A method for preparing activated carbon and composite oxide catalysts by microwave heating of coke

Abstract

The present application relates to carbon-based solid waste heat treatment and resource technology field, disclose a kind of method for preparing activated carbon and composite oxide catalyst by microwave heating coke.The volatile matter and pyrolysis coke are obtained by anaerobic pyrolysis of high-polymer organic solid waste;The volatile matter is separated into heavy tar and gas phase light component by primary condensation;The gas phase part is used for heating by reflux, and part is catalyzed by electric field coupling multi-stage pore catalyst to upgrade and prepared fuel oil and fuel gas by three-stage gradient condensation, and the uncondensed gas is all refluxed for heating;The heavy tar is cracked and prepared composite carbon source after pretreatment;The pyrolysis coke is sorted according to ash content, and the low-ash coke is activated by nitrogen and phosphorus, and the high-performance nitrogen and phosphorus co-doped activated carbon is prepared by pulse microwave treatment;The high-ash coke is coated by composite carbon source, and the carbon-coated composite oxide carrier is prepared by segmented pulse microwave calcination, which can be further loaded with copper, manganese and cerium active components to prepare catalyst.The present application realizes high-value closed-loop utilization of pyrolysis components, and the product performance is excellent, and the solid waste resource utilization rate is high.
