Objective Widespread used as gasoline oxygenate additives, methyl t-butyl ether were added to gasoline to enhance the octane number, reduce carbon monoxide in exhausts and to substitute for tetraethyl lead as an anti-knock agent.starting in the winter of 1992, MTBEup to 15wt.

研究目的甲基叔丁基醚(Methyl Tert-Butyl Ether，MTBE)是一种新型的汽油添加剂，主要用来增加汽油辛烷值，提高汽油燃烧效率，减少汽车尾气中一氧化碳等有害物质的排放，并代替四乙基铅用作汽油防爆剂。

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。

A process for preparing clean gasoline features that under existance of epoxidizing catalyst and alkoxylating catalyst, the olefine in gasoline and the oxygen and alcohol take part in epoxidizing and alkoxylating reactions to generate diolmonoether or dioldiether compounds which has higher octane number, so being excellent gasoline component.

本发明公开了一种清洁汽油的生产方法，在一个具有环氧化的催化剂以及同时具有烷氧化催化组分或者催化剂的存在下，汽油中的烯烃与氧、醇、发生环氧化、烷氧基化反应而生成二醇单醚或二醇双醚类化合物，这类化合物具有较高的辛烷值，是优良的汽油组分。

The catalyst of RFG-DQ and DOCO(1) can both reduce the olefine content of gasoline dramatically, with the yield of LPG ,diesel and coke reduced and the yield of gasoline increased, as well as octane number of gasoline reduced more greatly.The olefine content of gasoline can be effectively reduced by optimizing the operation condition, lowering the reaction temperature, increasing the catalyst-to-oil ratio and using catalyst, which can improve the gasolines quantity and upgrade the gasoline.

通过优化操作条件、降低反应温度、增大剂油比和采用有效降烯烃催化剂等措施可以有效的降低催化裂化汽油的烯烃含量，提高催化裂化汽油的产品质量，达到我厂汽油产品升级换代的目的。

The said process can regenerate catalyst continuously or intermittently to maintain the catalytic activity of the alkylating catalyst for long period and has lowest loss of produce in amount and octane number while eliminating the thiofuran sulfur impurity in material.

采用该方法可对催化剂连续或间歇再生，克服烷基化催化剂一般寿命短的缺陷，并且可以长时间维持烷基化催化剂的活性；在脱除原料中噻吩类杂质硫的同时使得产品量损失最小及产品辛烷值损失最少。
