During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.

一般含有0.2%~2.0%的丁二烯，其在烷基化反应中，可生成一种分子量很高的粘稠重质迭合物，使烷基化油的干点升高，辛烷值降低，并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯，同时，将部分1-丁烯异构化为2-丁烯，以提高烷基化油的辛烷值。

High octane value, can significantly increase the mixed octane value of fuel and enhance antiknock performance

辛烷值高，能显著提高燃料的混合辛烷值，增强抗爆性能

After methanol is taken out, the research octane number of C5 etherealization product is about 95. The alkene content is less than 35%, the sulfur content is less than 10μg/g and the aromatics content is less than 1%, it is a clean and high quality gasoline component with high octane number.

脱除甲醇后，裂解C5馏分选择性加氢后的醚化产物的研究法辛烷值为95左右，烯烃含量小于35%，硫含量小于10×10^(-6)，芳烃含量小于1%，是一种优质、清洁的高辛烷值汽油组分。

The results show that in the case of iso-octane direct injection at the latter stage of n-heptane high temperature heat release, the iso-octane mainly undergoes high temperature diffusive combustion with stable ignition and insensitiveness to the port injected n-heptane equivalence ratio.

当异辛烷在正庚烷低温反应之前喷入，发生预混合燃烧；当异辛烷在正庚烷HCCI燃烧负温度系数区和高温放热初期喷入，主要发生预混合燃烧；当异辛烷在正庚烷HCCI高温放热末期或结束后喷入，则主要发生扩散燃烧。

Because the octane number is volatile in the process of reconciling, the timely and accurate detection of the octane number of gasoline to produce high-quality gasoline will become more important.

在调和过程中由于其辛烷值波动较大，因此实时准确地检测汽油的辛烷值对生产高品质的汽油具有重要意义。

Recommended 91 octane or higher fuel/2 (87 octane or higher for XL 883 models).

推荐了91 八炭烷或更高的燃料/2 (87 八炭烷或高为XL 883 模型)。

The analysis of the products shows that the cracking, aromatization and isomerization reaction of hydrocarbons such as octane and benzene-n-octane over the nanoscale HZSM-5 catalyst followed the carbonium ion mechanism.

产物分析结果表明，烃类在纳米HZSM-5催化剂上的裂解、芳构化和异构化等遵循正碳离子机理。

Particularly in the production of high-octane gasoline brands, alone Change processing technology and high-octane blending more difficult are generally used by adding an appropriate amount of ANTIKNOCKS solution.

如美国、欧洲就不准在无铅汽油中使用含铁燃料添加剂。非金属抗爆剂如MTBE，尽管近年来国内普遍采用，因其不能使其充分燃烧会产生致癌物而将被限量使用。

For high octane number fuels, it was found that when an additive named as DTBP is added to RON90 and iso-octane, the HCCI operation ranges could remarkably expand to lower temperature and lower engine load.

针对高辛烷值燃料不容易压燃的缺点，本文在RON90燃料和异辛烷中加入一定比例的过氧化二叔丁基，达到了控制高辛烷值燃料着火时刻、提高燃烧效率、降低排放的目的。

Vishnu entered a dark fourth dimensional dream that did not support his field or continued life.

毗瑟挐进入了一个第四密度的黑暗梦想，那里并不支持他的能量场或继续生命。
