Abstract:
Biodiesel or fatty acid methyl esters (FAMEs) can be produced from vegetable oils or animal fats with methanol via the transesterification reaction. The fatty acid composition of feedstock has a significant impact on the properties of the biodiesel obtained because the fatty acid profile in the feedstock is identical to that of the resulting biodiesel. The main drawbacks of biodiesel properties are oxidative stability and cold flow properties [1]. Partial hydrogenation of polyunsaturated FAMEs to monounsaturated FAMEs may provide substantial solutions to these problems [2]. The mesoporous molecular sieve MCM-41 has attracted much attention because of their uniform mesopores with pore diameter in the range of 2-2.5 nm and high surface area [3]. Our previous study successfully synthesized MCM-41 with high surface area and uniform crystallization from commercial silica by microwave radiation-assisted hydrothermal synthesis in a short synthesis period. The main aim of this work is to investigate the effect of various metal loadings in the range of 0.5 to 2 wt. % on the catalytic activity over Pd/MCM-41 catalysts for partial hydrogenation of polyunsaturated FAMEs. It can be verified that 2 wt. % Pd/MCM-41 presented the highest reactivity and oxidative stability.
