热预处理影响褐煤热解行为研究

, 2012
采用固定床反应器研究了不同气氛热预处理对内蒙胜利褐煤结构的改变,及其对后续热解行为的影响。结果表明,与原煤相比,热预处理后煤中羟基含量和芳香氢与脂肪氢的比减少,脂肪氢的相对含量增加。与未经处理的煤热解相比,N2、N2+O2、CO2气氛下热预处理后热解水收率下降,热解气收率增加,热解气中CO2含量增高,导致高位热值下降。过热水蒸气热预处理后,焦油质量收率提高3～4个百分点。热解焦油组成的变化与预处理气氛、温度密切相关,过热水蒸气200℃下预处理使得焦油中轻质组分的含量(沸点低于360℃的馏分 ...

新型氧化—混凝剂处理染料废水研究

, 2003
根据染料废水的特点，研究了自制产品新型氧化0混凝土剂处理染料废水的情况，探讨了药剂用量、pH值等因素对COD、色度去除率的影响。试验表明，当pH大于10，“染清”氧化－混凝剂的质量分数为0.03%，絮凝时间6min，静置沉淀35min时，该药剂对染料废水具有良好的处理效果，COD和色度的去除率最高分别可达97％和86％，从而证明该方法对于染料废水的处理是可行的。该处理工艺设备简单，系统运行稳定，操作方便 ...

缺血预处理对心肌细胞超微结构及 CX43 蛋白表达的保护作用

Zhongshan Daxue xuebao. Yixue kexue ban, 2006
【目的】 观察缺血预处理对缺血/再灌注心肌细胞超微结构及细胞连接蛋白 43( Connexin43, CX43) 表达的保护作用。【方法】连续观察 54 例心瓣膜病接受瓣膜置换的病人, 随机分为缺血预处理组和对照组( 非缺血预处理) 。体外循环前后取右心耳组织标本处理, 电子显微镜下观察心肌细胞超微结构的变化, 免疫组化方法测定心肌细胞纤维 CX43 蛋白表达水平, 并作图像定量分析。对比手术前后超声心动图的心功能指标。【结果】缺血/再灌注后, 缺血预处理组心肌细胞线粒体和闰盘结构基本完整 ...
