For the riser reactor, the simulation result showed that the mass fraction of olefin decreased from 35.1% to 18%, and most of the olefin was converted to isoparaffin, which was useful to maintain the gasoline octane rating.

模拟结果表明，对提升管反应器而言，汽油经过低温改质反应后，烯烃含量可以从35.1%降低到18%左右，烯烃降低幅度可达48%，汽油中烯烃主要转化为异构烷烃。

Tests of FCC naphtha upgrading were conducted under such optimum reaction conditions (with a reaction temperature of 450℃), as compared with the untreated naphtha the olefin content of the treated naphtha decreased from 40.74% to 25.80%, the contents of isoparaffin and aromatics increased significantly, the computed octane number was 5.48 unit higher, yet the naphtha yield dropped 14.25 percentage points and the LPG yield increased 13.52 percentage points.

在450℃的优化条件下，催化裂化汽油改质后，烯烃质量分数由40.74%降至25.80%，异构烷烃和芳烃含量有较大幅度的增加，计算辛烷值RON提高了5.48个单位，汽油收率降低了14.25个百分点，液化气收率提高了13.52个百分点。

The reaction time has effect on the product distribution and olefine content of gasoline.

RFG-DQ催化剂和DOCO(1)都具有显著的降低汽油烯烃含量性能，但液化气收率增加，汽油收率下降，柴油收率上升。

炼油厂的汽柴油规范将进一步强化，欧盟汽油含硫将从2000年150PPm减小到2005年50PPm、2011年10PPm，芳烃含量将从2000年42%减小到2005年35%，汽油中芳烃将寻求石油化工新用途。

Fortunately, there was an overflow clipper (a device that makes it possible not to overfill a tank).

一个汽油加油站的汽油计量表坏了，幸运的是这个油站装配了一个溢流截至阀。

In addition, DMC can be regarded as an option to meeting the oxygenate specifications on gasoline.

此外，DMC还可用作汽油添加剂来提高汽油的含氧量。

The main measures of prevention polysulfide produce and elimination its influences on gasoline copper corrosion were to increase pH value of gasoline water washing environmental, to decrease oxygenous carrying in compression unstripped gas and to carry out alkali liquor replacement.

防止多硫化物产生、消除其对汽油铜片腐蚀的影响主要措施有：提高汽油水洗环境的pH值；减少压缩富气中氧气的夹带；碱液置换。

Straight-run naphthas of Yumen, Kramayi, Central Szechuan (60-130℃), and Fushuan hydrogenated shale oil (60-120℃) were platformed separately for aromatics in an isothermal reactorcontaining 80 ml.

在80毫升催化剂容量的恒温反应装置中进行了我国四种主要原油轻馏份（玉门、克拉玛依、川中直馏汽油60—130℃馏份及抚顺页岩焦油加氢油60—120℃馏份）铂重整制取芳香烃及玉门和克拉玛依直馏汽油80—180℃馏份提高辛烷值的试验。
