Abstract:

1. In freshly prepared endothermic mixture, the mass transfer coefficient is larger than in a mixture with previous cooling of the endogas, on account of the presence of active radicals which disintegrate upon cooling. An effect analogous to cooling is obtained when the water vapor concentration in the air is high. 2. The mass transfer coefficient in decarburization in moistened hydrogen and in carburization in products of conversion of natural gas by water vapor, and also in endothermic mixture obtained by the traditional method, has to be calculated by Eq. (5). 3. The mass transfer coefficient of products of conversion of natural gas by carbon dioxide and of freshly prepared endothermic mixture has to be calculated by Eq. (6). © 1983 Plenum Publishing Corporation.
