Ni/Alumina catalyst are used for reactions including hydrogenation of fatty acid

Question

Ni/Alumina catalyst are used for reactions including hydrogenation of fatty acids and olefins and for conversion of CO and H2 to methane. The catalysts used for the former reaction may contain 20 wt% Ni. Assume that 20g of such a catalyst is to be prepared with Ni(NO3)2 by incipient wetness techniques, whereby just enough solution is used to fill the pore of the support. If the pore volume of the alumia is 0.6 cm3/g. How much Ni(NO3)2 solution should be used and what is the required concentration?

Explanation / Answer

For the given catalyst,

20 g of 20 wt% catalyst would need = 2 g of Ni

182.703 g has 58.7 g of Ni,

so, for 2 g Ni we would take = 2 x 182.703/58.7 = 6.22 g Ni(NO3)2 would be required

Volume of Ni(NO3)2 solution required = 6.22 g x 0.6 cm^3/g = 3.732 ml

concentration of solution = 6.22/182.703 x 0.003732 = 9.12 mol/L
