a. Define Shape Selective catalysis. Name the Zeolite Catalyst used to convert alcohols to gasoline in petroleum industry

Text Solution

Verified by Experts

(b) Zeolite catalyst is ZSM -5.
(b)The process of conversion of freshly prepared precipitate into a colloidal solution by adding an electrolyte containing the common ion is called peptisation.
Example: Ferric hydroxide sol `[Fe(OH)_(3)]`,
is prepared by adding ferric chloride to freshly prepared precipitate of `Fe(OH)_(3)`.
(c) `x/m=K.p^(1/(n))`
x is mass of the gas adsorbed.
m is mass of the adsorbent.
p is pressure.
`K_(1)` and n are constants.
