Abstract

The invention discloses a full-fraction catalytic gasoline selective hydrodesulfurization device, and relates to the technical field of desulfurization processing. The full-fraction catalytic gasoline selective hydrodesulfurization device comprises a base; desulfurizers are fixedly connected to the left side and the right side of the top face of the base; connecting pipes are fixedly connected to the top faces of the two desulfurizers, a classification box is fixedly connected to the upper ends of the two connecting pipes, a feeding pipe is fixedly connected to the top face of the classification box, and a motor is fixedly connected to the left side of the classification box; and a screening device is arranged in the classification box, and a feeding device is arranged in the classification box. Through the arrangement of the screening device, a filter frame vibrates to filter raw materials, the raw materials with fine texture are discharged into a desulfurizer on the left side through the connecting pipe, and rough raw materials are left in the filter frame, so that the classification of the raw materials is completed, and different hydrogen is added for the classified raw materials to desulfurize; therefore, the utilization rate of the raw materials is increased, and the environment-friendly and energy-saving effects of the device are improved due to waste of the raw materials.

Description

technical field [0001] The invention relates to the technical field of desulfurization processing, in particular to a device for selective hydrodesulfurization of full fraction catalytic gasoline. Background technique [0002] Catalytic gasoline has the characteristics of low sulfur and high octane number. It is one of the main blending components of gasoline in my country. The sulfur content is about 200-600mg / kg. When producing National III gasoline, it is generally blended with other low-sulfur components Then the quality requirements can be met. However, in the context of continuous upgrading of the quality of gasoline products, especially after gasoline has begun to implement the National IV and National V standards, it is imperative to desulfurize catalytic gasoline. The current catalytic gasoline hydrodesulfurization process basically uses heavy gasoline alone. Hydrogen process, gasoline is pre-fractionated, cut into light and heavy gasoline, heavy gasoline is hydrode...
