油料作物秸秆快速热解及其生物油特性的研究

以油菜秸秆、脱灰油菜秸秆、花生秸秆及芝麻秸秆等为原料，在小型流化床上进行了快速热解试验研究。从纤维素、半纤维素、木质素含量与灰分含量等原料品质方面，对热解产物分布以及生物油特性的影响进行了对比分析。结果表明，不同秸秆的纤维素、半纤维素、木质素的含量不同，其热解产物分布有所不同，纤维素与半纤维素含量高的秸秆，生物油产率较高。灰分对热解产物分布影响较大，脱除灰分有利于提高生物油的产率；脱除灰分对秸秆生物油品质有一定影响，其生物油的pH值、密度、运动粘度高于其它秸秆生物油。油菜秸秆、花生秸秆、芝麻秸秆生物油主要品质指标基本一致。

Fast pyrolysis oil crops straw and characteristics of bio-oil

Fast pyrolysis on a small fluidized bed was studied with rape straw,de-ashing rape straw,peanat straw and sesame straw as raw materials.Effects of cellulose,hemicellulose,lignin and ash content on pyrolysis and bio-oil characteristics were analyzed.The results showed minor differences in pyrolysis products of various kinds of straws due to their different cellulose,hemicellulose and lignin content.Bio-oil yield was positively correlated to the straw cellulose and hemicellulose content.Ash content had noticeable effect on pyrolysis products.De-ashing may improve bio-oil yield with increased pH value,density and kinematical viscosity.The rape straw,earth pea straw,sesame straw bio-oil all showed similar characteristics.
