The objective of this program is to develop and demonstrate a new two-stage process which will increase distillate yields and hydrogen efficiency and reduce catalyst deactivation rates. It offers the potential for improved economics with higher distillate yields and elimination of costly and inefficient interstage deashing. This progress report describes: (1) The evaluation of Illinois No. 6 Burning Star coal to be used in the first year of the program and HRI's verification of coal preparation procedures. (2) Microautoclave scoping studies which investigated first and second-stage pressure, temperature and time relationships to guide the Bench Unit Test Program. (3) Several tests on alumina substrate first-stage catalysts. (4) A bench run investigating first-stage process variables of time and pressure with lined out periods at two space velocities and recycle modes. (5) Work initiated on an engineering analysis for the new Technology Coal Liquefaction Program to improve the quantitative understanding of this technology vis-a-vis alternative processes, to develop process flow schemes, and to evaluate process economics.
