KR20110106856A - Slurry bubble column reactor - Google .

A slurry bubble column reactor (11) equipped with a gas distribution device comprising one upper sparger (12), one lower sparger (13), and one tube (14) having an open end. The gas supplied from the lower sparger 13 enters the tube 14 and lowers the density of the slurry in the tube 14. The difference in slurry density causes the slurry in the tube 14 to rise and the slurry outside the tube 14 .
