Moreover, the catalyst properties can satisfy the requirement of guarantee value during calibration, and the desulfurization percent and the denitrification percent are 97.1% and above 66.7% respectively.
The effect of reaction conditions and catalyst performances on the dehydrogenation of 1,4-butanediol toγ-Butyrolactone over the CuO-ZnO-Al_2O_3 catalysts at normal pressure was studied and the stability of catalyst was also observed.
The resistance to hydration of the sulfur tolerance shift catalyst with γ Al 2O 3 as the support was studied under the simulated new process conditions in domestic chemical fertilizer industry,and the influence on catalyst performances after the hydration of the support was also presented. It provides some valuable information for selecting sulfur tolerance shift catalyst used in the new process.
The results show that the property of catalyst depends highly on its precursor composition. The catalyst made from HZ precursor has a high activity. The catalyst made from FC precursor has high thermal stability.
This article analyzes the effect of sing factor on reaction of N－pentane isomerization, and obtains the optimum reaction conditions and results for N－pentane isomerization by using orhtogonal method． The test for the activity and stability of the Cat． Was made in 100 mL－test facility for 1 000 hours, which shows that the property of catalyst for the two non－precious metals mordenite isomerization is stable．
The catalyst performance was tested on a real lean-burn gasoline engine.
It was demonstrated that the CO/CO2 addition to methane effectively improves the catalyst performance by keeping a higher methane conversion and selectivities of benzene formation in the prolonged time-on-stream.
Criteria for evaluation of the catalyst performance under conditions of hydrodesulfurization of various kinds of crude are proposed.
The catalyst performance was judged from the molar radioactivity of [6-3H]uracil and [5-3H]uracil formed by catalytic hydrogenation with gaseous tritium of orotic acid and 5-bromouracil, respectively.
