Katalysatoruntersuchungen an einer Technikumsanlage für Biomasse‐Kleinfeuerungen

In addition to the reduction of particulate matter, a catalytic supported emission reduction in small scale biomass combustion systems can also enable a conversion of toxic organic components into carbon dioxide and water. For catalyst investigations under practical conditions a special test facility was designed. The results show that products of incomplete combustion like carbon monoxide from stoves can be reduced by catalytic processes. Further developments and studies are necessary to achieve the targeted emission limits.     

CFD in der chemischen Verfahrenstechnik aus industrieller Sicht

Computational fluid dynamics (CFD) is increasingly becoming established as a tool for analysis and design in the chemical industry. Several projects from various areas are introduced as examples of CFD projects from the perspective of the CFD user in chemical industry. The areas chosen are based on those in a process chain: transportation, mixing, reaction, and separation of materials. The most important steps and decisions in the use of CFD are presented from the perspective of the process engineer. This paper attempts to convey an appreciation for the possibilities and opportunities, but also for the limits of computational fluid dynamics.
