The overall objective of the proposed effort is to verify at the laboratory scale, the ability of the MTCI indirectly heated fluid-bed gasifier to economically produce a hydrogen-rich product gas from liquefaction by-product streams and from char produced in mild gasification processes. Specifically, the proposed effort is aimed at developing an experimental technology data base by defining the process characteristics that would be required for process integration into an overall liquefaction system. This would result in substantial decreases in the cost of hydrogen for the production of competitively priced coal-derived liquid fuels. During this quarter, shakedown tests of the reactor were completed. Subbituminous coals from Black Thunder mine and Eagle Butte mine were obtained for use in mild gasification to produce char. During the initial shakedown tests, it was determined that a new pulse combustor was needed. A pulse combustor with a large aerovalve was fabricated and tested. Three shakedown tests with limestone as the fluid-bed medium were carried out at temperature from 1450{degree}F to 1550{degree}F.
