n.石油環(huán)烷(環(huán)烷屬烴；脂環(huán)烴)

In conversion comparison method, the leak is found by looking at the naphthene conversion. 轉(zhuǎn)化率比較法是根據(jù)特定環(huán)烷烴的轉(zhuǎn)化率來(lái)判斷;

For hydrocarbons with similar relative molecular weight, the KL values of paraffin, naphthene and aromatics decrease in order. 對(duì)于相對(duì)分子質(zhì)量近似的烴，烷烴KL值>環(huán)烷烴KL值>芳烴KL值；

A new type of oil - soluble imidazole corrosion delay agent has been Synthesized from naphthene acid and organic amine . 以環(huán)烷酸、有機(jī)胺為原料合成咪唑啉油溶性緩蝕劑。

The influence of natural surfactants,such as asphaltenes,resins,solid particles and naphthene,on the stability of the water in crude oil emulsion are summarized. 綜述了原油乳狀液中天然表面活性物質(zhì),如瀝青質(zhì)、膠質(zhì)、固體顆粒物以及石蠟對(duì)原油乳狀液穩(wěn)定性的影響。

The models lumped reactants into three lumps including C6, C7 and C8+.Each carbon number lump was divided into normal-paraffin, iso-paraffin, naphthene and aromatics. 改進(jìn)后的模型將重整物料分為C6、C7和C8+，每一個(gè)碳數(shù)的化合物又劃分為正構(gòu)烷烴、異構(gòu)烷烴、環(huán)烷烴和芳烴4個(gè)集總，裂化產(chǎn)物C5-作為一個(gè)集總。
