摘要

The overall objective of this project is to develop and test feasible reaction pathways for regenerating the spent caustic and acid streams used to remove sulfur and ash from coal in the molten caustic leaching (MCL) process being developed by TRW. As an integral part of these tasks, modern analytical method are used, or developed if needed, to acquire chemical information pertaining to the regeneration of reagents and to the chemistry and mechanisms of coal cleaning. Another specific objective of the project pursued during this reporting period was an attempt to elucidate the effects of reactor materials on the removal of sulfur from coal samples during MCL. The effects were studied using NaOH alone and NaOH-KOH mixtures as leachants. 10 refs., 3 tabs.
