Question

Which catalyst is prepared by precipitation from a nitrate solution with potassium carbonate?

(a) Iron

(b) Zinc

(c) Nickel

(d) Iron

This question was addressed to me in an international level competition.

I would like to ask this question from Catalyst in section Hydrocarbon Synthesis and Hydroformylation of Unit Processes

Answer 1

Correct choice is (c) Nickel

For explanation I would say: Nickel catalysts have been prepared by precipitation from a nitrate solution with potassium carbonate in the presence of thoria and kieselguhr in the proportions 100Ni: 18ThO2: 100 kieselguhr.
