This fourth Quarterly Technical Progress Report presents the results of work accomplished during the period June 25, 1990 through September 30, 1990. The overall objective of this program is to verify the ability of the MTCI indirectly heated fluid-bed gasifier to produce a hydrogen-rich product gas from liquefaction by-product streams and from char produced in mild gasification processes. A shakedown test for mild gasification was done during this period. During this test, Eagle Butte Coal was fed at 100 lb/hr with steam fluidization. The start-up was limestone. After about 2{1/2} hours of testing, the test was terminated to make some system modifications to the lock hopper seals and the purge line. It was also discovered that the heat exchanger tubes were partially plugged with lime from the previous shakedown tests. Finally, a char production test was run for 40 hours continuously using the Black Thunder coal at an average feed rate of about 90 lbs/hr (ranging from 60 to 120 lbs/hr). Detailed elemental analysis will be performed after liquid analyses from AMOCO and DOE are obtained. 10 figs., 7 tabs.
