Hydrogenation of Xylenes, Ethylbenzene, and Isopropylbenzene on Ni Nanoparticles

Kinetic and thermodynamic parameters of the catalysts containing 15% of the Ni nanoparticles prepared by the levitation-jet method in the hydrogenation of xylenes, ethylbenzene, and isopropylbenzene were studied using a laboratory-made chromatographic setup. At relatively low hydrogen pressure (2 atm) and temperatures of 423–493 K, our catalysts provide a high extent of conversion of the compounds studied and selectivity concerning p -xylene.
