引言MTBE裂解与MTBE合成相配套,形成了比较先进C4分离和制备高纯度异丁烯的工艺路线。这种方法与传统的硫酸抽提法比较,不存在污染和腐蚀;就其制取的产品纯度而言,优于吸附分离法。本文主要探讨MTBE裂解制异丁烯的生产工艺。MTBE是高辛烷值汽油的掺合组分。由蒸汽裂解或催化裂化的C4馏分与甲醇醚化生产MTBE的工业正在大力发展,国内也已建成多套MTBE生产装置。由于混合Ct中异丁烯和甲醇的
Introduction MTBE pyrolysis and MTBE synthesis phase, forming a more advanced C4 separation and preparation of high-purity isobutylene process route. This method compared with the traditional sulfuric acid extraction method, there is no pollution and corrosion; in terms of the purity of its products, is superior to adsorption separation. This article mainly discusses the MTBE pyrolysis of isobutylene production process. MTBE is a blend of high-octane gasoline components. The industry for the production of MTBE from steam-cracked or cracked C4 fractions and the etherification of methanol is under development and several sets of MTBE production facilities have also been built in the country. Due to mixing Ct isobutylene and methanol
