  • Content Description: A multistep direct liquefaction process specifically aimed at low-rank coals (LRCs) has been developed at the Energy & Environmental Research Center (EERC). The process consists of a preconversion treatment to prepare the coal for solubilization, solubilization of the coal in the solvent, and polishing using a phenolic solvent or solvent blend to complete solubilization of the remaining material. The product of these three steps can then be upgraded during a traditional hydrogenation step. This project will address two research questions necessary for the further development and scaleup of this process: (1) determination of the recyclability of the solvent used during solubilization and (2) determination of the minimum severity required for effective hydrotreatment of the liquid product. The project will be performed as two tasks, the first consisting of ten recycle tests and the second consisting of twelve hydrotreatment tests performed at various conditions.
