Fixed bed membrane reactor for hydrogen production from steam methane reforming: Experimental and modeling approach
This work describes the results from experimental tests on the membrane reactor in terms of hydrogen recovery factor and fuel conversion at different operating conditions. A test bench for a fixed bed membrane reactor, placed in the Laboratory of Micro-Cogeneration (LMC) of Politecnico di Milano, is designed to operate in a wide range of operating conditions: the maximum temperature and pressure are respectively 923 K and 700 kPa. An hydrogen permeability value of 5.16.10(-11) mol/(msPa(0.71)) at 723 K have been determined. The best operating conditions (873 K, 500 kPa) allow to reach a methane conversion of 47.4% and an hydrogen recovery factor of 28.1%. Results are used to validate a one-dimensional finite volume model of the overall membrane reactor, solved in Matlb (R). Copyright (c) 2014, Hydrogen Energy Publications, LLC.
