OBTAINING PALLADIUM NANOPARTICLES AND THEIR APPLICATION AS CATALYST IN HYDROGENETION OF VEGETABLE OIL

Abstract

Palladium nanoparticles are obtained by reduction of palladium chloride with sodium borohydride. The obtained palladium particles are characterized by intense optical absorption in the region of λ=350 nm, which indicates the formation of particles with a size of 10-50 nm. Palladium nanoparticles are immobilized on activated carbon to increase the contact surface. The catalytic activity of the obtained catalyst has been studied in the hydrogenation reaction of vegetable oil at convection and microwave heating. It has been found that at the content of 1 % of the oil mass catalyst, a higher melting product is formed (380C. Decrease of temperature and duration reduction of the process results in low melting margarines of MLF and MLB grades). The use of microwave technology (power 700 W) reduces significantly the duration of the process (up to 30 minutes) to form a product with the melting point of 340C.
