Abstract

The invention discloses a liquid phase hydrogenation system based on a liquid phase filling reactor. The liquid phase hydrogenation system comprises a supplementary hydrogen compressor, a feeding pump, a heating furnace, a reactor and a circulation pump, wherein the reactor is connected with the heating furnace; the supplementary hydrogen compressor is connected with the reactor; raw materials preheated by the heating furnace enter the reactor; the raw materials in the reactor and supplementary hydrogen take hydrogenation reaction; the circulation pump is arranged between the an outlet of the reactor and the heating furnace; the circulation pump pumps unreacted raw materials in the reactor into the heating furnace; secondary heating is performed; the raw materials enter the reactor again for taking complete reaction. A liquid phase hydrogenation technology is based on the liquid phase filling reactor; product liquid is recycled so that quantity of hydrogen dissolved in mixed raw materials is much higher than the hydrogen quantity required for the reaction.

Description

technical field [0001] The invention relates to the technical field of liquid-phase hydrogenation, in particular to a liquid-phase hydrogenation system based on a liquid-phase filled reactor. Background technique [0002] At present, the global oil refining industry is facing the status quo of poor crude oil quality, the difficulty and cost of the oil refining industry are facing challenges, and with the improvement of environmental protection requirements, the quality requirements of products are becoming increasingly stringent. Therefore, vigorously developing the hydrogenation process, continuously improving efficiency, and reducing energy consumption are the best choices to deal with the new situation. [0003] In a traditional fixed-bed process, the reaction unit is filled with a large amount of gas, and the liquid is sprayed down onto the catalytic bed. The hydrogen used in the reaction is dissolved in the liquid instead of being circulated as a gas. Therefore, the ca...
