摘　　要：针对50kt/a渣油临氢热裂化中型反应器,应用欧拉-欧拉模型,运用CFD模拟方法,对比了浆态床的普通鼓泡反应器、强制外循环反应器、内环流反应器和外环流反应器的流体力学性能,得到了这4种反应器内气浆两相流体的流体力学规律。通过对比4种反应器内气浆两相流体的表观速度、流动方向和体积分数分布等流场信息,初步确定强制外循环反应器和外环流反应器更适合渣油临氢热裂化反应的反应器形式。The flowing behaviors of both gas phase and slurry phase in four types of slurry reactors of bubble column, inner loop reactor, forced recycling reactor and outer loop reactor were simulated and compared by Euler-Euler model with CFD in accordance with the development of a 50 kt/a slurry bed residue hydrotreating unit. According to the information of both flowing phases, like apparent velocity, flow direction and volume fraction distribution, the forced recycling reactor and outer loop reactor are considered preliminary as the most suitable reactors for residue thermal cracking in presence of hydrogen.
