为了考察熔盐组成、原料种类和裂解温度等因素对生物质裂解液化的影响,在自行设计的反应器中进行了实验研究.结果表明:纤维素在ZnCl_2中液化,生物油得率最高,为35%;在66%(物质的量分数)KCl - CuCl中液化,生物油中水分含量最低,为21%;硝酸盐不适于生物质液化反应,生物油得率为零.以纤维素为原料的生物油得率高于以水稻秸秆为原料的生物油得率,而且生物油中的水分含量较低,说明含纤维素较多的生物质原料更适于裂解液化.热裂解反应受温度影响较大,生物油得率随温度升高呈先升高后降低的趋势,存在一个较优的温度,对纤维素原料而言在530℃左右,水稻秸秆在450℃左右.采用FT - IR和GC - MS对生物油进行初步分析,生物油成分比较复杂,其中呋喃类物质占有较大比例.

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.
