Two major activities or tasks are being performed. The first activity (Task I) is the development of a process or processes to produce agglomerates from coal fines suitable for use as a feed to fixed-bed gasifiers. Seven US coals are being investigated. The second activity (Task II) is a design and cost study to examine the effects of gasifier selection on overall plant costs for a commercial-scale coal gasification facility. Task I work during the Third Quarter involved laboratory experimentation and some limited cost studies. Twenty-four different materials and many material combinations were evaluated as potential binders for coal briquettes. Potential binder materials were initially prescreened in wafer briquette tests. Of the materials tested,approximately a dozen showed good promise as a suitable binder. The most promising candidates were then used to produce larger briquetts on a double-roll press. Binderless briquetting was also investigated. In addition, work was initiated during the period in developing suitable pelletizing processes for coal fines and a tour was made of commercial briquetting plants in Europe. The results to date indicate that there is a good probability that a suitable process that will result in agglomerates that will stand up in a fixed-bed gasifier will be techincally possible for each of the seven coals being studied. The econonics of these processes, however, are uncertain at this time and are being studied. Task II work during the Third Quarter centered on (1) completing the capital and operating cost estimates for a large coal gasification plant based on Winkler gasifiers and (2) initiating the design of a similar plant based on Molten Salt gasifiers. Capital and operating costs for the Molten Salt gasification plant and for a fixed-bed gasification plant incorporating agglomeration facilities will be developed during the next Quarter.
