Microautoclave Reactor System Study of SCT Coal Dissolution Parameters. Final Technical Report. Volume 3

摘要

The Integrated Two-Stage Liquefaction (ITSL) pilot plant first stage simulated in this study is essentially a coiled reactor into which coal, process solvent and hydrogen gas are fed. The nominal reactor conditions were: inlet and outlet temperatures of 610 exp 0 F and 830-865 exp 0 F, respectively; 2000-2500 psig pressure at temperature; and a residence time of less than 10 minutes. The purpose of this investigation was to provide data to aid in the optimization of the first stage of the ITSL process with a minimum expenditure of time, manpower and funds. The experiments were conducted in a micro-autoclave reactor system which allows for very rapid changes in the reaction parameters (ten to fifteen per week). These experiments were designed to investigate the Short Contact Time (SCT) reaction parameters of temperature, pressure and residence time using different combiations of coal and process solvent. 34 figs., 36 tabs.
