A Set of Calorimetric Methods for the Study of Dispersed Systems and Reaction Heats

Applications

• Measurement of the specific heat of solid and liquid substances.
• Direct heats measurement: catalytic reactions and their stages; gas and vapour adsorption; wetting and dissolution of porous and dispersed solids; liquids mixing; combustion in oxygen of organic substances (individual compounds and their mixtures), natural and synthetic fuels and others.
• Combination of calorimeters with the vacuum units for the measurement of thermal effects at low pressures as well as flow-pulse micro catalytic units with simultaneous chromatographic analysis of reagents and catalytic reaction products.

Instrument facilities

• Calvet high temperature calorimeter (“Setaram” France): temperature range 40–500° C, in power 10–100 μW.
• Calvet calorimeter DAC-1A (Chernogolovka, Russia) and calorimeter MID-200 (“Etalon” plant, Kazakhstan): temperature range 20–200° C, in power 1–10 ?W.
• Combustion calorimeter with a bomb (“Etalon” plant, Kazakhstan).

Samples requirements

For thermal effects measurement the sample weight is to provide the total sample area not less than 5–10 m². For specific heat estimation the sample weight – not less than 100 mg.
