Abstract

The effective thermal conductivity (KSUPe) and wall heat transfer coefficient (HSUPw) were determined in a packed bed reactor model over a range of gas mass velocities from 0 to 15,000 kg/mSUB2hr, liquid mass velocities from 5,000 to 65,000 kg/mSUB2 hr, and pressures that simulate coal liquefaction pressures from 1,000 to 4,000 psig. A correlation for KSUPe and HSUPw was developed for the range of study. Two flow regimes seem to be limited to about ten diameters, while the entrance effects for the high liquid flow seem to extend the entire length of the column. (A)
