Microreaction Technology (microreaction + technology)
Selected AbstractsIntegration of Microreaction Technology into the CurriculumCHEMICAL ENGINEERING & TECHNOLOGY (CET), Issue 3 2005R. Gorges Abstract As a pioneer in Germany, the Institute of Technical Chemistry and Environmental Chemistry at the Friedrich Schiller University in Jena has integrated microreaction technology into its curriculum of industrial chemistry. This essay describes how traditional lab classes in industrial chemistry are replaced or supplemented by microreaction components. It is shown how lab classes on heat transfer, heterogeneous catalysis, mixing and stirring, and photochemistry were modified to meet this objective. In addition to the practical training in different lab classes, microreaction technology was also implemented in lectures, and thus the knowledge about the various possibilities and advantages of this new technology is instilled in future generations of chemists at an early stage of their education.

Kirschneck Abstract Microreaction technology offers new opportunities, especially for the production of fine and other speciality chemicals. The area of process design, however, has not been widely reported in literature. Therefore, the aim of the current paper is to give an insight into the necessary steps of industrial process design in microchemical engineering. [source] Microreactor Array Assembly, Designed for Diversity Oriented Synthesis Using a Multiple Core Structure Library on Solid SupportMOLECULAR INFORMATICS, Issue 11 2006Alexander Groß Abstract The application of spatially encoded principles in solid phase combinatorial synthesis requires no chemical or physical coding strategies. The resulting products are encoded by their position inside the array and their synthesis history. The advantages of microreactor arrays for solid phase synthesis as one of the embodiments in the field of microreaction technology are discussed. Here, we review the reactor design, necessary process steps, and a strategy for the diversity oriented array synthesis. In particular, the glass-made microreactor and its assembly for 1563 parallel solid phase reactions, which can be performed at temperatures up to 120,°C, are described. Bead loading and liquid handling steps were adapted to this array. The production of large libraries demands suitable synthesis protocols and building blocks. The optimization of appropriate synthesis conditions is a time-consuming process. A multiple core structure library approach for the efficient synthesis of diverse heterocyclic libraries is described. The aim of this work was to prove the feasibility of the glass-microreaction array for massive parallel library synthesis. [source] An Investigation into the Transient Behavior of a Microreactor System for Reforming of Diesel Fuel in the kW RangeCHEMICAL ENGINEERING & TECHNOLOGY (CET), Issue 11 2009M. O'Connell Abstract A diesel reformer based on microreaction technology was developed for application in an auxiliary power unit (APU) system. The transient characteristics of this reactor for reforming of diesel fuel are reported. Diesel steam reforming was performed at various S/C ratios with load changes ranging from 30 % LL to 80 % LL, i.e., a 1.5 kW to a 4 kW electrical equivalent. The reactor itself was based on an integrated reformer/burner heat exchange reactor concept. The reforming was performed at temperatures above 750,°C and at various S/C ratios, down to a minimum of 3.17. Variation of experimental parameters, such as O/C and S/C ratios, are critical for optimum and efficient operation of the reformer. [source] Experimental Investigation and Modeling Approach of the Phenylacetonitrile Alkylation Process in a MicroreactorCHEMICAL ENGINEERING & TECHNOLOGY (CET), Issue 6 2009E. S. Borovinskaya Abstract The application of microreaction technology has the potential to intensify chemical processes. It is therefore of great interest to investigate the operating efficiency of a multiphase process such as the alkylation of phenylacetonitrile in a microreactor and to compare the performance to a batch reactor. The undeniable advantages of continuous microreactor systems for this process were demonstrated. Furthermore, the influence of the organic to aqueous phase ratio in the microreactor was investigated. A model of the reaction course was formulated based on experimental data. This model was used in the analysis and modeling of the alkylation process in a microreactor and found to be adequate. The optimal microreactor performance conditions were determined using the numerical optimization technique (Harrington's desirability function) and confirmed by experiments.
