Catalyst Accessibility in High Voltatile Bituminous Coal: Quarterly Report

摘要

As reported previously, an EPR technique has been developed in this lab to determine the pore size and number distribution in high volatile bituminous coal using nitroxide spin probes I-IX of different sizes, shapes and reactivity. This quarter, the Bruker EPR/ENDOR spectrometer (ESP 300-10/7 with an ESP 350-U ENDOR/TRIPLE accessory) was delivered and successfully installed. We are pleased that we have been successful in obtaining weak but interpretable ENDOR spectra from the EPR spin probe doped coal samples. 5 refs., 3 figs.
