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 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 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 Fischer–tropsch Synthesis Packed Bed Reactor for Producing Liquid Fuels from Natural Gas
A tubular pilot scale fixed-bed reactor for the Fischer–Tropsch Synthesis (FTS) was simulated to numerically demonstrate the conversion of synthesis gas (CO+H2) to higher hydrocarbons over an iron based catalyst. The reactor was a 3.1 cm diameter and 2.75 m length steel tube. The feed temperature were between 563583 K. Saturated water was employed to control the peak temperature within the cata...
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...
