Abstract

The reactivities of five lignites were studied in the hydrogen-transfer liquefaction process undet atmospheric pressure, using a hydrogenated petroleum pitch (HA240). Although asphaltene yield from Yallourn brown coal was as high as 70%, other lignites showed inferior yields. Pretreatment in boiling 0.4N hydrochloric acid enhanced the liquefaction reactivity significantly to the extent that the asphaltene yield from Berga lignite increased to as much as 70%.
