• Gas holdup was measured for gas-liquid (hydrogen gas/decrystallized anthracene oil/creosote oil) system and gas-slurry (hydrogen gas/Taiheiyo coal particles/decrystallized anthracene oil) systems in a 0.1 ton/day continuous direct coal liquefaction reactor. The measurements were carried out at temperatures ranging from 289 K to 723 K and a pressure of 30 MPa by two methods, a differential pressure method for the gas-liquid systems and a gas-quenching method for the gas-slurry system.The gas holdups for both systems were correlated with the gas flow pattern just above the reactor entrance. Though the present gas holdup data were in reasonable agreement with those published by other investigators, a difference was found between the dependencies of gas holdup on superficial gas velocity in the preheater and in the reactor.
