ABSTRACT:

Battelle Institute completed characterization of fifteen slurry mix tank samples and issued the final technical progress report. Cold flow measurements were initiated to study the fluid dynamics of coal char/kerosene slurries fluidizing a bed of HDS-2A catalyst. Tests were hampered by plugging of lines caused by coal fines agglomeration in several process lines. At higher gas flow rates, entrainment of gas down the recycle cup became significant. After seventeen tests were completed, the pilot plant testing was postponed in order to modify pilot plant piping. Northwestern University continued development work on optical and electrical probes and began checkout of the laser holographic apparatus.  Appendix A has been entered individually into EDB and ERA.
