中文摘要：
提出了一种纤维素燃料乙醇废液大规模资源化利用的新方法—将纤维素燃料乙醇废液与煤共混制备废液煤浆作燃料用。借助旋转黏度计对废液煤浆（WLCS-CEF）进行流变性测定,研究了成浆浓度、废液加入量和添加剂对煤浆流变性的影响。结果表明,废液煤浆的表观黏度随成浆浓度及废液加入量的增加而增大,添加剂的加入明显改善废液煤浆的流变特性。废液中大分子量的木质素及未水解完全的纤维素和半纤维素能起到稳定煤浆的作用,同浓度下的废液煤浆比水煤浆稳定性高,且煤浆稳定性随浓度增大而增强,合适的添加剂也能改善稳定性。当选择添加剂A,成浆浓度为62%,废液添加量为煤量的2.5%时,制得的废液煤浆比较适合气化。
英文摘要：
A new method to recycle waste liquor from cellulose ethanol fuel was suggested.It was mixed with coal to prepare slurry which could be utilized as fuel.Rotating viscometer was used to determine the rheology of waste liquor coal slurry of cellulose ethanol fuel（WLCS-CEF）.The effects of slurry concentration,dosage of waste liquor and additive on rheology of WLCS-CEF were studied.The apparent viscosity increases with the increasing of solid concentration and dosage of waste liquor.Additive could improve the rheology greatly.Constituents with large molecular weight in the waste liquor（lignin,cellulose and semi-cellulose） are not hydrolyzed completely,which is able to stabilize the WLCS-CEF.Meanwhile,the stability of WLCS-CEF is better than coal-water slurry at the same concentration.The stability of WLCS-CEF increases as slurry concentration increased,and suitable additive can also improve its stability.When additive A was used,and the concentration of WLCS-CEF is 62% with the waste liquor dosage of 2.5%.It is much more suitable for gasification.
