The Design, Operation and Characterization of a Plasma Reactor for the Generation of Value Added Products

A reactor was designed and constructed to perform experiments on the generation of value added products using a plasma heat source. The engineering drawings were developed to include multiple sample ports for temperature and velocity measurements and view ports were designed to allow the Physics group to make optical measurements. Two methods for feeding solids into the system were developed and installed. Preliminary experiments were performed to characterize the system at various flow rates and power settings. Experiments were performed using zinc metal and oxygen to form zinc oxide. The particles that were generated were characterized chemically using atomic absorption and x-ray diffraction; and physically using scanning electron microscopy. The particles appear to be of value added size; but there is a tendency for the fine particles to adhere to one another forming agglomerates. Additional experimental work will continue the evaluation of the major parameters.
