A Flow-DTA adsorptive calorimetric system constructed by the combination of Differential Thermal Analysis (DTA) and Gas Chromatograph is described in this paper. Through the column thermotank designed specially the DTA cell and the Katharometer are combined. A system for the inputting of sample taking the form of a rectangular pulse is assembled. The higher sensitivity and lower noise level and synchronism of DTA and Katharometer response make it possible to determine the heat effects in various adsorption processes. The reliability of this method has been verified by the fact that the results obtained in this paper are consistent with those determined by the adsorption microcalorimeter and the fact that the experimental data of adsorption equilibrium and of calorimetric adsorption heat are in agreement with each other. The system is available to investigate the adsorption and catalysis in the conditions which are approximate to those in the industrial reactions.
