Patent ID: 10576457

Abstract:
The present disclosure relates to an alumina having a surface area in the range of 330-400 m2/g, a pore volume in the range of 1.2-1.7 cc/g, and an average pore diameter in the range of 125-160 Å. The present disclosure also relates to alumina extrudates having a diameter in the range of 1 mm to 3 mm, a surface area in the range of 300-360 m2/g, a pore volume in the range of 0.8-1.3 cc/g and pore diameter in the range of 90-130 Å with a crushing strength in the range of 1-2.5 daN/mm. Further, the present disclosure relates to a process for the preparation of alumina and alumina extrudates. The alumina extrudates can be used as a support for catalyst preparation or as a catalyst or adsorbent in various processes. The process of the present disclosure enhances metal loading capacity, has better metal dispersion, and exhibit delay in deactivation of the catalyst due to mouth pore plugging.
