By Monika Thol, Stefan Herrig, Roland Span, Eric Lemmon| AIChE Journal Verified 1 INTRODUCTION Knowledge of thermodynamic properties is essential for many processes in chemical and process engineering as well as academic research. For industrial use, the properties have to be as accurate as possible and, additionally, easily accessible. In order to fulfill these requirements, equations of state are used. These equations are correlated to thermodynamic properties obtained with experiments carried out in laboratories.
By Roland Span, Carsten Wedler| ACS Publications@ Detailed knowledge of the pore structure evolution of fuel chars is essential for a sound description of the conversion process. The analysis of the chars by N2 adsorption at 77.36 K according to the theory of Brunauer, Emmett, and Teller has been established as a standard in pore analysis. However, at this low temperature, the diffusion of N2 in micropores is limited, and N2 is therefore not suitable for an analysis of the microporous structure.
