Abstract
Catalyst particle distribution and mixing in slurry part of bubble columns is improved by introducing a secondary suspending fluid into the columns at locations within the lower 20% of the vertical height of the column but above the gas distributor normally located at or near the bottom of the columns.
Claims5
A method for improving the axial distribution of catalyst in a hydrocarbon synthesis slurry bubble column which uses rising synthesis gas introduced by means of synthesis gas distribution means located at the bottom of said column to provide the majority of the energy used in distributing catalyst in said column, the improvement in axial distribution of catalyst being achieved by using a secondary fluid introduction means in said slurry bubble column at a location above the synthesis gas distribution means located at the bottom of said column to introduce a secondary fluid stream into said column.
