Abstract
An internal loop airlift reactor (ILAR) for process intensification integrating reaction and separation includes a riser, a downcomer, a hydrocyclone, internals preventing occurrence of dead zone, a gas guide cone, vent holes, and a gas-liquid integrated distributor. The hydrocyclone is arranged at the bottom of the ILAR downcomer; the gas guide cone and the vent holes in the downcomer prevent the gas from entering the hydrocyclone; after the slurry enters the hydrocyclone, the solid-containing slurry enters the riser again from the hydrocyclone underflow, and the solid-free clean product flows out through the hydrocyclone overflow. The ILAR in the present invention has a simple structure and low cost and requires no special liquid-solid separation device. It can achieve gas-liquid-solid three-phase reaction, interphase mass transfer, and solid-liquid separation simultaneously, and is suitable for a gas-liquid-solid three-phase reaction in which the catalyst is solid particles.
