Analysis of fluid flow at the inlet of bio-oil hydrogenation reactor
摘要
Abstract
Inlet diffuser of traditional hydrogenation reactor for petroleum products is commonly used for the mixed diffusion of gas and liquid two-phase flow. The proposed bio-oil catalytic hydrogenation reactor in this paper adopts the feeding method of upper bio-oil single phase inlet. Therefore,the diffusion effect of traditional UOC inlet diffuser applied to the bio-oil single-phase inlet was studied. The geometric modeling and meshing of the inlet fluid domain were carried out by using softwares SolidWorks and ICEM-CFD respectively, and then simulation was performed by software FLUENT. The results indicate that the spread of bio-oil behavior more uniformly and it was approximately symmetrical after passing through the inlet diffuser. At inlet single-phase flow's velocity of 0.31 m/s, when bio-oil reaches the maximum-diameter-plane, the velocity can be decreased into 0.01~0.02 m/s,meanwhile the pressure drop was small.The results can provide a reference for the optimization and improvement of the overall structure of bio-oil catalytic hydrogenation reactor.关键词
