Abstract:

In this study, pyrite was produced by hydrothermal precipitation from the reaction between FeSO4 and Na2S2O3 at high pressure and high temperature in a stirred reactor. The solid product was purified by means of solvent extraction to remove sulfur. Powder was characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and thermal analyses. Results indicated that pyrite was produced as nanostructure with high purity.

Coagulation in a Continuously Stirred Tank Reactor

Smoluchowski 's coagulation equation with coagulation rates K 0 oc (ij) ~ describing the temporal evaluation of the size distribution ck (concentration of k-mers) is studied in the presence of a source term ark, and a sink term --bCk. With a' a/b 2 one finds that a steady state is reached, exhibiting gelation when w > 1⁄2 and a ' > ao(w), where a0(o~) depends on w (ao(w) = ~ for ~o < 1⁄2, ao(1)...

Estimation of pyrolysis product of LDPE degradation using different process parameters in a stirred reactor

Pyrolysis of low density polyethylene (LDPE) by equilibrium fluid catalytic cracking (FCC) was studied in a stirred reactor under different process parameters. In this work, the effect of process parameters such as degradation temperature (420-510°C), catalyst/polymer ratio (0-60%), carrier gas type (H2, N2, ethylene, propylene, Ar and He), residence time and agitator speed (0-300 rpm) on the c...

CFD Modeling of Gas-Liquid Hydrodynamics in a Stirred Tank Reactor

Multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. These reactors have been studied based on Computational Fluid Dynamics (CFD) that can be used in the analysis, design and scale up of these reactors. Most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigat...

Cfd Modelling of a Novel Stirred Reactor for the Bio- Production of Hydrogen

In this work the Computational Fluid Dynamics simulation of a stirred bioreactor purposely designed for the production of hydrogen from organic wastes fermentation is presented. The bioreactor is a vortex-ingesting, dual impeller, mechanically-agitated vessel equipped with a central draft tube. Due to the geometrical and physical complexity, the selected reactor offers a very challenging benchm...

Simulation Analyses of Continuous Stirred Tank Reactor

This paper presents simulation experiments on the continuous stirred tank reactor (CSTR) which is widely used equipment mainly in the chemical industry. The behaviour of these types of systems is usually nonlinear with other negative properties such as a time-delay or a non-minimum phase behaviour and simulation could help us with the understanding of them without making real experiments which ...
