ADVANCED HIGH-PRESSURE BENCH-SCALE REACTOR FOR TESTING WITH HOT CORROSIVE-GASES

A bench-scale, high-pressure/high-temperature fluidized-bed reactor (H PTR) system is described that is capable of operating at a maximum tem perature and pressure of 1000-degrees-C and 30 bar in a corrosive atmo sphere. The design of the unit is based on a double-shell balanced-pre ssure system. All the hot parts of the reactor that are wetted by the corrosive (and/or reactive) gases and the entire sampling line are con structed of inert material to prevent corrosion and loss of the reacta nt gases. The unit has been used for over 200 high-pressure hot coal g as desulfurization tests at 20 bars and up to 750-degrees-C without an y experimental problem and with excellent sulfur balance, indicating t hat this reactor system is ideal for testing with reactive and corrosi ve gases at elevated pressures and temperature&
