Mechanisms of Gas Ejection in Bubble Column for Fischer-Tropsch Synthesis with Suspended Nanocatalysts

摘要

The gas-liquid ejector functioning mechanisms that may be involved in three-phase Fischer-Tropsch suspension synthesis using nano-scale catalyst particles are studied for the first time. It is shown for a model bubble device representing a pilot reactor of the referred synthesis process that it is possible for the ejector to perform simultaneously the functions of both the gas disperser of the column and of the device that ensures forced circulation of the liquid medium in the whole device loop. Supersonic gas ejection condition is achieved and its effect on the bubbling pattern is determined.
