The invention discloses a refinery gas hydrogenation combination method. The refinery gas hydrogenation combination method comprises the following steps of (a) adopting an aviation fuel raw oil separately or mixing the aviation fuel raw oil with a circulating oil, then mixing the aviation fuel raw oil or the mixture of the aviation fuel raw oil and the circulating oil with a hydrogen gas or the hydrogen gas and a refinery gas, enabling the mixture to enter a hydrogenation catalyst bed layer for reaction under hydrogenation operation conditions, wherein the catalyst bed layer is disposed in multiple layers, and a gas-dissolving device is disposed between the adjacent catalyst bed layers; (b) mixing the refinery gas and/or the hydrogen gas, then enabling the mixed gas to enter any of the gas-dissolving devices disposed between the adjacent catalyst bed layers, mixing the mixed gas with a reaction material flow from the previous catalyst bed layer, and then enabling the mixture to enter the next catalyst bed layer for reaction; and (c) separating hydrogenation reaction effluent into a gas phase and a liquid phase, continuously separating the gas phase obtained by separation to obtainthe hydrogen gas and the hydrotreated refinery gas, and fractionating the liquid phase obtained by separation to obtain a naphtha product and a diesel product, and returning part of the hydrogenationreaction effluent and/or the liquid phase obtained by separation to the hydrogen-dissolving device as the circulating oil. With the method, the refinery gas can be hydrotreated and the high-quality aviation fuel can be produced simultaneously.
