Experimental test in a lab-scale fluidized bed reactor to investigate agglomeration behavior under real conditions
This paper presents first results of experimental test runs in a lab-scale fluidized bed reactor at TU Wien to predict the agglomeration temperature of exhausted olive pomace. The controlled fluidized bed agglomeration test indicates an agglomeration temperature of approximate 945 °C by the occurrence of a pressure drop in the fluidized bed. The agglomeration phenomena is explained by the mechanism of initial low melting layer formation around burning char particles. The goal is to establish a standard prediction method based on other performed tests in similar lab-scale reactors.29
Photonic Crystals With Anomalous Dispersion: Unconventional Propagating Modes In The Photonic Band Gap
We present an investigation of the optical properties of photonic crystals whose constituent materials exhibit anomalous dispersive behavior. In particular, the anomalous dispersion near resonances may lead to additional propagating modes in the gap of the undoped system for a localized region of wave-vector space. Such a system may be realized by infiltrating quantum dots in polymer suspensions into the pores of two-dimensional high-index photonic crystals. An evaluation of the absorption lengths associated with these unconventional modes and corresponding transmission calculations demonstrate that this effect can be observed in currently accessible structures. © 2008 The American Physical Society
