| 摘要 |
A multibed hydrodewaxing process and apparatus for hydrodewaxing a hydrocarbon feedstock is disclosed. A two-phase mixture of H2 and liquid hydrocarbon passes through a series of spaced catalyst beds. Reaction vapors, containing olefins, are withdrawn between beds. Preferably, the vapor liquid separation occurs intermediate two dewaxing reactor beds, with H2 added after separation, followed by liquid redistribution. Vapors, containing olefins are preferably converted into lube stocks by oligomerization. |
