查询词典 active carbon

Results showed that:there were significant differences in the carbon to oxygen ratioamong various positions and processingconditions;lignin and abstracts mainly made up the surface of bamboo;high temperature drying resulted in the decomposition of volatile abstracts in the surface,whichindicated some structure of cellulose and hemicellulose,while the effects of processing with boracic acid were not apparent;the bamboo processed in hightemperature and with boracic acid showed decreasedfree hydroxide and activity at the same time;the amount of active free hydroxide of inner layer was higher thanthat of the outer.

结果表明：不同部位和不同处理条件下竹材表面的碳氧比有很大差异；竹材表面主要以木素和各种抽提物为主；高温干燥导致竹材表面易挥发的抽提物分解，使部分纤维素和半纤维素的结构特征得以显露，而硼酸处理效果不明显；高温处理和硼酸处理后竹材表面的自由羟基减少，活性降低；竹黄表面的活性自由羟基的数量高于竹青表面。

The results show that the perfect strength can be obtained under oxygen partial pressure about 20% O2, overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction firstly when carbon-burdened hematite pellet is roasted in oxidizing atmosphere, and then the magnetite will be oxidized to secondary hematite, which is more active than original hematite, therefore, the induration strength of pellet is able to be enhanced.

研究结果表明：内配碳赤铁矿氧化球团在接近空气配比(氧含量约20%，体积分数)的氧化性气氛中焙烧强度最大，氧含量过高或过低都会影响Fe2O3的再结晶，使球团强度降低；在氧化性气氛中焙烧含碳赤铁矿球团时，原生赤铁矿先还原为磁铁矿，磁铁矿再氧化成活性较高的次生赤铁矿，提高了赤铁矿焙烧固结性能和球团强度。
