Bimetallic Ag-Ni on SiO2 Catalyst for Kapok Seed Oil Hydrogenation

Abstract

Bimetallic Ag-Ni on SiO2 prepared by precipitation was used as catalyst for kapok seed oil hydrogenation. The catalytic-transfer hydrogenation (CTH) was performed in a batch reactor at 76oC, catalysts loadings of 1-4%w, using potassium formate as hydrogen donor. The best condition for kapok seed hydrogenation is at 76o C temperature, 16 hours reaction time, with 1% catalyst, 10 M potassium formate, and 2:1 ratio of potassium formate to the double bond. CTH using higher concentration of potassium formate could eliminate almost all of the cyclopropenoid acid. The bimetallic Ag-Ni catalyst is proposed as a promising candidate for selective edible oil hydrogenation.
