Hydrocracking has great importance in present day refining due to strict environmental and norms of quality of fuel. In recent years the demand for middle distillate and gasoline has increased tremendously while that of heavy gas has decreased. In the present work we have modeled and then applied five lump scheme to hydrocracker reactor. The first order kinetics was assumed for the conversion i...

The potential for efficient production of hydrogen-rich gas from hydrocarbon fuels using thermal plasmas has been investigated both analytically and experimentally. Thermodynamic analysis shows that the most efficient production of hydrogen from hydrocarbons can be achieved by partial oxidation (lambda = 0.25); at optimal conditions, the availability of the output fuel mixture is 83 percent of ...

In the last decade, Microreactor Technology (MRT) as a new concept in chemical engineering has demonstrated the advantages of microstructured devices for chemical reactions impressively. Microscale reactors are devices whose operations depend on precisely controlled design features with characteristic dimensions from submillimeter to submicrometer. Due to the small amount of chemicals needed an...

The aim of this work is to solve an identification problem in plug-flow chemical reactors. This leads to an optimization problem involving parameters and for which the adjoint method is introduced for calculating the gradient of the objective function. An adjoint-based algorithm for parameter identification problems in systems of partial differential equations is presented. The algorithm calcul...

To enhance the treatment efficiency from an anaerobic digester, a novel six-compartment anaerobic/oxic baffled reactor (A/OBR) was employed. Two kinds of split-feeding A/OBRs R2 and R3, with influent fed in the 1st, 3rd and 5th compartment of the reactor simultaneously at the respective ratios of 6:3:1 and 6:2:2, were compared with the regular-feeding reactor R1 when all influent was fed in the...

I solved equations that describe coupled hydrolysis in and absorption from a continuously stirred tank reactor (CSTR), a plug flow reactor (PFR), and a batch reactor (BR) for the rate of ingestion and/or the throughput time that maximizes the rate of absorption (=gross rate of gain from digestion). Predictions are that foods requiring a single hydrolytic step (e.g., disaccharides) yield ingesti...

This work investigates the non-catalyzed supercritical methanol (SCM) process for continuous biodiesel production. The lab-scale setup was designed and used production in temperature range of 520–650 K 83–380 bar with an oil-to-methanol molar ratio ranging from 1:5 to 1:45. experiments were performed coiled plug flow tubular reactor. volumetric rate methanol/oil ranged 0.1–10 mL/min. examines a...

This study reports the analysis and design of a liquid phase esterification process to convert acetic acid with isoamyl alcohol into acetate via reactive pervaporation, in presence an Amberlite IR-120 ion exchange resin catalyst. To accomplish this, catalytic reactor is coupled separation membrane unit (Pervaporation Membrane Reactor (PVMR)). In proposed unit, chemical reaction equilibrium favo...

Over the last years a new type of tubular plug flow reactor, the segmented flow tubular reactor (SFTR), has proven its versatility and robustness through the water-based synthesis of precipitates as varied as CaCO3, BaTiO3, Mn(1-x)NixC2O4·2H2O, YBa oxalates, copper oxalate, ZnS, ZnO, iron oxides, and TiO2 produced with a high powder quality (phase composition, particle size, and shape) and high...
