Abstract
The present invention relates to a micro-interface strengthening reaction system and method for heavy oil hydrogenation preparation of ship fuel, including a liquid phase feed unit, a gas phase feed unit, a micro-interface generator, a fixed-bed reactor and a separation tank. The present invention may reduce the pressure during the reaction by 10-80% while ensuring the efficiency of the reaction by breaking the gas to form micro-sized micro-bubbles and making the micro-bubbles mix with heavy oil to form an emulsion to increase the area between the gas and the liquid phase and to achieve the effect of enhancing mass transfer in a lower preset range. And, the present invention greatly enhances the mass transfer, so that the gas-liquid ratio can be greatly reduced. Also, the method of the present invention has low process severity, high production safety, low product cost per ton, and strong market competitiveness.
