Study of Depolymerization and Crosslinking Reactions in Coal Liquefaction: Final Report.

摘要

The goal of this program was to characterize the depolymerization and crosslinking reactivity of low rank coals and determine how they can be optimized in liquefaction by combining high heating rates with solvent interactions. The program had the following components: an investigation of the benefits of using solvents to stabilize depolymerization fragments formed at high heating rates. The use of coals and model polymers in a set of experiments to identify the bond breaking and crosslinking rates and mechanisms. The use of the data in an expanded Monte Carlo model of depolymerization and crosslinking reactions to simulate the results of the above tasks, resulting in a model to aid process design. The results of the program are reported. 62 refs., 60 figs., 8 tabs.
