The present work effort relates to an investigation of surfactant-assisted coal liquefaction with the objective of quantifying the enhancement in overall coal conversions and the product quality. Based on the results of a Phase 1 preliminary study on the effect of several surfactants on coal liquefaction, sodium lignosulfonate was chosen as the surfactant for a detailed parametric study to be conducted at JPL using a batch autoclave reactor. These tests primarily related to thermal liquefaction of coal. The results of JPL autoclave test runs showed an increase in overall conversions from 5 to 15% due to surfactant addition over the base case of coal alone. A continuous-flow bench scale coal liquefaction process run was conducted over a 5-day period at Hydrocarbon Research Incorporated (HRI). This test showed that the surfactant is suitable for an industrial continuous recycle process, and does not interfere with the supported catalyst. After the bench scale test, a series of autoclave runs were conducted with coprocessing the surfactant and the Ni-Mo catalyst. These experiments showed that high conversions and product quality can be maintained at milder processing conditions. Based on results of the autoclave test runs, the overall product values were obtained for two stage reactors …

A search was made for improved TE materials that could have higher efficiency than state-of-the-art SiGe alloys used in Radioisotope Thermoelectric Generators. A new family of materials having the skutterudite structure was identified (cubic space group Im3, formula (Fe, Co, Ni)As{sub 3}). Properties of n-type IrSb{sub 3}, CoSb{sub 3}, and their solid solutions were investigated. Pt, Te, Tl, and In were used as dopants. The thermal conductivity was reduced by about 70% for the solid solutions vs the binary compounds. A maximum ZT of about 0.36 was measured on Co-rich solid solutions which is 160% improved over that of the binary compounds.

A phase II study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This report covers the sixth quarter of work. The major accomplishments were (1) Completion of the distillation of the liquid product from coal liquefaction autoclave reactor runs with Illinois No. 6 coal at 400{degree}C, with and without surfactant and/or catalyst at pressures of 1700 psig, (2) Batch autoclave runs at 375 and 400{degree}C with 1 wt % lignin to Illinois No. 6 coal to further define the surfactant effect of sodium lignosulfonate, and (3) a preliminary economic evaluation of the application of the lignosulfonate surfactant in an industrial liquefaction process and a proposed conceptual plant design.
