A Minipilot Solar Reactor System (MSRS) with liquid organic feed was designed, constructed and tested without solar input (the Solar Tests were to be done later at DOE's National Renewable Energy Laboratory). The non-solar tests were done to determine whether use of EPA's sampling and analysis methods would allow quantitation of the expected significantly lower organic emissions when the MSRS is operated with solar input. Results of the 10 tests showed that it should be possible to determine if there is a significant reduction in emissions (>3X) when operating with solar input. Such reduction in the emissions should be determinable for two of the principal constituents contained in the synthetic feed liquid (CC4 and DCB), for both the volatile and semivolatile products of incomplete combustion (PICs) and for dioxins and furans. But reductions are probably not determinable for the other two feed constituents (toluene and naphthalene). Results also showed that a three-fold reduction in volatile PICs occurred in both single-chamber tests when an artificial UV light was utilized.
