Macroalage are considered to be a potential feedstock for alternative fuel. As we all known, because the high content of minerals in macroalge, they can cause the problems of corrosion and slagging. A pretreatment process of S. japonica has been required for demineralization and dewatering. In this study, we investigated the yield of products and the characters of bio-oil fractions obtained by solvent extraction. A pyrolysis on two pretreatments of S. japonica were carried out in a fixed bed reactor under different temperatures. The yield of bio-char produced by untreated S.japonica was higher than that of water pretrated S.japonica. Conversely, the yield of bio-oil and gas obtained from water pretreated S.japonica were higher than those of untreated S.japonica. Solvent extraction was proceeded with distilled bio-oil. Compared with the untreated and water pretreated S.japonica, the yield of extracted oil (16.6%) from the former was two times higher than that(7.7%) from the latter. |
