熔盐裂解液化生物质的研究
Study on Pyrolytic Liquefaction of Biomass in Molten Salt
摘要
Abstract
Pyrolysis experiments were carried out in a self-designed reactor to study the effects of the composition of molten salt,biomass materials and pyrolysis temperature on pyrolytic liquefaction of biomass.The highest yield (35 % ) of bio-oil was obtained when cellulose was liquefied in ZnCl_2,while the lowest water content (21 % ) in bio-oil was obtained when it was liquefied in 66 % KCl-CuCl( molecular fraction).Nitrate was unsuitable for biomass liquefaction.Yield of bio-oil produced from cellulose was much higher than from rice straw while water in bio-oil from cellulose was lower.It was showed that biomass containing more cellulose was more proper for pyrolytic liquefaction.Pyrolysis was greatly affected by temperature,the yield of bio-oil increased at first and then decreased with the increasing of temperature.The best pyrolysis temperatures of cellulose and rice straw were about 530 ℃ and 450 ℃ respectively.Bio-oils were analyzed by FT-IR and GC-MS.The component of bio-oil was very complex,while furan substance possessed relatively high proportionality.关键词
