| titleOfInvention | Non-acidic crude oil demetallizing agent with core-shell structure and preparation method and application thereof |
| abstract | The invention relates to a non-acidic crude oil demetallizing agent with a core-shell structure, which is prepared from an organic-inorganic hybrid material with a core-shell structure, wherein the core is a nano or micron inorganic particle, and the shell layer is an amphiphilic polymer with functional groups grafted on chains and having strong metal chelating capacity. The preparation method of the demetallization agent comprises the following steps: preparing nano or micron inorganic particles; preparing an intermediate; preparing a demetallization agent; the core-shell structure of the demetallization agent has high compatibility with metal ions and high space utilization rate, and improves the chelating capacity of a chelating group; is a non-acidic crude oil demetallization agent suitable for removing calcium, nickel and vanadium in crude oil: the nickel removal rate is more than 65 percent, the vanadium removal rate is more than 45 percent, the calcium removal rate is more than 60 percent, and the catalyst does not contain phosphorus, is environment-friendly and has the advantages of small dosage, non-acidity, no corrosion to equipment and the like. |
