New algorithm for random selection of the next neighbour site in a self-avoiding random walk and efficient mechanisms of mobility of components are introduced to improve the universality of the predictions by removing commonly occurring simulation deficiencies due to early trapping of radicals. The model has the capability of predicting the onset of the sol-gel transition and the effect of chemical composition on the transition point. It is shown that there is attained a better understanding of microstructure evolution and appearance of gel phase during polymerization and chemical gelation. Finally, one important benefit of the simulation method is the ability of characterizing system in which, the dominant combination reaction leads to highly branched structure.

To determine the optimum condition of decolorization, the influential parameters including initial dye concentration, catalyst quantity, hydrogen peroxide concentration, pH value and UV light intensity were evaluated using the Taguchi statistical method. The results indicated that compared to the other parameters, UV light intensity was the most effective. The theoretically predicted value of decolorization efficiency (95.48%) was confirmed by the experimental value (95.22%). The mineralization was considered significant with regard to the obtained values of total organic carbon (TOC) analysis (92.52%) and chemical oxygen demand (COD) analysis (94.05%) in the optimum condition. Investigations were also carried out to determine the appropriate adsorption isotherm and kinetic model in the optimum condition. The obtained optimum condition for dye removal was finally examined applying a real sample of textile wastewater containing the dye.

The adsorption of aromatics (benzene and toluene) from hexane, heptanes and octane was measured at room temperature. Already at low concentrations, the aromatics were selectively adsorbed on NaY from their binary mixture with an alkane. In NaY zeolite, benzene and toluene are preferentially adsorbed over C6, C7 and C8 n-alkanes (benzene/n-C6 and toluene/C6 selectivity as high as 1000), because benzene and toluene have a higher heat of adsorption and pack more efficiently in the NaY super cages. Results for aromatics are consistent with specific interaction of its π π π π π electrons with Na atoms on the zeolite surface. These interactions increase the heat of adsorption for aromatics with NaY zeolite. Also, the interaction of n-alkanes with active sites on the surface indicates the heat of adsorption is lower than that for aromatics.

Titanium (IV) oxide was supported on clinoptilolite (CP) (Iranian natural zeolite) using solid-state dispersion (SSD) method. The results show that the TiO 2 /clinoptilolite (SSD) are an active photocatalyst. The maximum effect of photodegradation was observed at 10 wt.% TiO 2 , 90 wt% clinoptilolite. A first order reaction with K = 0.0127 min !1 was observed for the photocatalytic degradation reaction. The effects of some parameters such as pH, amount of photocatalyst, and initial concentration of dye were also examined. Based on the results, a model was proposed for photodegradation of dyes using immobilized [TiO 2 /clinoptilolite (SSD)]. This model can be useful for the development of this technology for wastewater treatment applications.

The photocatalysts were synthesized by coating of ZnO onto the magnetite by precipitation method and characterized by XRD, SEM and FTIR measurements. Using the Taguchi method, this study analyzes the effect of parameters such as calcinations time, calcinations temperature and molar ratio of Fe3O4:ZnO on the photo activity of Fe3O4/ZnO MNPs. XRD and FTIR analysis confirm that coating process was done successfully. SEM images show that the average particle size of synthesized Fe3O4/ZnO nanoparticles was about 50 nm. The phenol removal efficiency of 88% can be achieved by using a photocatalyst which is synthesized through the optimum conditions: calcinations temperature of 550°C, calcinations time of 2 hours and molar ratio of 1:10 for Fe3O4:ZnO.

Three methods of heat-release estimation (HRE), namely, kinetic model (KM), online energy balance (OLEB) and calorimetric-state estimator (CSE) were investigated. The following three criteria were used to assess these methods: (i) Ability to adjust kinetic errors. (ii) Ability to adjust against dynamic errors. (iii) Sensitivity to temperature noises. The results indicate that the CSE method has a better performance with respect to kinetic and dynamic errors. Additionally, by using this method, the temperature control design becomes self-tuning

The experiments were carried out in a laboratory-scale plug flow reactor over the temperature range of 560-600˚C at atmospheric pressure. Several Langmuir-Hinshelwood mechanisms for C3 and iC4 were tested. Models were derived with the assumption of propane, isobutane and hydrogen adsorption on the same type of active site. A simple deactivation model was used for fitting the kinetic data, then the best fit for these reactions was found with the rate determining step (RDS) of surface reaction for propane and adsorption on the catalyst surface for isobutane. The results showed a good agreement between experimental and calculated data for these simultaneous reactions.

In this investigation, the fractal dimension was determined by a procedure known as the “Box Counting Method”. Using this dimension, surface area relations were developed for the rough particles. This method was implemented in the PEM (Petite Ensemble Model) burning rate model. The comparison of burning rates for a typical propellant by the PEM and fractal model shows that the burning rates obtained by using the fractal geometry are slightly less than those obtained by the PEM model.
