This is the first quarterly report of a two year program of a study in support of the Pittsburgh Energy Research Center's SYNTHOIL process for coal liquefaction. The overall program consists of three tasks: Task 1, ''Catalyst Improvement'' in which the mechanisms of catalyst deactivation and methods of reactivation will be explored; Task 2, ''Ash Effects'' in which the effect of the mineral content of coals on liquefaction will be assessed in autoclave experimens; and Task 3, ''Kinetic Studies'' in which a bench-scale reactor will be set up to study the effects of process parameters on the kinetics of hydrodesulfurization and liquefaction. Progress in each task area is reported. Various analytical techniques were evaluated for Task 1 with respect to their ability to analyze structural and compositional aspects of catalysts in the new, used, and regenerated conditions. Surface areas, pore volumes, and pore size distributions were measured and correlated with the microstructural features revealed by electron microscopy. The design of the autoclave facility for Task 2 was completed. The system will utilize a fail-safe concept that will permit operation within a manned laboratory area. The design of the modularized reactor system for Task 3 is nearly complete. Some of the significant design features are high-pressure strain gage transducers for pressure measurements, load cell gravimetric measurements of liquid transfer rates, intermediate position product-withdrawal facilities for both preheater and reactor, and digitization of analog instrumentation outputs for a data acquisition system.
