The results show that heat removal and heat transfer optimization are difficult to avoid the formation of hotspots. Adjusting hydrogen fed into the two reactors and recycling the product gas show the ability to decrease peak temperatures and suppress hotspot formation. Low raw gas pressure makes it difficult to activate the reaction, and a pressure higher than 0.5 MPa is required for methanation activation. When the operation loads of feed biogas and H2, namely, the flow compared to baseline condition, range from 5% to 110%, a total conversion higher than 99% and an energy efficiency of approximately 75% are achieved.

In this study, an experimental and machine learning-based framework was developed to evaluate and optimize the performance of an air-based PVT system with different internal obstacle configurations. Experiments were conducted under real climatic conditions in Chennai, India, at two mass flow rates. Support vector regression (SVR) and decision tree (DT) models were used to predict electrical efficiency, whereas response surface methodology (RSM) optimized the operating parameters.
