Study of ebullated bed fluid dynamics for H-coal. Quarterly progress report No. 1, August 22--November 30, 1977

A study has been undertaken with the objective of defining the hydrodynamic properties of gas-liquid-solid systems as related to the H-coal process. To date, pertinent literature information on such systems has been reviewed and a cold flow system is being designed. A progress report on the technical progress of the various phases of the design and construction work has been presented.
