Acid strength distribution on commercial carbon blacks and chemically oxidized carbon blacks was measured by automatic titration using sodium hydroxide solutions as titrants. The titration curves show that the weaker acids with pKa between 7.0 and 11.0 occur in the amount of 0.025-0.490 m eq/g, the

Factors influencing the coke yield in the carbonization of hydrogenated pyrenes were investigated from the view of reactivities of their hydrogens. The amount of hydrogen located at 4ppm in their proton NMR spectrum was found to be intimately related to the coke yield of hydrogenated pyrenes. Oxidat
Alaskan Usibelli coal was liquefied in naphthalene or tetralin under 13.78 MPa hydrogen pressure using six commercial hydrotreating catalysts of varying physical properties: Amocat lA, HDN-30, HDN-60, Shell 317, Shell 324 and Amocat 1C. Also, stepwise thermal desorption (STD) of pyridine was carried
