摘　　要：糠醛渣的特性为灰分较低、挥发分较高,同时还含有少量的N和S元素,燃烧会产生NO_(x)和SO_(2)等有害物质,若处理不当将会对环境造成严重污染。采用红外快速热解炉,以N_(2)为载气,在500℃条件下,对糠醛渣进行了快速热解实验。结果表明:红外快速热解得到的焦油中含有大量的芳香类化合物,约占40%,其中以苯酚及其衍生物为主。此外,呋喃及其衍生物和酮的含量也较高,各占20%左右,同时还含有少量的醇、吡喃和蒽油等成分。The characteristics of furfural residues are low ash content,high volatile content,and containing a small amount of N and S elements.When it burns,harmful substances such as NO_(x) and SO_(2) will be produced.If NO_(x) and SO_(2) are not treated properly,they will cause serious pollution to the environment.In this study,a fast pyrolysis experiment of furfural residues was conducted using an infrared rapid pyrolysis furnace with N_(2) as the carrier gas under 500℃conditions.The results showed that the tar obtained by infrared rapid pyrolysis contained a large amount of aromatic compounds,accounting for about 40%,mainly phenol and its derivatives.In addition,the content of furan and its derivatives and ketones was also high,each accounting for about 20%,and there were also small amounts of alcohols,pyrans,and anthracene oils.
