Evaluation of catalyst activity for methanol synthesis wascarried out over a pressurized micro-reactor system. The systempressure was controlled at 4MPa using a Brooks 5866pressure controller (PC). A gas mixture of CO2/H2 (1/3)was used as feedstock and the flow rate was controlled by aBrooks 5850 mass flow controller (MFC). The reaction temperaturesstudied were in the range 493–533K and the spacevelocity was ca. 100,000 h.1. The products were analyzedusing an on-line HP5890 gas chromatograph (GC) equippedwith a thermal conductivity detector (TCD) and a PorapakQS column (3 m), which was temperature programmed from353 to 393 K.

Around 0.25 g of wet catalyst was loaded into the reactor;this was then placed in the constant temperature zone of theair oven. Pure hydrogen was passed at ambient pressure andtemperature for 0.5 h before the temperature was increasedto 423 K. The reactor was then slowly heated (3 K/min) to513 K, held there for 4 h, and then the temperature was decreasedto 473 K. The feedstock was then admitted into thereactor. The pressure was raised to 4.0MPa and the temperaturewas adjusted to the desired value. On-line GC measurementswere started after the system reached steady operationstate.

Activities of the catalysts for the WGS and MSR werealso carried out using a conventional micro-reactor flow system.Liquid feedstock was pumped to a stainless steel reactor(6.35mm o.d., 100mm length) using an ISCO LC-2600pump attached to an evaporator. Gas flow rates were controlledusing Brooks 5850 mass flow controllers. Productswere analyzed using the on-line gas chromatograph fittedwith a TCD after separation using a Porapak Q column1.8 m) at 393 K.
