An improved micro-reactor cell for IR spectroscopic studies of heterogeneous catalysis was built around a 5.8 GHz microwave cavity. The reactor can operate at 20 bars and with conventional heating up to 720 K, with reactant gas flows velocities (GHSV) from 25,000 to 50,000 h(-1). The temperature of the sample under microwave irradiation was measured by time resolved IR emission spectroscopy. The first experiment performed was the IR monitoring of the desorption of carbonates induced by irradiating an alumina sample by microwaves at 5.8 GHz.
一种用于多相催化红外光谱研究的改进型微反应器池围绕一个5.8 GHz微波腔构建。该反应器可在20巴的压力下运行，采用传统加热方式时最高可达720 K，反应气体流速（气体时空速）为25,000至50,000 h⁻¹。通过时间分辨红外发射光谱法测量微波辐照下样品的温度。进行的第一个实验是对在5.8 GHz微波辐照氧化铝样品时诱导的碳酸盐脱附进行红外监测。
