CFD modeling of slurry bubble column reactor for Fischer-Tropsch synthesis
Industrial bubble column reactor for Fischer-Tropsch (FT) synthesis includes complex hydrodynamic, chemical and thermal interaction of three material phases: population of bubbles of different sizes, liquid and catalyst particles suspended in liquid. To simulate FT bubble column, a Computational Fluid Dynamics model is described here. The model is based on Eulerian multifluid formulation and ac...
متن کاملModeling the Fischer-Tropsch Reaction In a Slurry Bubble Column Reactor
Fischer-Tropsch synthesis is one of the most important catalytic reactions that convert the synthetic gas to light and heavy hydrocarbons. One of the main issues is selecting the type of reactor. The slurry bubble reactor is suitable choice for FischerTropsch synthesis because of its good qualification to transfer heat and mass, high durability of catalyst, low cost maintenance and repair. The ...
متن کاملModeling of the Fischer–Tropsch synthesis in slurry bubble column reactors
A multicomponent one-dimensional dynamic mathematical model for the reacting slurry systems with a change in gas flow rate due to the chemical reaction is developed. A change in gas flow rate caused by the chemical reaction is modeled using the overall gas mass balance. Thus, all relevant chemical species are included in the model. Linear first-order reaction kinetics is considered. The gas pha...
متن کاملA Study of Gas Flow in a Slurry Bubble Column Reactor for the DME Direct Synthesis: Mathematical Modeling from Homogeneity vs. Heterogeneity Point of View
In the present study, a heterogeneous and homogeneous gas flow dispersion model for simulation and optimization of a large-scale catalytic slurry reactor for the direct synthesis of dimethyl ether (DME) from synthesis gas (syngas) and CO2, using a churn-turbulent regime was developed. In the heterogeneous flow model, the gas phase was distributed into two bubble phases including small and large...
متن کاملDetermination of the Product Selectivity Model from the Fischer Tropsch Synthesis in a Fixed Bed Reactor
The Fischer-Tropsch synthesis is a catalytic process that can produce a fuel similar to fossil fuels by using primary sources such as agricultural waste and carbon sources that can convert into synthesis gas by superheated steam. All fuel derivatives can be supplied through the Fischer-Tropsch reaction. The synthesis produces a variety of hydrocarbons via parallel and sequential reactions. Howe...
