Claims (9)

In the production process of the gasoline mixture, a butane-based hydrocarbon mixture containing isobutene and methanol is reacted in an amount exceeding the stoichiometric amount with respect to the amount of isobutene for the etherification reaction in the first catalytic reactor. To produce an etherification product, which is a mixture of unreacted methanol, an unreacted butane hydrocarbon mixture containing isobutene, and for the hydration reaction and etherification in the second reactor, the etherification product, water and isobutane. Reacting the added butane-based hydrocarbon mixture containing ten, the total amount of methanol to isobutene in a semistoichiometric amount to produce tertiary butyl alcohol, additional methyl tertiary butyl ether, but no methanol. Production process of gasoline mixture. The process of claim 1, wherein the first and second catalytic reactors comprise an acid ion exchange resin catalyst. The total methanol to isobutene ratio in the process of claim 1 is 0.36 to 0.99 times the stoichiometric ratio. The total methanol content for isobutene in the process of claim 3 is approximately 0.75 times the stoichiometric ratio. The process of claim 1 wherein the ratio of water to isobutene in the first reactor is 1-2.5 times the stoichiometric ratio for forming tert-butyl alcohol. In the production process of the gasoline mixture, butane-based hydrocarbon mixtures containing isobutene and methanol for the etherification reaction in a multizone catalysis reactor in which each ton consists of a packed column of an acid ion exchange resin catalyst Reacting the isobutene amount in an amount exceeding the stoichiometric amount to produce an etherification reaction product including methyl tertiary butyl ether, unreacted butane hydrocarbon mixture containing isobutene, and methanol, Water and isobutene were added for hydration and etherification in a second reaction zone (Zone), in which a portion was added as pure feed to each zone of the multi-zone catalytic reactor and a packed column consisting of an acid ion exchange resin catalyst. By reacting additional butane-based hydrocarbon mixtures, the total methanol to isobutene ratio It is the stoichiometric figures a process comprising the steps that do not produce tertiary butyl alcohol, additional methyl tertiary butyl ether, but the methanol is generated. The process of claim 6, wherein the total methanol to isobutene ratio is 0.3-0.99 times the stoichiometric ratio. The process of claim 7 wherein the total methanol amount to isobutene is about 0.75 times the stoichiometric ratio. The process of claim 8 wherein the ratio of water to isobutene in the second reactor is 1-2.5 times the stoichiometric ratio to form tertiary butyl alcohol. ※ Note: The disclosure is based on the initial application.
