Effect of Magnesium Oxide MgO on Sulfur Tolerant Shift Catalyst
Magnesium Oxide MgO is an inorganic salt chemical. Magnesium Oxide MgO products are used in sulfur-resistant shift catalysts. The addition and addition methods of Magnesium Oxide MgO have certain effects on the strength and activity of sulfur-resistant shift catalysts. Magnesium Oxide MgO can not only improve the CO shift activity of the catalyst, especially the medium temperature shift activity, but also help to improve the strength and strength stability of the catalyst, and inhibit or reduce the possibility of the hydration phase transition of the support.
Adding an appropriate amount of Magnesium Oxide MgO additive to the carrier can improve the adsorption performance of the catalyst for water vapor and hydrogen sulfide, and is beneficial to improve the CO conversion activity of the catalyst. The crushing strength of the catalyst support increases significantly with the increase of the amount of Magnesium Oxide MgO added. The strength of the catalyst can be significantly improved and the specific surface of the catalyst is raised.
