Pyrolysis liquid obtained from local suppliers in Phatthalung Province, Thailand was separated inconventional vacuum distillation into light and heavy fractions. The physiochemical characteristics and thermalbehaviour of the fractionated pyrolysis liquid were investigated. It was found that light fraction had higherwatercontent and stronger acidity than heavy fraction and pyrolysis liquid. The heating value of light fraction waslower than those of the pyrolysis liquid and
