A hydrogenation catalyst and a manufacturing method therefor. The manufacturing method at least comprises: (1) contacting a first active metal component and a first organic complexing agent with a carrier to obtain a composite carrier; (2) calcining the composite carrier to obtain a calcined composite carrier, the total content of carbon in the calcined composite carrier being less than 1 wt%; and (3) contacting a second organic complexing agent with the calcined composite carrier to obtain a hydrogenation catalyst. The hydrogenation catalyst has excellent hydrogenation desulfurization activity and hydrogenation denitrification activity, and shows significantly extended catalyst service life. |
