Abstract
The paper discusses the design and characterization of a 1200 C flow reactor for studying non-catalytic gas/solid reactions. The reactor is designed for high-temperature isothermal operation in a developing laminar-flow regime. The process gas is raised to the reaction temperature by a tubular preheat furnace fitted with sequential alumina honeycombs for increased convective and radiative surface area. The preheat furnace eliminates typical use of a flame burner to reach these high temperatures, thereby eliminating combustion gases which may affect the reaction of interest. The reactive solid is introduced into the flow reactor by a water-cooled injection probe. Reacted solids are collected by a stainless steel, water-cooled probe capable of axial movement. Solids residence times can be varied between about 50 and 250 ms, depending on process gas flowrate and collection probe height in the reactor. Sample results are presented for the CaO/SO2 reaction at varying times and temperatures.
