    • A process for producing isobutylene and methanol comprising: a first step of subjecting methyl-tert-butyl ether to decomposition in the presence of a catalyst to obtain a reaction liquid; a second step of washing the resultant with water to separate the reaction liquid into an oil layer and an aqueous layer; a third step of subjecting the oil layer to distillation to obtain a fraction containing isobutylene and a dialkyl ether from the top of a distillation column, a fraction containing methyl-tert-butyl ether and the heavy components from the bottom of the column and a fraction containing methyl-tert-butyl ether from a side cut of the column, and recycling the side cut fraction to the first step; and a fourth step of subjecting the aqueous layer to distillation to obtain a fraction containing methanol from the top of a distillation column and a fraction containing water from the bottom of the column.
    • 一种制备异丁烯和甲醇的方法,包括:在催化剂存在下使甲基叔丁基醚分解以获得反应液体的第一步骤; 用水洗涤所得物以将反应液分离成油层和水层的第二步骤; 第三步是从蒸馏塔的顶部进行蒸馏以获得含有异丁烯和二烷基醚的馏分,含有甲基叔丁基醚的馏分和来自塔底部的重组分,以及馏分 从所述塔的侧馏分中含有甲基叔丁基醚,并将所述侧馏分再循环到所述第一步骤; 以及第四步骤,从蒸馏塔的顶部和从塔的底部含有水的馏分进行蒸馏以获得含有甲醇的馏分。

    • A process is provided for producing methyl alcohol from natural gas using chlorination technology. The process includes reacting methyl chloride, hydrogen chloride, oxygen and perchloroethylene in a catalytic reactor to give methanol product and hexachloroethane and using the C.sub.2 Cl.sub.6 to chlorinate methane of natural gas feedstock in multiple thermal chlorination reactors, each with a natural gas recycle loop. These reactors are arranged in a cross-flow reactor system whereby a gas purge from the first reactor is fed to the second, and so on if necessary until a last reactor, which is vented to the atmosphere by feeding a purge steam to the catalytic reactor.
    • 提供了一种使用氯化技术从天然气生产甲醇的方法。 该方法包括使甲基氯,氯化氢,氧和全氯乙烯在催化反应器中反应,得到甲醇产物和六氯乙烷,并使用C2Cl6在多个热氯化反应器中对天然气原料甲烷进行氯化,每个反应器具有天然气循环回路。 这些反应器设置在交叉流反应器系统中,由此将来自第一反应器的气体吹扫进料至第二反应器,并且如果需要,等等,直到最后一个反应器,其通过将净化蒸汽送入催化反应器而排放到大气中 。
