Zirconium dioxide based catalysts were synthesized by mechanical mixing method and evaluated for the direct synthesis of isobutene and isobutane (i-C 4 ) from CO hydrogenation. The experiments of temperature-programmed desorption of ammonia and carbon dioxide indicated that both the amount of acid-base sites and the strength of acid and base of the catalysts varied with the incorporation of...
The promoting effects of various calcium salts on the activity and selectivity of ZrO 2 in isosynthesis were studied in this work. Calcium salts were added into zirconia by mechanical mixing methods. Catalytic tests were performed under relatively mild operation conditions (673K, 650h -1 , 5.0MPa). CaF 2 and CaSO 4 were found to be effective additives, which could...
