Conversion and Residence Time Calculation for Gas-solid Solid Reactions of the Cylindrical-shaped Particles with Con-stant Size Using the Shrinking Core Model
In this paper, a mathematical model is developed to calculate the conversion and the residence time reaction for plug flow and mixed flow in the reactors filled with cylin-drical particles using the shrinking core model. In this modeling, the size of the particles is un-chamged during the reaction. Also, the reaction rate is controlled by the gas layer resistance, the ash layer resistance, and ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولGas-Solid Catalytic Reactions
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...
متن کاملGas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber
One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...
متن کاملMicroreactors for Gas Liquid Solid reactions – Novel Catalyst Support Based on Carbon Nanofibers
Introduction Currently, there is tremendous interest in the field of micro-structured gas-liquid contactors containing modified catalytic coatings on its micro-structured internals (Fig. 1) [1]. The most recent trend in the design of three-phase catalytic microreactors focuses on the use of structured catalyst supports, i.e. that the catalyst has to be deposited on a rigid, orderly arranged sup...
