Multi-region slurry shell-and-tube reactor

A multi-region slurry shell-and-tube reactor, comprising a shell, wherein at least two reaction regions are provided inside the shell, a transverse partition plate is provided between the any two adjacent reaction regions, which is configured to separate any two adjacent reaction regions and pass through tube rows, a central hole is provided at the center of each transverse partition plate, an auxiliary hole distributed around a central axis of the central hole is provided in each transverse partition plate to generate a vortex state in the at least two reaction regions cooperating with the central hole, the gas-liquid mixed reactant in the at least two reaction regions ascends through the central hole due to low density while the gaseous reactant descends through the auxiliary hole due to high density, so as to form a rising and falling circulation phenomenon in the at least two reaction regions, and block the liquid reactant from circulating along an inner chamber of the shell,

• wherein an inner diameter of the central hole ranges from ⅕ to ⅓ of an inner diameter of the shell,
• wherein an inner diameter of any auxiliary hole ranges from 1/10 to ⅛ of the inner diameter of the shell,
• wherein a first reaction region is provided at the bottom of the at least two reaction regions, the at least two reaction regions comprises the first reaction region located at a bottom end of the shell, a gaseous reactant inlet and a liquid reactant inlet are provided on a side of the first reaction region, and the liquid reactant inlet is located above ½ of a height of the first reaction region.
