Project A.3.2 Purification and Analysis of Hydrogen Derived from Biomass Brant Peppley CRC Fuel Cells Queen’s University
Project Overview Objective: Produce hydrogen from landfill gas and other biogas sources. Problems –Low methane content and high CO 2 content –Air and nitrogen contamination –Low level contaminants that are poisons for reforming catalysts and fuel cell catalysts (e.g., sulphur, organic acids, alkali metals, siloxanes)
Project A.3.2 Task List 1.Analytical methods 2.Contaminant removal methods and evaluation 3.Evaluate catalyst deactivation by contaminants 4.Process simulation and analysis of hydrogen production from waste-derived biogas.

Siloxane Sampling System
Results and Activities to Date Siloxane sample and analysis method tested unsuccessfully –3 hr sample time inadequate –Samples (siloxane in methanol) tend to be unstable Centrifuge purification investigated by simple modelling analysis. Removal rate shows some limited promise. Counter- current centrifuge may be practical.
