进行实验室实验以确定环戊烷作为有机朗肯循环工作流体的最高操作温度。在 240、300 和 350 °C、43 bar 的玻璃衬里加热管中的再循环回路中测量环戊烷的热化学分解。经测定，在两个较低温度下，在没有空气的情况下，连续运行超过12天后，分解程度较小。在 240 °C 下，环戊烷分解产物总量约为 65 ppm，在 300 °C 下，实验结束时总分解产物约为 270 ppm。在 350 °C 时，分解产物明显更高，达到 1500 ppm。当进料在主要大气条件下被空气饱和时，分解速率急剧增加。分解实验后在反应器中发现的残留物通过多种不同的技术进行了检查。残留物的质量随着实验温度的升高而增加...
Laboratory experiments were performed to determine the maximum operating temperature for cyclopentane as an organic Rankine cycle working fluid. The thermochemical decomposition of cyclopentane was measured in a recirculation loop at 240, 300, and 350 °C at 43 bar in a glass-lined heated tube. It was determined that, in the absence of air at the two lower temperatures, decomposition was minor after more than 12 days of continuous operation. At 240 °C, the total cyclopentane decomposition products were approximately 65 ppm, and at 300 °C, the total decomposition products were on the order of 270 ppm at the end of the experiment. At 350 °C, the decomposition products were significantly higher and reached 1500 ppm. When the feed was saturated with air under prevailing atmospheric conditions, the decomposition rate increased dramatically. Residues found in the reactor after the decomposition experiments were examined by a number of different techniques. The mass of the residues increased with experimental tem...
