This report presents the results of studies to determine the technical and economic aspects of coal agglomeration. The agglomerated coal is to be used as a feed coal to a fixed-bed type coal gasification facility. Up to eight coals are examined for agglomerating properties in three different agglomeration techniques: water briquetting in a Carver press; roll briquetting in a double roll briquetter, and pelletizing on a one meter inclined disc pelletizer. The wafer briquetting functioned as a screening examination for various coal/binder combinations to be examined in roll briquetting and pelletizing. Prepared agglomerates were examined in a series of tests to determine their ability to withstand handling and gasification. These tests included: crush strength tests of green agglomerates, hot agglomerates and cured or post (agglomeration) treated agglomerates; high temperature exposure tests; tumble tests on green, posttreated and agglomerates after high temperature exposure; Burghardt tests; small scale gasifier tests; and a high temperature degradation test. Many agglomerates failed the least severe of these tests and thus, were not subjected to the more severe tests.
