The application discloses a hydroconversion method of sulfur-containing naphtha. The method comprises the following steps: mixing the sulfur-containing naphtha with hydrogen and performing hydroconversion reaction through a hydroconversion reaction zone; the reaction effluent enters a separation system to obtain hydrogen-rich gas and a hydroconversion product through separation; the hydroconversion reaction zone is sequentially filled with a hydroconversion catalyst I and a hydroconversion catalyst II along the flow direction; and the volume ratio of the hydroconversion catalyst I to the hydroconversion catalyst II is 1:3-3:1. The method can effectively convert isomeric alkanes in the naphtha into normal alkanes, improve the ethylene raw material quality, and solve the problem of sulfur injection in the ethylene production device.

The application discloses a method for converting sulfur-containing naphtha. The method comprises the following steps: mixing the sulfur-containing naphtha with hydrogen, and then passing the mixture through a hydroconversion reaction zone; and separating a reaction product to obtain hydrogen-rich gas and a hydroconversion product, wherein the sulfur content in the hydroconversion product is 50-200 mg / kg, and the hydroconversion reaction zone is filled with at least two hydroconversion catalyst beds, and the active metal content in the catalysts decreases in sequence along the flow direction. The hydroconversion product containing a certain amount of hydrogen sulfide is used as ethylene raw material, so that the problem of sulfur injection in an ethylene production device can be solved.

Systems and methods for enhancing hydrocarbon feed fuels by using hydrogen and steam in the presence of hydroprocessing and steam catalysts within a catalytic reactor. Hydrogen can be generated and / or separated from a light gas product stream and recycled to the catalytic reactor to be used as a reactant. The catalytic reactor includes a combination of both a hydroprocessing catalyst and a steam processing catalyst. The hydroprocessing catalyst and the steam processing catalyst are each mounted directly onto a respective underlying support. The steam processing catalyst is a water splitting catalyst which facilitates the breaking of hydrogen-oxygen bonds in water to produce hydrogen. The hydroprocessing catalyst facilitates a reaction between the produced hydrogen and the hydrocarbon feed to produce hydrocarbon products
