Advanced coal liquefaction catalyst development. Quarterly progress report No. 9, October 1-December 31, 1983
The objective of this program is to identify advanced coal liquefaction catalyst and operating conditions for use in optimized, two-stage direct coal liquefaction process applications and to experimentally test catalysts in a two-stage reaction system for supporting the improvement of this process. A development plan consisting of eight project tasks has been formulated and is summarized as follows: Task 1 - project work plan; Task 2 - literature survey; Task 3 - feed materials specification; Task 4 - continuous aging unit modification; Task 5 - thermal reaction process variable study; Task 6 - two-stage optimization; Task 7 - project coodination; and Task 8 - ebullated bed testing. This report summarizes progress in tasks 5 and 6 during the last quarter. Some of the conclusions are as follows: (1) Two-stage liquefaction of Illinois No. 6 coal with a high-severity first stage dissolver and low space velocity hydrotreater offers substantial advantages over one-stage liquefaction on Amoco's continuous coal liquefaction pilot plant. Improvements are observed for solubility conversions, resid conversion and heteroatom removal. (2) The performance of the unit in high-severity first stage configuration does not degrade over the seven day period of the experiment. This indicates that the catalyst is not deactivating over that period. (3) Operation of the dissolver at low severity produces results that are not significantly better (and in some cases, worse) than one-stage processing. (4) Preliminary data indicate that two-stage liquefaction of Wyodak coal also will be advantageous compared to one-stage processing. 2 refs., 13 figs.
