    • An integrated two stage process for the production of isoolefin by the dehydration of isoalcohol and the synthesis of a corresponding ether, for example the production of methyl tertiary butyl ether by (a) feeding tertiary butyl alcohol to a first distillation column reactor into a feed zone; (b) concurrently in said first distillation column reactor (i) contacting said TBA with an acid ion exchange resin catalyst as a component of a distillation structure, at a temperature in the range of 165.degree. to 200.degree. F. to dissociate said tertiary butyl alcohol to the isobutene and water, characterized in that sufficient water is maintained in said distillation reaction zone to inhibit the reaction of the isobutene with itself to form dimers and (ii) separating isobutene and water by fractional distillation; (c) withdrawing isobutene as overheads; (d) withdrawing water and undehydrated isoalcohol as bottoms, and in the second stage feeding the recovered isobutene to a second distillation column reactor with methanol and concurrently reacting methanol and isobutene at the appropriate dilution to form a reaction mixture containing methyl tertiary butyl ether.
    • 通过脱水异构醇和合成相应的醚来生产异烯烃的综合两阶段方法,例如通过(a)将叔丁醇向第一蒸馏塔反应器中进料到进料区中来生产甲基叔丁基醚 ; (b)在所述第一蒸馏塔反应器(i)中,将所述TBA与作为蒸馏结构的组分的酸性离子交换树脂催化剂接触,在165至200°F的温度下,将所述叔丁基 醇到异丁烯和水,其特征在于在所述蒸馏反应区中保持足够的水以抑制异丁烯与其自身的反应以形成二聚体,和(ii)通过分馏分离异丁烯和水; (c)将异丁烯作为塔顶馏出物取出; (d)将水和未脱水的异构醇作为塔底馏出物,在第二阶段中,将回收的异丁烯加入到具有甲醇的第二蒸馏塔反应器中,同时使甲醇和异丁烯以适当的稀释液反应,形成含有甲基叔丁基醚的反应混合物。

    • A process for the isomerization of butenes in a mixed hydrocarbon stream containing butene-1, butene-2 and small amounts of butadiene in which the mixed hydrocarbon stream is fed to distillation column reactor containing an alumina supported palladium oxide catalyst as a distillation structure. As butene-1 is produced it is distilled off upsetting the equilibrium and allowing for a greater than equilibrium amount of butene-1 to be produced. Additionally, any butadiene in the feed is hydrogenated to butenes. The bottoms, which is rich in butene-2 may be recycled to the reactor column for more complete conversion of butene-2 to butene-1. Alternatively, a portion or essentially all of the bottoms, substantially free of butadiene, may be used for feed to an HF alkylation unit.
    • 在含有丁烯-1,丁烯-2和少量丁二烯的混合烃流中使丁烯异构化的方法,其中将混合烃流进料到含有氧化铝负载的氧化钯催化剂作为蒸馏结构的蒸馏塔反应器中。 当产生丁烯-1时,蒸馏除去平衡的平衡并允许产生大于平衡量的丁烯-1。 另外,进料中的任何丁二烯被氢化成丁烯。 富含丁烯-2的塔底物可以循环到反应器塔中,以更完全地将丁烯-2转化成丁烯-1。 或者,基本上不含丁二烯的部分或基本上全部底部物质可用于进料至HF烷基化单元。
