Example Embodiment

[0104] (Example 1)

[0105] 0.3 cc of H-β zeolite catalyst (manufactured by Tosoh Corporation, Si / Al=250 (mol / mol)) was filled in a tubular reactor (tube made of SUS). The inner diameter of the tubular reactor is 14 mm and the total length is 60 cm. Fill the upper and lower parts of the catalyst with glass beads. The average particle size of the glass beads is 1 mm. After connecting this reactor to a circulating reactor, an electric furnace was used to raise the temperature in the reactor to 350°C. The raw material (raw material gas) containing olefin, oxygen / nitrogen mixed gas (oxygen concentration 10%), and water (steam) are supplied to the reactor after the temperature rises. The olefin isomerization reaction is carried out in the above steps.

[0106] In addition, the flow rates of the raw material gas, air, and water (steam) into the reactor are as follows, respectively. In addition, the oxygen concentration in the gas supplied to the reactor was 8.5% by volume, and the w...

Abstract

A catalyst for isomerizing a first straight-chain olefin into a second straight-chain olefin that has different double bonds, the isomerization taking place in the presence of 20 ppm by volume of molecular oxygen and/or water, wherein the isomerization catalyst contains Si and Al.

Description

technical field [0001] The present invention relates to an isomerization catalyst and a method for producing linear olefins using the same. Furthermore, the present invention relates to a process for the production of compounds derived from linear olefins. Background technique [0002] A linear olefin having one double bond in the molecule is useful as a basic chemical raw material in the petrochemical industry, and its use varies depending on the position of the double bond in the molecule. An internal olefin having a double bond inside is used, for example, as a reaction raw material for hydrogenation, alkylation, or the like. On the other hand, a terminal olefin having a double bond at the terminal is used, for example, in reactions such as dehydrogenation, hydroformylation, and oligomerization. In addition, among terminal olefins, C4-C8 terminal olefins (for example, 1-butene, 1-hexene, and 1-octane) used together with ethylene in the production of linear low-density p...
