Effects of calcination and activation temperature on dry reforming catalysts

الملخص EN

The effect of calcination temperatures on dry reforming catalysts supported on high surface area alumina Ni / c-Al2O3 (SA-6175) was studied experimentally.

In this study, the prepared catalyst was tested in a micro tubular reactor using temperature ranges of 500, 600, 700 and 800-C at atmospheric pressure, using a total flow rate of 33 ml / min consisting of 3 ml/min of N2, 15 ml / min of CO2 and 15 ml / min of CH4.

The calcination was carried out in the range of 500-00-C.

The catalyst is activated inside the reactor at 500-800-C using hydrogen gas.

It was observed that calcinationenhances catalyst activity which increases as calcination and reaction temperatures were increased.

The highest conversion was obtained at 800-C reaction temperature by using catalyst calcined at 900-C and activation at 700-C.

The catalyst characterization conducted supported the observed experimental results.
