Improvements in the Modeling of the Self-ignition of Tetrafluoroethylene

M. Beckmann-Kluge, F. Ferrero, V. Schröder, A. Acikalin, and J. Steinbach
Federal Institute for Materials Research and Testing, Technical University, Berlin, Germany

Tetrafluoroethylene (TFE) is a gas widely employed in industry, which can under specific circumstances experience an exothermic dimerization to octafluorocyclobutane. If the heat generated by this reaction cannot be dissipated to the surroundings, the temperature inside the reactor will ... Per saperne di più

Cluster Diameter Determination of Gas-solid Dispersed Particles in a Fluidized Bed Reactor

M. Das
Department of Biotechnology, PESIT, Bangalore, Karnataka, India

Clustering is a common hydrodynamic characteristic observed among suspended gas-solid particles in a fast fluidized bed (FFB) regime of a circulating fluidized bed (CFB) system. In this paper clustering behavior has been studied with Geldart group B particles like coal and iron ore in a ... Per saperne di più
