摘 要：Corn stalk samples from Anhui,Jiangxi and Shanghai were used as test *** physical,chemical and thermo-chemical engineering characteristics were *** similarities and differences in properties of corn stalk from the three regions were determined using SIMCA-P and SPSS software in order to obtain a proper energy utilization method of corn *** results show that the corn stalk from Shanghai has significant differences from the samples of Jiangxi and *** particular,the following properties of corn stalk from Shanghai such as the contents of cellulose,calcium(Ca),iron(Fe),crude ash,volatile matter,carbon(C),nitrogen(N),and oxygen(O)are significantly different from those of Jiangxi and Anhui samples(P0.05).While other properties such as the contents of magnesium(Mg),copper(Cu),zinc(Zn),moisture,hydrogen(H),and sulfur(S)have no significant difference among samples of three *** with the corn stalk in Anhui and Jiangxi,the Shanghai samples are more suitable for the production of ethanol because of their higher ratio of cellulose to hemi-cellulose *** of its high content of ash and low calorific value,the Shanghai corn stalk is suitable for the gasification process instead of for direct combustion or bio-oil *** research can provide a reference for raw material selection for biomass energy production and utilization.
