Description

[0002] Hydrocracking is one of the most important refining methods in petroleum products. However, in the existing gasoline hydrogenation refining process, hydrogen is generally transported to the reaction device to contact with gasoline. In order to enhance the dissolution effect of gasoline and hydrogen in the hydrogenation process, heating is performed. The traditional heating method is only to install a heating plate at the bottom, and the heating efficiency and heating uniformity are general.

[0003] After searching, a gasoline hydrogenation refining device in Chinese patent document (authorized publication number CN215975669U) can drive the rotating gas pipe and the rotating oil pipe to rotate by starting the motor while adding hydrogen into the rotating gas pipe through the first hydrogen inlet pipe and adding gasoline into the rotating oil pipe through the gasoline inlet pipe. While rotating, gasoline and hydrogen contact and dissolve and crack each other, and finally are thrown out of the rotating oil pipe into the reaction tank body. The gasoline in the reaction tank body is stirred by the spiral blade, and the gasoline moves downward along the rotating spiral blade during the stirring process, so that hydrogen can be uniformly dissolved in the gasoline. At the same time, the setting of the electric heating plate can further improve the dissolution rate of gasoline and hydrogen, improve the hydrogenation reaction effect, ensure complete gasoline cracking, and after the hydrogenation cracking is completed, open the oil outlet valve to make the refined gasoline be pumped to the product tank for temporary storage. In order to enhance the dissolution effect of gasoline and hydrogen in the hydrogenation process, heating is performed. The heating method is only to install a heating plate at the bottom, and the heating efficiency and heating uniformity are general. UTILITY MODEL CONTENTS
