Hydropyrolysis of Extracted Euphorbia rigida in a Well-Swept Fixed-Bed Tubular Reactor

Tubular reactor fixed-bed hydropyrolysis experiments have been conducted on a sample of extracted Euphorbia rigida to determine the possibility of being a potential source of renewable fuels and chemical feedstock. The effects of hydropyrolysis temperature and heating rate on the hydropyrolysis yields and chemical compositions have been investigated. The maximum bio-oil yield of 39.8 wt% was obtained in H 2 atmosphere at a hydrogen pressure of 150 bar, a hydrogen flow rate of 5 dm 3 min -1 , a hydropyrolysis temperature of 550°C, and a heating rate of 100°C min -1 . Then this bio-oil was characterized by elemental analysis and 1 H nuclear magnetic resonance (NMR) techniques.
