Abstract

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 550degrees C, and a heating rate of 100degrees C min(-1). Then this bio-oil was characterized by elemental analysis and H-1 nuclear magnetic resonance (NMR) techniques.
