Consider that a solid reactant uniformly distributed within porous particles undergoes a thermal decomposition, allowing reaction products to diffuse out of the particles and to be carried away by a flowing solvent. Models of such an extraction reaction, characteristic of certain supercritical-fluid extractions, are examined for an axially-dispersed tubular reactor packed with spherical particles. The reaction mechanisms are first-order chemical reactions in parallel or series. Limiting cases of the well-stirred and plug-flow reactor, as well as linear driving-force particle mass transfer, are presented. It is demonstrated that reaction-product concentration histories in the reactor effluent are satisfactorily represented by the first term of a Laguerre polynomial expansion expressed in terms of temporal moments. Parameters from experimental data for supercritical fluid extraction of biomass are utilized to test the mathematical models. |
