“…Thus, we can state that many scientists point to a potential danger of polymer materials and nanotechnology products for the environment and human health. In addition, modern science focuses on such issues as: a life cycle of goods made of mentioned materials [34,35], methods for evaluation of a quality of nanostructures [36], disposal of polymers [3,7] and nanomaterials [37].…”

“…At the same time, harmful emissions into the atmosphere [1] and formation of waste with the subsequent accumulation of heavy metals in the ground [2] accompany each technological process. Despite the availability of modern technologies for solid waste management [3][4][5][6][7][8], which makes it possible to obtain energy raw materials [9,10], the most frequent treatment is burial. This fact contributes to:…”

“…The modelling of coal de-volatilization, combustion and gasification in the form comprehensive model and CFD (computational fluid dynamic) code are already performed in Waste to Energy Lab at Masdar Institute, Abu Dhabi with variety of different feedstock [3][4][5][6][7][8][9]. The similar modelling techniques that are used for coal or biomass cannot be used directly for char due to the large difference in the physical and chemical properties.…”

A first principal modeling of the gasification of a char particle is performed using single step mechanism. The char particle is considered to be spherical in shape and only the physical and chemical properties can change in the radial direction. The carbon dioxide is used as the gasification agent that reacts with the char and form carbon monoxide. The presence of both solid and gaseous phase species makes the reaction heterogeneous. The char particle is considered with varying porosity that also allows the change in the surface area of the particle. A time invariant temperature and pressure profile is used at which the Arrhenius rate constant and diffusion is calculated. The mass conservation of model results in the form of two coupled partial differential and one ordinary differential equation. The equations are solved with a set of initial and boundary conditions using the bulk species concentration at the particle surface. A second order accurate central differencing scheme is used to discretize space while backward differencing is used to discretize time. Finally, the results are presented for the concentration distribution of CO and CO 2 in radial direction with respect to time. It shows that, maximum concentration of CO is present at the center of the particle while the concentration gradient becomes higher near the particle surface. The nonlinear concentration trend due to the diffusion is effectively captured. The results show that, completed conversion of char depend upon the time provided for the reaction which can be reduced by decreasing the size of particle or increasing the reaction temperature. The sensitivity study of temperature and initial porosity also performed and showed that temperature has high impact on char conversion as compare to initial porosity.
