Development of multi-functional catalysts for the direct synthesis of valuable hydrocarbons from synthesis gas 

In this project, multi-functional catalysts will be synthesized for the direct production of liquid fuels from syngas in Fischer-Tropsch Synthesis(FTS) reaction.

Since products from conversional FTS catalysts always follow Anderson-Schulz-Flory (ASF) distribution, it is theoretically impossible to selectively produce only hydrocarbons in the gasoline ranges. Meanwhile, mostly due to hydrogenolysis and direct CO hydrogenation,  current zeolite-supported FTS catalysts produce an undesired amount of methane. Therefore, further work is necessary to tune the active metal component and to enhance diffusion thorugh the zeolitic support. 

Further research will be focused on developing new catalyst preparation methods and hierarchical zeolites with more accesible mesopore surface area and volume. Then FTS reaction will be investigated on zeolite-supported catalysts.
