CO2 Hydrogenation over Ru/χ-Al2O3 Catalyst

Kanyanat Jeenjumras, Sunthon Piticharoenphun, Okorn Mekasuwandumrong

Abstract

The hydrogenation of CO 2 was investigated over Ru/χ-Al 2 O 3 catalyst prepared by thermal decomposition of gibbsite which was followed with impregnation using different types of ruthenium precursors. The performance of the catalysts was examined by the temperature programmed reaction of CO 2 with H 2 . The Ru/χ-Al 2 O 3 catalyst prepared using ruthenium (III) nitrosyl nitrate solution as the Ru source (RNN) exhibited the best performance, compared to other Ru precursors. The physiochemical properties of each catalyst were characterized using XRD diffraction, N 2 physisorption and H 2 chemisorption.
