摘要：
This work presents two numerical approaches for solving a nonlinear partial differential equation that is used to model an adsorption column. The approaches are compared, and the influence of the size of the time and the length intervals are analyzed, in order to verify how they affect the numerical solution and the accuracy of the results. These results are compared with respect the breakthrough time, since an incorrect evaluation of this value leads to an incorrect mass balance in the fixed bed column.
