Description |
The textural properties of the alumina carrier playa major role in governing the performance of alumina based heterogeneous
catalysts. The regulation of the pore size distribution in the support is of paramount importance in the development
of a promising catalyst. The role of peptising agent, combustible additives and binder in regulating the mesoporosity has
been investigated using high pressure mercury porosil1)etry.Control of pore size in 18-50A radii range can be achieved by
peptising alumina monohydrate (boehmite) by 1.5% nitric acid. Additives like polyvinyl alcohol and polyethylen(:~!yc91
have broadened the mesopores while carbon black has drastically increased pores in 50-100 Arange. Addition of 10% calcined
alumina as binder has been found suitable to maintain pores <50 Aradii.
