摘　　要：目的:改变木糖、木糖醇行业固体残渣污染严重的现状,实现酶解玉米芯水解渣残余物的转化利用,同时降低生产成本,节能降耗,利于行业的可持续发展。方法:经反复试验,确定了由酶解玉米芯水解渣残余物制备木糖醇生产专用活性炭的最佳工艺条件为:以质量浓度为80%的H3PO4为活化剂,将残余物粉碎过80目筛,按固液体积比1:2混合搅拌30min,置于马弗炉中450℃碳化活化80min。然后用76℃的清水洗至中性,120℃烘干3h,研磨成粉。结果:将自制的活性炭用于玉米芯水解液脱色可使透光度由7%增至80%左右,与外购活性炭相比效果十分接近。结论:将酶解玉米芯残余物用来制备活性炭,实现了木糖、木糖醇行业的固体污染物的零排放,同时将生产的活性碳用于玉米芯水解液的脱色,极大的降低了生产成本,这样,环境保护和节能减排双丰收,符合科学发展的要求。Objective:The objective of this research is to reduce the pollution in the xylose and xylitol industry,and utilize the Waste of zymolytic corn cob hydrolysis residue.The method can help reducing the cost,saving the energy and better for the sustained industrial development.Methods:The best preparation conditions were:activated by H3PO4 at the concentration of 85%;the Waste of zymolytic corn cob hydrolysis residue grinded and passed through a 80 mesh sieve;then,mixed with the solid-liquid ratio(v/v)1 ∶2;stir...
