摘要
A lumping procedure is proposed for continuous reaction mixtures whose components undergo nonlinear reactions. A species-type distribution function is introduced to ensure that the lumped continuous mixture is kinetically consistent with the underlying lumped discrete mixture. It is shown that, if the mixture contains some virtually unreactive species, the lump after a long time will react at a second-order rate. This is true as long as the underlying unlumped reactions are irreversible nth-order with n<2 or reversible first order. When many first-order reversible reactions are lumped together, the apparent behavior of the lump can qualitatively look like that of a reversible reaction.
