METHOD OF CONDUCTING A CHEMICAL REACTION IN A SLURRY BUBBLE COLUMN REACTOR

摘要

A slurry bubble column reactor comprising: a slurry zone arranged to contain in use a volume of slurry comprising a liquid phase in which solid particles are suspended; a gas space above the slurry zone; gas supply apparatus 11 arranged to supply gas to the slurry zone; a gas outlet from the gas space; and a liquid outlet. The gas supply apparatus comprises a gas supply pipe 13, gas manifolds 14 tubular distribution rings 20-24 and a set of gas nozzles. The nozzles open downwards and are arranged in use to inject gas into the slurry zone of the reactor, thereby forming downwardly extending gas jets of length L in the slurry. The nozzles are distributed generally evenly across the cross section of the reactor and are arranged to direct their gas jets towards the bottom of the reactor in order to dislodge settling catalyst particles.
