Influence Factors of Catalyst Carrier

Studies have shown that the conversion rate of methane varies from 33.4% to 66.9% due to different carriers. Except for SiO2, the selectivity of carbon monoxide of the catalysts supported by other carriers is more than 99%.
Because the acidity and alkalinity of the carrier surface have a great influence on the activity and anti-coking ability of the catalyst, the acidity and alkalinity of the carrier surface should also be considered when selecting a catalyst carrier. It is generally believed that the relatively strong basic center on the surface of the catalyst will help to enhance the anti-coking ability of the catalyst.
The oxygen storage capacity of the carrier also has an effect on the performance of the methane partial oxidation reaction. The so-called oxygen storage capacity refers to the ability of the carrier to reversibly store and release a large amount of oxygen in accordance with the gas phase concentration. It is generally believed that a carrier with a higher oxygen storage capacity is beneficial to the partial oxidation reaction.
