The characteristics of process streams from co-liquefaction of coal with plastics are investigated. Several components of waste polymers can be identified and sometimes quantified in co-liquefaction process stream samples. Different characterization strategies are needed to accommodate different polymers. Polystyrene (PS) and polypropylene appear to be reactive, and there is no indication that the automobile shredded residue contains an unreactive PS component. High-density polyethylene is less reactive and requires a substantial recycle rate to convert it completely. Marker compounds that appear to be primary PS products were observed in the light product range. The distribution of these light PS products suggests that little gas production is associated with PS liquefaction.
