| 英文摘要 | In regenerative cooling channel, predicting the time-dependent cumulative behavior of wall coking asso-ciated with endothermic hydrocarbon fuel pyrolysis is critical which is deficient now. The growth of coke is similar to the gasification of solid in the phenomenon by observing the morphology evolution. In this study, a transient coking model C-RPM, which consists of pseudo-structure function and surface reaction function two parts, was constructed on the basis of random pore model (RPM) for the initial presence of catalytic coking process. After scaling in time dimension, a good agreement with the unsteady-state cok-ing experiments of n-heptane (NC7) and methylcyclohexane (MCH) was achieved. Sensitivity analysis was performed and results showed the critical particle size dcrit and coke mass mcrit were the most impor-tant parameters affecting the coking curve. The coking space after particle fusion w(t) determines the mode of coke weight gain curve. A multi-stage periodic coking process may exist by inference. CO 2023 Elsevier Ltd. All rights reserved. |
