摘要：

Values of the height equivalent to a theoretical plate (HETP) were determined for the adsorption of several hydrocarbons by the petroleum pitch-based superactivated carbon AX21 over the temperature range 90-120°C. It was found that the HETP values were independent of both the adsorptive and the temperature of measurement. This surprising result is interpreted in terms of a very high degree of interconnectivity of the micropore structure of AX21. It is also concluded that considerable caution is required in interpreting micropore diffusivities determined from gas chromatographic measurements. © 1990.
