Abstract

Solid waste is considered as one of the key feedstocks for the chemical industry to stimulate the world’s transition toward a circular economy. Therefore, a novel production process, catalytic pressureless depolymerization (CPD), for conversion of waste to high-energy density liquid fuel has been studied. More specifically, the organic fractions recovered from demolition waste and municipal solid waste were liquefied and deoxygenated in a CPD pilot plant with 150 L h–1 (4.2 × 10–5 m3 s–1) liquid fuel capacity. The produced fuels were characterized by elemental analysis, comprehensive two-dimensional gas chromatography (GC × GC), and the ISO tests for automotive diesel established by the EN 590:2009 Standard. The studied fuels showed very low oxygen contents ( 40 wt %). The carbon range of the fuel obtained from demolition wood was wider than that of the fuel obtained from municipal solid waste (C5–C29 vs. C6–C22). The flash points (54, 46 °C), the sulfur contents ...
