WebHot spot (as shown in Fig. 8) is then formed due to the intensified C-H 2 reaction at the initial 2–5 min. Compared to the hydrogen inlet temperature (1,123 K), the temperature rise for 1 MPa is only 40 K, suggesting the CCHG reaction occurs slowly. With increasing pressure, the maximum temperature rises for 2 MPa, 3 MPa, and 4 MPa are 110 K ...
