- After the decarboxylation process the alkane produced can be degraded or "cracked" =to lower carbon number alkane s. 脫羧基作用后,所形成的烷烴能被降解或「裂解」成低碳數烷烴。
- The effectiveness and efficiency of AEEC in decreasing surface tension was increased with the increase of carbon number. 隨著疏水基碳鏈的增加 ,AEEC的 CMC降低。 並且在所測定的溫度範圍內 ,log CMC與疏水基碳鏈長度成線性關係。
- Additionally, it can be used for determining carbon number distribution of wax, paraffin in petrochemical products, and varions hydrocarbons. 利用儀器的系統配置還可以開發出其它適用於石化領域的分析方法,提高了儀器的利用率。
- The long chain alkyl benzenes in six samples show an even carbon number predominance ranging from C16 to C20 in carbon number. 樣品中長鏈烷基苯在C16-C20?圍內具有較明顯的偶碳優勢。
- The effectiveness of pour depressing depends on the constituent of crude oil,such as wax,distribution of wax carbon number,resin and asphaltene. 原油中蠟的含量、蠟的碳數分佈以及原油中的膠質、瀝青質均會影響降凝劑的效果,此外降凝效果還取決於降凝劑的分子結構。
- The results show that most of gasoline olefins are in low carbon number and the effect of GOR-Q catalyst on decreasing gasoline olefin is obvious. 結果表明:GOR-Q催化劑具有明顯減少催化汽油烯烴(主要為小分子烯烴)含量的效果。
- The lubricity of hydrocracked diesel fuel in the presence of carboxylic acids with carbon number of 18 was investigated by using high-frequency reciprocating rig (HFRR) test. 摘要 以高頻往複試驗機(HFRR)評價柴油潤滑性能,考察了碳數為18的不同羧酸對加氫裂化柴油潤滑性的影響。
- How odd they have gone through the eccentric thing! 他們經歷了多麼離奇古怪的事!
- The carbon number range or the peak carbon number of normal alkanes in crude oils shift backuard and the light/ heavy hydrocarbons ratio show decreasing trendtion. 這些變化與原油在驅替過程中的自然色層吸附作用機理和原油中各種組分的相互作用關係有關。
