Abstract
Adsorption-induced deformation of microporous carbon adsorbents AUK and AR-V with different genesis was measured in conditions of methane adsorption (temperature 273, 313, 353, 393 K; pressure 0–6 MPa). Thermal deformation of carbon adsorbents AUK and AR-V was measured in the temperature range of 273–573 K. Coefficients of linear thermal expansion (CTE) of carbon adsorbents were calculated in the temperature range of 273–573 K: for AUK, aT = (3 ± 0.15)·10–6 K–1; for AR-V, T = (8.4 ± 0.6)·10–5 K–1. A comparative analysis of the CTE of adsorbents and crystal graphite was implemented.
