Title: | Flash co-pyrolysis of biomass with polylactic acid. Part 1: Influence on bio-oil yield and heating value | Authors: | CORNELISSEN, Tom YPERMAN, Jan REGGERS, Guy SCHREURS, Sonja CARLEER, Robert |
Issue Date: | 2008 | Publisher: | ELSEVIER SCI LTD | Source: | FUEL, 87(7). p. 1031-1041 | Abstract: | High amounts of water present in bio-oil are one of the major drawbacks for its utilisation as a fuel. One technology that shows the potential to satisfy the demand for bio-oil with a reduced water content is the flash co-pyrolysis of biomass with polylactic acid, PLA. The influence of PLA on the pyrolysis of willow is investigated with a semi-continuous home-built pyrolysis reactor. Flash co-pyrolysis of willow/PLA blends (10: 1, 3: 1, 1:1 and 1:2) show synergetic interaction. A higher bio-oil yield and a lower water content as a function of the willow/PLA ratios are obtained. Among the tested blends, the 1:2 willow/PLA blend shows the most pronounced synergy: a reduction in the production of pyrolytic water of almost 28%, accompanied by an increase of more than 37% in the production of water-free bio-oil. Additionally, PLA shows to have a positive influence on the energetic value of the bio-oil produced and on the resulting energy recuperation. (C) 2007 Elsevier Ltd.
