The outline of this chapter is as follows: *.1 will show some application areas together with the number of types of reactors available for carrying out gas-solid catalyzed reactions. Section *.2 will focus on the kinetic models suitable for describing these reactions. Section *.3 will show how to set up the reactor models and will also show the mass transport interactions need to be modeled. T...
Heterogeneous gas-solid reactions play an important role in a wide variety of engineering problems. Accurate numerical modeling is essential in order to correctly interpret experimental measurements, leading to developing a better understanding and design of industrial scale processes. The exothermic nature of gas-solid reactions results in large concentration and temperature gradients, leading...
This paper gives an overview about the principles and the technologies used in solid-state gas sensors. These devices work by measuring a physical property changed by adsorption/desorption processes and chemical reactions on the surface of a sensing element, i.e. a solid-state film of a gas-sensitive material. Some of the most used types of solid state gas sensors are here described together wi...
The direct link between microstructure and material properties is the core principle underpinning modern material science and engineering. Phase transformations in solids and solidification of melts have been extensively studied to the point where the key elementary processes, process steps and process variables are well understood. Less well investigated and less well understood are the change...
