The performance of both fluidized and spouted bed reactors in the pyrolysis waste plastics is conditioned by particle agglomeration phenomena, which worsens quality gas–solid contact eventually lead to defluidization. objective this work determine optimum conditions for stable operation (without defluidization) a bench scale plant fitted with fountain confined conical reactor equipped nonporous...

effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated.  experiments were carried out in the range of 25-600 ºc and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. time-position trajectory of particles was obtained by radioactive particle tracking technique. these data were used for determination of mean velocities of...

in this study two identical anaerobic completely mixed fluidized bed reactors with gac and sand media were employed for cod & phenol removal. at loading rate of 1.6 g phenol l-1d-1, the efficiency of phenol removal in gac & sand reactors were 97.7% & 74%, respectively. at high loading rate of phenol (6.09 g phenol i: 1d1) the efficiency of phenol removal in gac reactor was better than 95%. in g...

In this study, the fluidized bed reactor was used to carbonize corncob in the carbonization step of producing carbon adsorbent with large specific surface area. The experiment showed that not only the efficiency of carbonization, but also the value of specific surface area and specific pore volume of the produced carbon were obviously increased. The experimental operating conditions were as fol...

The control of fluidized-bed operations processes is still one of the major areas of research due to the complexity of the process and the inherent nonlinearity and varying dynamics involved in its operation. There are varieties of problems in chemical engineering that can be formulated as NonLinear Programming (NLPs). The quality of the developed solution significantly affects the performance ...
