Abstract :
The 1-butyl-3-methyl imidazolium hydroxide ionic liquid (BMIm[OH]) is loaded on commercial low surface area Pd-Ag/α-Al_2O_3 solid catalyst to enhance its selectivity in acetylene partial hydrogenation. Different experimental techniques such as atomic absorption spectroscopy, BET and gas chromatography have been utilized to characterize chemical, structural and catalytic properties of the catalyst. Additionally, FT-IR spectra are collected to study the synthesized ionic liquid. The selectivity and activity of the fresh and used catalysts are compared for both ionic liquid free sample and loaded one. Results revealed that the 13.7% Ethylene to Ethane ratio improvement over commercial catalyst is achievable successively through 0.2 Wt.% of BMIm[OH] ionic liquid loading.
