In this work cubic B-spline wavelets and their operational matrices of derivative and integration are applied for numerical solution of some nonlinear boundary value problems which arise in modeling a tabular adiabatic chemical reactor. Properties of these wavelets via some projection methods leads to the nonlinear problem transforms to some algebraic system. For showing the accuracy and efficiency of the introduced methods one case study of main problem is given and findings are compared with the results of alternative methods for numerical solving of this class of equations.
