The invention discloses an adsorption-calorimetry combined device and method. The device comprises an adsorption instrument and a calorimetric tester, a test port of the adsorption instrument is sequentially connected with an adsorption combined sample tube connector and an adsorption combined sample tube through a heat preservation tube, and the adsorption combined sample tube is arranged in a calorimetric temperature control furnace, and the calorimetric temperature control furnace is connected with the calorimetric tester and is of an open structure. When the adsorption instrument is a physical adsorption instrument, a static volume method is adopted for testing, a built-in pressure sensor monitors the pressure in real time, and the adsorption quantities under different balance pressures are calculated according to the change of the pressure before and after gas feeding. When the adsorption instrument is a chemical adsorption instrument, a dynamic flow method is adopted for testing, and a built-in thermal conductivity detector monitors the gas thermal conductivity signals in real time. While the physical or chemical adsorption of the material is tested to obtain the adsorption capacity, the heat change in the adsorption process is monitored in real time by using the heat tester, and the adsorption heat of the material in a real application environment is obtained by testing.
