Method and system for producing hydrogen oil by converting ultrahigh-temperature fly ash

The invention discloses a method and a system for producing hydrogen oil by converting ultra-high-temperature fly ash, and the system for producing hydrogen oil by converting ultra-high-temperature fly ash is used for mixing fly ash and urban garbage according to a certain proportion, granulating and molding, and then carrying out ultra-high-temperature gasification to generate molten slag and mixed gas. The mixed gas is subjected to reforming and water-gas shift under the action of a high-selectivity catalyst to generate hydrogen and carbon dioxide, the hydrogen is subjected to a gas purification section to prepare purified hydrogen, and the purified hydrogen and a liquid organic hydrogen storage carrier are subjected to a hydrogenation reaction to obtain hydrogen oil which can be stored at normal temperature and normal pressure. According to the comprehensive utilization system for the fly ash, various pollution sources generated in the fly ash treatment process can be fundamentally eradicated, the requirem
