The online version of Fixed-Bed Reactor Design and Diagnostics by Howard F. A.1 – Interactive Driver Routine for IMSL Nonlinear Algebraic Equation Solver NEQNF. Fixed beds are used in the process industries as catalytic chemical reactors, adsorption/desorption beds, thermal regenerators, heat storage devices and pebble bed heaters. The major design parameters are the pressure drop across the fixed bed, and the heat and mass transfer coefficients between the fluid and the surface of the solid phase. Equation (2) assumes that the flow is evenly distributed along the length and that the inlet and outlet manifolds do not effect the total pressure drop of the annular system.
