Bubbles – catalysts – oil interactions at elevated temperature and pressure in Fischer Tropsch synthesis

摘要

Driving force for this research is dictated by the fact that resources of crude oil, key source of energy in our Everyday life, are limited. Therefore the extensive work is currently carried out to find alternatives such as fully Synthetic fuels - Fisher Tropsch synthesis (FTS). Though FTS was developed in 1923 until recently it was Nearly forgotten. Recent prices of crude oil make this technology attractive again and new research aimed at Optimisation is necessary. The aim of this work was to investigate the behavior of different catalyst in gas/oil dispersion and the effect on Overall mass transfer rate. Efficiency of the entire synthesis, specifically, what is the effect of steam at those Conditions was investigated, since there is practically no information in open literature. This work shows summary of the similarities and differences of properties of all the investigated catalyst and Evaluation of their performance. It was shown that the interactions and ultimately the effect that particles have On the bubble size made of either polar or non-polar gas depends on the particles lyophobicity.
