Preparation method and application of MgO (111) load nickel-base catalyst

Abstract

The invention belongs to a catalyst preparation technology field of reforming methane with carbon dioxide to produce synthesis gas, and particularly discloses a preparation method and application of MgO (111) load nickel-base catalyst. The catalyst is synthesized by a step of carrier synthesis and a step of Ni/MgO (111) preparation. The carrier is prepared by dissolving magnesium ribbon into a absolute methanol, adding anisyl alcohol and stirring, adding a water methanol solution dropwise under stirring, putting the hydrolyzed mixture into a high pressure reactor, leading argon into the reactor to replace the atmosphere, and then pressurizing to 1.0 MPa, reacting at the temperature of 265 DEG C, cooling and putting the obtained product into a tubular furnace, and calcinating the product; and the Ni/MgO (111) is prepared by immersing the carrier in an acetylacetone nickel solution uniformly, and calcinating for 5 h at the temperature of 650 DEG C after drying. The results of using the catalyst for catalyzing the reforming reaction of methane and carbon dioxide show that the catalyst has good activity and stability and enables the conversion rate of both CH4 and CO2 to be over 85%, and that the catalyst activity can stably maintain for 200 h without obvious inactivation.

AI Technical Summary

Benefits of technology

This patented technology has several benefits compared to previous methods such as adding specific structures or modifying existing ones. It also includes strong interactions between different materials like iron (II), manganese (III)) cathode material, magnesium hydroxyl group donors, etc., which helps improve its effectiveness over time without losing their original properties during use.

Problems solved by technology

This patented technical solution discusses various ways to improve the efficiency or performance of traditional methods involving reactants like hydrogen gas production from natural sources through processes that use fossil fuels. However, these techniques often result in emissions containing harmful pollutants which may affect global environmental quality. Non-polluting transition materials based on iron carbides could provide an alternative approach without causing negative effects associated with expensive precious metallic catalyst systems.
