               Description of adsorption vessel for measuring the weight loss upon reduction of metal oxide catalysts used in the Fischer-Tropsch process.  The catalyst is reduced in a vessel that is small and light enough to be weighed in an analytical balance.  It is also possible with this adsorption vessel to study the effects of treatment of the catalyst with gases other than H₂, such as synthesis gas or CO, on the surface area and pore structure, and to determine the weight loss of the adsorbent upon evacuation.
