    'Residence Time' in catalytic VOC removal

    What would normally be the design 'residence time' for gas flow through Platinum coated, ceramic honeycomb, catalyzer blocks ? My understanding is in order for the catalytic reaction to take place, the off-gas must reside in the catalyst bed for a certain length of time - I have heard time...
