Abstract
One of the new technologies used in the process of converting natural gas into liquid fuel is GTL (compact reactor). This reactor has many advantages compared to the reactors used, which can be considered due to the small diameter of the reactor, temperature runaway does not occur in it. and the reactor used in the laboratory scale is scale up in a compact manner and for high capacities it is used in a modular approach. The catalyst used in the compact reactor must be have more activity than conventional catalysts. In this research, the kinetics of the above-mentioned catalyst was obtained by conducting experimental design. Catalyst size, the diameter of the single-tube reactor was obtained. Finally, considering the hydrodynamic design considerations, the 19-tube compact reactor was designed to produce 6 liters per day. After examining different cases, the design of the 19-tube reactor was selected, taking into account all considerations, with a triangular arrangement in a cylindrical module with a diameter of 50 mm.
