The objective of this work was to compare the mechanical properties between two varieties of rice straw (Hashemi and Alikazemi). The experiments were conducted at moisture contents of 71.6 and 70.8% w...
稻秆气化焦油催化裂解脱除过程模型改进与优化（Improving and Optimizing the LS-SVM Model of the Rice Straw Gasification Tar Removal Process by Catalytic Cracking）
稻秆 气化 焦油催化裂解 模型改进 优化
2010/4/1
对所建立的稻秆气化焦油催化裂解脱除过程LS-SVM模型进行了改进，将原模型的核函数由高斯径向基RBF核函数改为线性lin核函数，并对改进以后的模型进行了验证，在此基础上对稻秆气化焦油催化裂解过程作了优化。结果表明，改进以后的模型具有更好的模拟效果和泛化能力，且当催化裂解温度为949.1356℃，气相停留时间为0.9819s时，焦油催化裂解率达到最大值98.6877%。 The LS-SVM mod...
牛粪、鸡粪和稻秆混合的沼气发酵特性与工艺优化（Fermentation and Process Optimization of Mixed Cow Dung,Chicken Manure and Rice Straw for Biogas Production）
沼气发酵 牛粪 鸡粪 稻秆 温度 配比
2010/4/1
采用可控恒温厌氧发酵装置，选用牛粪、鸡粪、稻秆3种原料，按干物质比例0∶2∶1、0.4∶1.6∶1、0.8∶1.2∶1、1.2∶0.8∶1、1.6∶0.4∶1、2∶0∶1混合，研究了各配比在15℃、20℃、25℃、30℃下的厌氧发酵情况。结果表明：随温度升高，各配比产气速率和累积产气量均增大，15℃下发酵周期最长，其他温度对发酵周期影响无显著差异；不同配比下，累积产气量均呈先增大后减小的趋势，牛粪...
