Advanced direct liquefaction concepts for PETC generic units. Quarterly technical progress report, April 1994--June 1994

PDF Version Also Available for Download.

Description

The technical approach of the contract has been expanded to provide additional economic evaluation of related process options. Additional data will be developed in the following areas to facilitate these evaluations. The effect of several modified pretreatments on liquefaction will be investigated. These include catalytic and thermal dewaxing of distillate solvents, the effect that adding light resid to distillate solvent has on hydrotreating and dewaxing, the liquefaction behavior of dense-media separated low-rank coals, and methods of selectively removing oxygen from low-rank coals. Additional chemical, physical, and performance information on improved first-stage catalysts will be developed. Upgrading of ash concentrate to ... continued below

Additional chemical, physical, and performance information on improved first-stage catalysts will be developed. Upgrading of ash concentrate to recover catalysts and improve low-rank coals will be assessed. The conversion of residual fractions to distillate by hydropyrolysis will be evaluated. The economic impact of these processes will be determined.
