印尼褐煤与玉米芯低温共热解焦油的特性
Study on Tar Characteristics of Co-pyrolysis of Indonesian Lignite and Corncob at Low Temperature
摘要
Abstract
Low-temperature co-pyrolysis experiment of lignite-corncob mixture at differ-ent mass fraction was carried out by using a self-designed low-temperature pyrolysis device.The results show that when the corncob mass fraction is 30%,the tar yield reaches 11.70%,which is 5 3.7 5 % higher than that of the lignite pyrolysis.The thermogravimetric analysis of lignite,corn-cob,lignite and 30% corncob mixture shows that the addition of corncob reduces the initial pyrolysis temperature of coal,and the whole TG curves shift to the low temperature region,which shows obvious promotion of pyrolysis.The results of GC-MS show that the contents of aliphatic and phenol increase by 27.79% and 193.96%,while the contents of acids and heteroatoms decrease by 26.42% and 55.19%,respectively,with the addition mass fraction of 30% corncob.Moreover, the content of light oil increases from 4.68% to 27.13%,which achieves a substantial pyrolysis of tar and high-quality tar generation.关键词
