摘要
A detailed model of a moving bed coal gasifier can provide temperature and composition profiles throughout the reactor, as well as effluent gas composition and temperature. The former are sensitive to certain model inputs, but the latter are insensitive to large variations in the same parameters. Thus, complete model validation requires temperature and composition profiles as well as effluent measurements. The insensitivity of overall model behavior to certain model parameters suggests that a “kinetics-free” model would be useful in estimating reactor performance in regions of high carbon conversion. Agreement between the kinetics-free calculation and the detailed model is very good for coals with negligible reactivity to hydrogen. © 1979, American Chemical Society. All rights reserved.
