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...
We performed the biotransformation of ferulic acid to vanillin using Bacillus subtilis (B. subtilis) in the stirring packed-bed reactors filled with carbon fiber textiles (CFT). Scanning electron microscope (SEM), HPLC, qRT-PCR and ATP assay indicated that vanillin biotransformation is tightly related to cell growth, cellar activity and the extent of biofilm formation. The biotransformation was...
In this paper, it is presented a review about applications of biofilms in the degradation of contaminants in industrial effluents. Biofilms are typically comprised of water, microorganisms, extracellular polymeric substances (EPS), retained particles and dissolved and adsorbed substances. Water is the most significant fraction of the total mass of the biofilm, and it can vary from 70 to 95%. Po...
In this study, a mathematical model is proposed which incorporates mass transfer process and biofilm reactions in trickle bed air biofilter (TBAB). The model consists of a set of mass balance equations for isopropyl alcohol (IPA), acetone (ACE) and oxygen within the bulk gas phase and within the biofilm. These set of ordinary differential equations are converted into non-dimensionalised form an...
