Solar vacuum drop-tube reactor extensively characterized at 1, 100 and 960 mbar. Zinc production is higher at 100 mbar compared to ambient pressure. Reactor model featuring radiative heat transfer with Monte Carlo ray tracing. Reaction at 1 mbar is inhibited due to insufficient particle residence time. Maximum zinc production predicted to be 52 mmol·min−1, at a feed rate of 68 g·min−1.
