一、前言 由于对汽油需求量的日益增加,催化叠合工艺,进入七十年代后,作为生产高辛烷值汽油组分的手段,受到了十分重视。而选择性叠合工艺是七十年代后期发展起来的新技术,目前国外仅建成二套,近年来,我国引进法国IFP专利,建成一套生产叠合油的装置,这套装置对异丁烯叠合性特别高,所生成的叠合油组分中,二异丁烯含量大于40％而碳十二烯装含量也可达30％左右,如果将这种优质叠合油作为汽油或调配油使用,最很可惜的。如何能将二异丁烯及碳十二烯烃提出来,作为十分有用的化工原料供下游产品的开发,剩下的仍作为汽油,这将获得更可贵的经济效益,是十分有意义的。
I. INTRODUCTION Due to the increasing demand for gasoline, the catalyzed lamination process has drawn great attention since the 1970s as a means of producing high-octane gasoline components. Selective stacking technology is a new technology developed in the late seventies. At present, only two sets are completed in foreign countries. In recent years, China has introduced a patent from IFP of France to build a set of devices for producing laminated oil. The sex is particularly high, the resulting composite oil component, the diisobutylene content of more than 40% and the content of carbon dodecene up to 30%, if this high quality laminated oil as gasoline or deployment of oil use, the most It is a pity How to bring out diisobutylene and carbon dodecene as the useful chemical raw materials for the development of downstream products and the remaining still as gasoline will gain more valuable economic benefits and it is very significant.
