Abstract

The adsorption of propane onto a highly active microporous carbon adsorbent FAS-097 with a micropore volume of 0.97 cm³/g was studied within a pressure range up to ~1 MPa and at temperatures of 303, 323, and 333 K. The propane uptake achieved a maximum value of ~12 mmol/g. The experimental data were used for evaluating the isosteres and differential molar heats of propane adsorption, as well as their dependences on the value of adsorption and temperature. The initial heat of propane adsorption achieved a value of ~30 kJ/mol and remained almost constant over a wide range of pore fillings up to ~5 mmol/g. At a value of propane adsorption of about 12 mmol/g, the heat of adsorption decreased to 20−22 kJ/mol.

聚合物前驱体制备的微孔活性炭对丙烷（C3H8）的吸附作用

研究了丙烷在微孔体积为 0.97 cm3/g 的高活性微孔碳吸附剂 FAS-097 上的吸附情况，其压力范围可达 ~1 MPa，温度为 303、323 和 333 K。实验数据用于评估丙烷吸附的等压和差摩尔热，以及它们与吸附值和温度的关系。丙烷的初始吸附热达到了约 30 kJ/mol，并且在高达约 5 mmol/g 的广泛孔隙填充范围内几乎保持不变。当丙烷吸附量达到约 12 mmol/g 时，吸附热降至 20-22 kJ/mol。

期刊介绍： Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
