Claims (3)

최소한 4개의 탄소원자를 갖는 선형 올레핀을, 상응하는 메틸 분지된 이소올레핀으로, 구조적으로 이성체화시키는 방법으로서, 적어도 하나의 선형 올레핀을 함유하는 탄화수소 공급액 스트림을 340℃ 내지 650℃의 온도에서 이성체화 촉매와 접촉시키는 단계를 포함하며, 이때, 상기 이성체화 촉매는 하나 또는 그 이상의 1-디메션 타공 구조를 갖는 적어도 하나의 제올라이트를 포함하는 것으로서, 상기 타공의 크기는 타공구조내에서 부산물의 이량체화 및 코크스 형성을 지연시키기에 충분할 정도로는 작으나, 선형 올레핀의 유입을 허용하고 메틸 분지된 이소올레핀을 형성 및 확산시킬 수 있을 정도로는 큰 것임을 특징으로 하는 방법.A method of structurally isomerizing a linear olefin having at least four carbon atoms to the corresponding methyl branched isoolefin, comprising: a hydrocarbon feed stream containing at least one linear olefin with an isomerization catalyst at a temperature of 340 ° C to 650 ° C. Contacting, wherein the isomerization catalyst comprises at least one zeolite having one or more 1-dimethic perforated structures, wherein the size of the perforations is dimerization and coke by-products in the perforated structure Small enough to retard formation, but large enough to permit inflow of linear olefins and to form and diffuse methyl branched isoolefins. 제1항에 있어서, 상기 제올라이트의 타공 크기는 1-디멘션내에서 0.42㎚ 내지 0.7㎚임을 특징으로 하는 방법.The method of claim 1, wherein the pore size of the zeolite is 0.42 nm to 0.7 nm in 1-dimension. 제1항에 있어서, (ⅰ)알콜 및 에테르화 촉매를 함유하는 에테르화 구역으로 이성체화 유출액을 전달하여 알킬-3차-알킬-에테르를 포함하는 반응 생성물을 형성하는 단계, 및 (ⅱ)알킬-3차-알킬-에테르 반응 생성물을 회수하는 단계를 더 포함함을 특징으로 하는 방법.The process of claim 1, wherein (i) delivering the isomerization effluent to an etherification zone containing alcohol and etherification catalyst to form a reaction product comprising alkyl tert-alkyl-ether, and (ii) alkyl Recovering the -tert-alkyl-ether reaction product. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
