Fixed bed reactor experimental apparatus

Fixed bed reactor experimental apparatusDevice features

Reactor micro refillable1-3mlThe catalyst and reaction heating furnace are tubular, and the mass flow meter automatically controls and displays the gas flow rate. The liquid feeding is done by a micro level flow pump, with pressure digital display. There is computer acquisition and control software that can collect system temperature, pressure, and liquid flow data. The system operation is stable, the data is reliable, and the repeatability is good.
