The performance of a fixed-bed and entrained flow reactor for the sorption-enhanced methanol synthesis from CO2 is assessed by modelling. Both reactors achieve good but show possible drawbacks. fixed bed requires several units working in parallel, while needs large volume due to high superficial particle velocity. We propose new type, which combines circulating sorbent with fluidized catalyst b...

A packed-bed membrane reactor in a distributor configuration is studied theoretically for the oxidative propane dehydrogenation and compared with fixed-bed reactor. Based on detailed 2D models considering two different heat mass transport scale-up including various reactor-to-particle diameter ratios (D/dP) analyzed respect to performance, transfer hot spot formation. Higher selectivities at lo...

Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...

Studies on bench scale reactors packed with two different media matrix – Biopac media and Fugino spirals were undertaken to determine the performance at various organic loading rate (OLR) and on one day hydraulic retention time (HRT). Parboiled rice mill wastewater depicted a COD/BOD ratio of 1.6 indicating good degradable nature of the wastewater. Four different organic loadings of 0.8, 1.6, 2...

The development of tools for the synthesis, design, and optimization biorefineries requires deep knowledge thermochemical processes involved in these schemes. For this project, three models from scientific literature were implemented to simulate processes: fast pyrolysis a fluidized bed, fixed-bed, fluidized-bed gasification using Aspen PlusTM software. These allow user obtain performance, cons...

In this research, Fischer Tropsch synthesis (FTS) has been modeled in the fixed bed chromatographic reactor for the first time by applying a rather complex dispersed plug flow model for fluid phase and linear driving force (LDF) model for adsorbent. Model equations are dynamic, multi-component, non-linear and heterogeneous including reaction and adsorption simultaneously Complex kinetics fo...
