole in the ex- trusion direction. The carrier is produced by subjecting a powder containing a rehydratable alumina to an extrusion molding step, rehydrating the molded product and calcining it. The hollow catalyst carrier has very good properties for carry- ing catalytically active components thereon and has very good mechanical strength.
