Apparatus for subjecting liquids and No gas preferably containing hydrocarbons, to a catalytic conversion as hydrodesulfurization, hydrocracking, or the like.

摘要

The invention relates to catalytic conversion of fluid introduced into the upper end of a vessel (1), passed through a catalyst bed in the vessel (1), passed through passage (20) between guide elements (14) arranged in the vessel (1), and removed from the lower end of the vessel (1), wherein at or near narrow parts of the passages (20) cooling fluid is introduced into the passages (20) to control the temperature in the catalyst bed.
