higher hydrocarbon meaning in English
高级烃
Examples
- In some direct reduction plants , higher hydrocarbons or even oil or coal are used instead of natural gas , but the principles are the same
一些直接还原钢铁厂采用高烃甚至油或煤代替天燃气，基本原理都是相同的。 - Therefore , cap rocks with bedding faults can seal higher hydrocarbon column height and fluid pressure , and thus facilitates the formation of larger scale hydrocarbon accumulations
如果盖层中发育顺层断层，盖层的封盖能力将被大大改善，将能够封盖更大的油气高度或者流体压力，利于形成更大规模的油气藏。 - The authors anticipate this argument and note that their primary fluid inclusions lack the higher hydrocarbons that are normally associated with the most strongly 13c - depleted thermogenic methane
作者们期盼着这一论据,同时也注意到了它们的原始流体内含物中缺少了一种通常都伴随有最为稳定的13c缺失的产热甲烷的,更为高级的碳氢化合物 - Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite , vitrinite and fusinite from jurassic coals in tarim basin at different temperatures . the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds . vitrinite is mostly composed of aromatic compounds , in addition to large amount of short aliphatic - side chain compounds . whereas fusinite are dominant by aromatic structure . the study indicates that cutinite is one of the best oil source - rocks , with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks , and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential . in addition , the components of aliphatic structures of cutinite , vitrinite and fusinite decrease , the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature , and along with the rise of temperatures , the intensity of aliphatic structure and heteroatomic compounds decrease obviously , however the aromatic structure changes a little
应用显微红外光谱技术，对塔里木盆地侏罗纪煤中有代表性的3种组分角质体镜质体丝质体在不同热模拟温度下的结构组成变化特征进行了研究，结果表明：角质体结构组成中含有较丰富的长链脂族结构，而芳香结构和含氧官能团的含量则相对较少与此相反，丝质体结构组成中芳香烃占绝对优势，而脂族结构含量则很少镜质体结构组成介于角质体和丝质体之间，含有较多的短链脂族结构和芳香结构。 - In this case study , it is considered firstly that any change in hydrocarbon - charging efficiency , which has episodic characteristics , is mainly affected by the degree of both hydrocarbon - generating and gas releasing ; secondly that hydrocarbon - charging efficiency can reflect the whole process of gas accumulation well and truly ; last but not least that holding up relatively high hydrocarbon - charging efficiency in himalayan period is one of the key factors on which gas gathered and accumulated in the late period to form carboniferous gas pool in east sichuan basin
分析认为：天然气成藏过程中充注效率的变化主要受烃源岩生烃强度和天然气逸散强度的共同影响，具有相应的阶段性；天然气的充注效率能够更加准确地反映天然气的成藏过程；在喜山期天然气仍保持较高的充注效率是川东石炭系天然气晚期成藏的关键因素之一。
