Developmental research program for clean industrial and transportation fuels from coal. Milestone report on process variable studies, July 1978-February 1979
In this subtask covering a study of process variables, a series of eight runs were made at two levels each of temperature (820/840/sup 0/F), pressure (2100/2700 psig), and coal space rate (1.6/2.5 lbs coal/hr/lb catalyst), using a 35 weight percent coal paste feed. A ninth run on this feed was performed at a temperature of 850/sup 0/F, 2700 psig, and a coal space rate of 2.5 lbs/hr/lb catalyst. Three standard condition runs using a 30 weight percent coal feed at 830/sup 0/F, 2100 psig, and a coal space rate of 1.6 lb/lb-hr were interspersed to monitor catalyst deactivation, completing the group of twelve runs which covered the effects of the three variables indicated. Nalco Spherocat 502 8/12 mesh spherical nickel/molybdenum catalyst was used. The balance of the subtask effort pertained to establishing the effect of the high viscosity feed in the first reactor on bed expansion in terms of establishing a limiting throughput. The hydroliquefaction conditions were 830/sup 0/F and 2100 psig, with a 30 weight percent coal paste as feed. A severity factor was developed to correlate hydrogen consumption as a function of reaction pressure, temperature, and coal space rate which provides a good correlation for most of the results.
