1 Introduction In order to obtain high-quality petroleum processing products or increase petrochemical raw materials and middle distillates, as well as to meet the needs of deep processing of high-sulfur crude oil and inferior crude oil and to improve the environmental conditions, hydrogenation has taken place in the modern petroleum processing industry Process equipment. In the meantime, significant advances have been made in the design and manufacturing of hot wall hydrogenation reactors for key equipment in hydrogenation plants. Hot-wall hydrogenation reactor long-term at high temperature, high pressure and Pro
