摘要

采用居里点热裂解仪-气相色谱-质谱(CP-GC-MS)联用分析技术,分别对油茶籽仁和种壳在358～590 ℃条件下进行快速裂解,并对产物组分进行了分析。结果表明,随着温度的增加,热裂解产物中的组分种类逐渐增加。籽仁热裂解产物主要为脂肪酸,此外还包括糠醛、β-香树脂醇和维生素E等附加值比较高的物质; 种壳的热裂解产物中,脂肪酸的含量占5%左右,主要的产物还包括苯酚类化合物,在产物中还检测到糠醛、香草醛和丁子香酚等附加值比较高的化合物。分析认为,油茶种壳的热裂解产物包含多种工业、医药以及食品行业所需求的原料,同时,产物中的长碳链烯烃类物质可作为生物质能源进行利用。

Abstract

The product components from rapid pyrolysis of Camellia oleifera were analyzed by GC/MS as curie-point temperatures were from 358 ℃ to 590 ℃. Results showed that composition of products tended to be more complex when increased the temperature. The dominated composition in products from rapid pyrolysis of nucleus of C. oleifera was fatty acid and some high value added species such furfural, vitamin E and beta-Amyrin were detected simultaneously. The fatty acid of about 5% from rapid pyrolysis of seed shell of C. oleifera was lower when compared with that in nucleus and the major components were also included the phenols and its derivant. In addition, high value added species such as furfural, vanillin and eugenol were detected in it. The further study indicated that rapid pyrolysis of C. oleifera could provid many raw materials for chemical industry, pharmaceuticals industry and food industry.
