An AHP with finned adsorbent heat exchanger was constructed.

A new method of scaling up calorimetric LTJ tests on small samples to predict SCP and COP is presented.

Dynamic losses through vessel walls are important.

The predicted SCP is 1.1–2.0 time measured value versus a ratio of 2–6 elsewhere.

Air mole fractions <0.1% might account for disparities in SCP and COP between prediction and measurement.
