The invention provides a gasoline desulfuration and deodorization process, which adopts a fiber liquid film mass transfer mode and a fixed bed reactor series connection mode to conduct gasoline desulfuration and deodorization purification. Gasoline is firstly contacted with alkali liquor in a fiber liquid film device, hydrogen sulfide and a large part of mercaptan in the gasoline are extracted to enter the alkali liquor and then are sent to a fixed bed reactor; under effects of oxidation air and activating agents, remained mercaptan is oxidized to be corresponding disulphide; and finally the gasoline desulfuration and deodorization purification is achieved. The gasoline desulfuration and deodorization process can not only improve efficiency of gasoline alkali wash in advance, but also achieve the purpose of effectively reducing equipment investment of a fixed bed, reducing use amounts of catalytic agents and the activating agents, and effectively guaranteeing product sulphur contents to reach the standard and the like.
