Design- Development of Fischer- Tropsch Synthesis Reactor & Catalysts and their Interrelationship

The Fischer-Tropsch (F-T) Synthesis process is an unique example of catalyst and catalytic reactor interrelationship, as a dozen type of reactors have been investigated during the development of the process since 1923. From these investigations it is seen that different types of catalysts are needed for different types of F-T reactors. Relevant fundamental design aspect of various type of F-T reactors have been examined from the view point of catalyst- reactor interrelationship. Analysis have shown the role of active site and its concentration, pore size, effect of liquid hydrocarbons presence during synthesis in the pores on pore diffusion and ultimate effective utilization of total volume of catalyst and reactor. Different physical properties of catalyst have been found to be associated with different reactor configuration while dealing with heat transfer system design
