The produced gases are then separated on a chromatographic column and detected by a Thermal Conductivity Detector (TCD). Oxygen is determined by pyrolysis. Samples are weighed in silver containers and introduced into the reactor containing nickel-coated carbon. Oxygen is determined as carbon monoxide. After separation from other products it is detected by TCD. The equipment is associated with a high-precision micro-metric balance (Mettler Toledo) for sample preparation. The analyzer configuration includes:

  • Flowrence 1221: Propylene, alcohol and glycerol oxidation and glycerol or hexose valorisation.

Flowrence contains 4 temperature blocks, each one can be operated at different temperature. Each block can receive 4 stainless steel or quartz reactors, so 16 isothermal fixed bed micro flow reactors can run in parallel and 16 experiments can be conducted simultaneously. Between 50-500 mg of catalyst can be loaded in one reactor. Flowrence can operate at wide conditions range: pressure between atmospheric and 90 bars, temperature between 50°C and 750°C, feed can be either gas, liquid or trickle flow.
