Abstract: By studying the main factors affecting the space utilization of hydrogenation reactor, from the perspective of maximizing the space utilization of hydrogenation reactor, the technologies of improving the space utilization of hydrogenation reactor are developed, including the reactor internals packaged technology and/or the optimization of the teeth spherical catalyst technology. On the basis of ensuring the overall efficiency and operation cycle of hydrogenation reaction, the space utilization rate of hydrogenation reactor is increased by 10%~23%.The new internals packaged technology can solve the engineering amplification problems of uneven material distribution and local hot spots, and make the space utilization rate of the reactor increase by 5.3%~14.5% compared with the traditional technology. The optimum technology of teeth spherical catalyst can increase the space utilization rate of the reactor by 4.7%~8.5%, increase the processing capacity of crude oil, and bring significant economic benefits.
