由于一品红是一种脂肪含量较低的纤维素类植物，以往固定床热解研究的产油率较低。为了提高生物质的油产率，在固定床反应器上进行了生物质热解实验，选用了两种工业催化剂，即Critarion-534和活性氧化铝，以及天然沸石(Klinopilite)。实验在静态气氛中进行，升温速率为7°Cmin−1，热解温度为5 5 0℃，平均粒径为0.5 5 mm。在实验中，以不同的比例使用不同的催化剂，考察了不同的催化剂对所得油收率和化学组成的影响。使用天然沸石、Critarion-534和活性氧化铝的油产率分别达到27.5%、31%和28.1%，而不使用催化剂时，油产率仅为21.6%。对裂解油进行了光谱分析和色谱分析，并与无催化剂的类似实验结果进行了比较。
Since Euphorbia rigida is a celluloid plant with low fat content, the oil yields of previous fixed bed pyrolysis studies were low. In order to increase the oil yield, biomass pyrolysis experiments were performed in a fixed bed reactor with two selected commercial catalysts, namely Criterion-534 and activated alumina, and natural zeolite (klinoptilolite). Experiments were conducted in a static atmosphere with a heating rate of 7 °Cmin−1, pyrolysis temperature of 550 °C and mean particle size of 0.55 mm. In the experiments, all the catalysts were used with various percentages, and the effects of the variable catalysts on the yields and chemical composition of the oils obtained were investigated. Oil yield reached 27.5% with the use of natural zeolite, 31% with Criterion-534 and 28.1% with activated alumina, while it was only 21.6% without a catalyst. The pyrolysis oils were examined by using spectroscopic and chromatographic analysis techniques, and the obtained results were compared with the results of similar experiments achieved without a catalyst.
