Question

Give some features of catalysis by Zeolites

Answer 1

Zeolites are alumino-silicates that are micro-porous in nature. Zeolites have a honeycomb-like structure, which makes them shape-selective catalysts. They have an extended 3D-network of silicates in which some silicon atoms are replaced by aluminium atoms, giving them an Al-O-Si framework. The reactions taking place in zeolites are very sensitive to the pores and cavity size of the zeolites. Zeolites are commonly used in the petrochemical industry.

Answer 2

Answer:

Zeolites are alumino-silicates that are micro-porous in nature. Zeolites are also shape- selective catalysts as they have a honeycomb-like structure. Some silicon atoms are replaced by aluminium atoms in the extended 3D-network of silicates, giving them an Al−O−Si framework. The pores and cavity size of the zeolites makes the reactions very sensitve. Zeolites are commonly used in the petrochemical industry.
