1) Ca/AC desulphurizer
Ca/AC脱硫剂
2) Fe/AC desulphurizer
Fe/AC脱硫剂
1.
Activated coke,prepared from a commerical semicoke through stream activation,was used to prepare Fe/AC desulphurizers by impregnating with Fe(NO 3) 3·9H 2O,followed by drying and calcination.
考察了Fe/AC脱硫剂的煅烧温度和载铁量对脱硫活性的影响 ,并对脱硫剂进行了X 射线衍射 (XRD)和EXAFS表征 ,结果表明 :经 2 5 0℃煅烧的Fe/AC脱硫剂具有最高的脱硫活性 ,2 0 0℃煅烧 ,前驱体未完全分解 ,高于 2 5 0℃煅烧 ,会使活性组分聚集 ,二者均导致脱硫活性降低 。
3) CuO/AC desulphurizer
CuO/AC脱硫剂
4) Cu/AC desulfurizers
Cu/AC脱硫剂
6) deoxide Si-Ca-Ba
Si-Ca-Ba脱氧剂
1.
Effects of application of compound deoxide Si-Ca-Ba and the traditional deoxide Al on J55 oil well steel are studied and compared with each other.
研究对比了Si-Ca-Ba复合脱氧剂与传统铝脱氧工艺对J55 级油井钢的应用效果, 结果表明Si-Ca-Ba脱氧剂能提高J55级油井钢的纯净度, 钢的微观组织结构及钢的实物质量得到明显改善。
