Resumo: | Different activated carbons and manganese-modified activated carbons were prepared as deoxidizers for the low-concentration coalbed methane deoxidation. The results show that the deoxidation performance of the different activated carbons is affected by raw materials for preparation of deoxidizers. One type of activated carbon exhibited the best performance of oxygen removal, due to the relatively low ash content and better adsorption performance. Experimental results show that the manganese-modified deoxidizers exhibit an excellent deoxidation efficiency at low temperature. At 200 ºC, one kind of manganese-modified activated carbons decreased the oxygen content to less than 1 vol%, which could maintain about 600 min. This indicated that the addition of manganese greatly improved the reactivity of oxygen with activated carbon. Characterization results demonstrated that the physical structure and species types of oxygen of activated carbons, and manganese have important effects on the activity of deoxidizers in different temperature ranges. |
